H. Watanabe, ... J. Tournebize, in Pesticide Risk Assessment in Rice Paddies, 2008. Armando Gómez-Guerrero, Timothy Doane, in Developments in Soil Science, 2018. 3d. In addition to the overall capacity to store water, soil texture also influences NPP through its control of water availability, according to precipitation and the final balance of air and water in soil (Gomez et al., 2002: Delgado-Caballero et al., 2009). For fine-textured soils, AW increased by 19% in the field and lab studies, and 13% in the GH & pot studies (Fig. A summary of the feedstocks and the pyrolysis conditions used to produce the biochars for the various studies considered is provided in Table 1 and Fig. Results reported here are NH4+ and NO3− production during a 10-day incubation (25°C, 25% moisture content) of Ap horizons. The feedstocks were mainly from wood and straw. Determining the ultimate use of trees is a vitally important step in species selection. The net effect of such events is usually much greater than either event alone (David Tongway, pers. Only the results from the chambered measurements will be reported here. Microbial activity in soil, which is also related to carbon stabilization and storage, is influenced by the effect of texture on water holding capacity and aeration. (2019); Jin et al. Pates Creek exhibits similar water quality changes that have occurred in the groundwater. For full details on this trial and leaf beetle assessments, refer to Rapley et al. Soil texture includes light (sands and sandy loams), medium (loams and sandy clay loams), and heavy (clays, clay loams, and sandy clays) options. There are two subregions, that is, Deltaic Alluvium subregion which comprises three blocks Balianta, Balipatna, Chilika, and Lateritic subregion covering Banpur, Begunia. A transitional AB horizon with a loamy sand texture and few vine roots was positioned on two Bw horizons and a BC horizon. The drainage of loam soil is usually affected by its composition. In general, average BD for the soil textural groups decreased after amendment. The open-top chamber site was located at the Institute of Forest Genetics in Placerville, CA. Table 2. However, in case of a balanced mix, it oscillates from 4 to 6. Altitude, rainfall, temperature, and soil properties are the main environmental categories used in the Tree Species Selection Module to determine which species can grow on particular sites. Exclamation marks in the first column indicate potential problems, such as possible risk as weed species. CLIFFORD N. DAHM, ... FRANCES P. GELWICK, in Rivers of North America, 2005. For the fine-textured soil group, WP marginally decreased regardless of the experimental type. After 102 days of incubation, variation in carbon mineralization for all soils ranged from 0.5 to 1.9 mg CO2-C g−1 for the top soil and from 0.4 to 1.0 for the second depth. The total population of the district is 1,877,396 comprising 986,886 males and 890,509 females. Due to the low clay and organic matter content these soils have low aggregate stability. (2013); Sun et al. Soil Profile – Soil Horizon: O horizon, A Horizon, E horizon, B Horizon, C Horizon or Parent rock, R Horizon or Bedrock. Clayton County is located in the metropolitan Atlanta, Georgia area and has few heavy industry waste dischargers. These soils are fertile, simple to work with and provide good drainage. (2012); Novak et al. Loam. In addition to plant-mediated changes in soil structure, temperatures changes that lead to waterlogging (due to a reduction in snow cover and/or thaw) and salinity/alkalinity are also expected to detrimentally affect soil biota and soil structure under warmer conditions (Karmakar et al., 2016; Scharpenseel et al., 1990). Solanum nigrum cultivated on different soil texture types, sandy clay loam, silty clay loam, clay loam, loam, and control soils, were evaluated for proximate compositions, antinutrients, vitamins, and mineral composition with plant age using standard analytical methods. Later, analysis of metal and coliforms was discontinued except for a few interior and down gradient wells on an annual basis. A—0 to 10 inches; silt loam Bt—10 to 42 inches; silty clay C—42 to 60 inches; silty clay loam Minor Components Wabash Composition: About 10 percent Slope: 0 to 1 percent Drainage class: Poorly drained Flooding hazard: Depth to seasonal water saturation: feet 4752—Sogn-Vinland Complex, 3 to 25 percent slopes Map Unit Composition The irrigation system is solid-set buried PVC and ductile iron with galvanized steel risers and brass and plastic sprinklers. (2002); Powers et al. In addition to the physical effects of temperature on moisture retention, there can be significant effects on saturated hydraulic conductivity. Annual denitrification in wastewater irrigated forests and adjacent nonirrigated forests in the Piedmont of the southeastern USA. com.). When the dataset was disaggregated into textural groups, for the coarse-textured soils, WP increased in the GH & pot and field studies by 85% and 16%, respectively, but slightly decreased in the lab-based studies (by ~2%) (Fig. The water soil potential can also be important in this relationship with more negative potentials in clay soils due to the matrix potential effect. Overview of the lysimeter facility at NIAES. The percentage increase was significant only for the former textural group. Sand. Clay 50% / Silt 40% / Sand 10%. From Middle English lome, lame, lam, from Old English lām (“clay, mud, mire, earth”), from Proto-Germanic *laimaz, *laimô (“clay”), from Proto-Indo-European *ley- (“mud, slime; to slip, slide”). Each of the chambered treatments was replicated three times, and each of the unchambered treatments was replicated twice. Particle size of the biochars ranged from 0.03 and 8.0 mm with a median of 2.0 mm (Fig. The soil is Aiken clay loam, a xeric haplohumult derived from andesite. An example of the role of soil texture in modulating the effects of climate change has been observed among Quercus suber forests in southern Spain (Ibanez et al., 2014), the survival of which is related to soil moisture, itself controlled by texture. In this horizon, peds were covered by clay cutans, indicating that a translocation of colloids from the upper horizons had occurred. Figure 2 shows the results of a simple search carried out using the Forestry Compendium. (2016); Gamage et al. The four lines for each soil texture represent soils with different organic carbon content. The columns following the species name indicate whether it has fully satisfied (+), partially satisfied (+/−), or failed to satisfy (−) the particular criterion. The changes in FC with biochar application for the soil textural groups are shown in Fig. Nitrate-nitrogen concentrations, on the other hand, in the down gradient well have increased to an average of 0.5 mg l−1. Fig. 4. Highlighting the name of the disease and selecting a ‘soft link’ button brings information about the disease onto the screen. These transport sedimentary material mainly toward the sea and reduce the accretion rate of tidal flats (Gao, 2009). Wear of rotary plows operating in a tropical clay loam soil Eng. Interaction between ingressing marine saline water and land-derived fresh waters differ between estuaries and river systems, and accounts for many local ecological variations in the expanse of mangrove of the delta. (2014); Peake et al. This did not happen every winter, however. The conifers were dominated by Pinus ex gr. Common upland vegetation types from the Edwards Plateau to the coast are juniper–oak–mesquite savannah, blackland prairie grasses, oak hickory forest, oak savannah, and coastal prairie grasses. We use cookies to help provide and enhance our service and tailor content and ads. Soil texture is therefore a useful parameter to consider when predicting the effects of climate change on forest ecosystems, not only because of its influence on important variables such as water content but also because of the correlations between texture and soil carbon dynamics and vegetation distribution (Haxeltine et al., 1996; Schimel et al., 1994), Walter G. Whitford, ... Benjamin D. Duval, in Ecology of Desert Systems (Second Edition), 2020. Water viscosity is dependent on temperature. Overall, the transitional areas that change in vegetation are likely to experience this change in structure. 14–42 in: Brown to yellowish brown, clay, well aggregated, angular blocky 1½ to 1/2 in slight degree of sub-plasticity, with light to moderate amounts of soft and concretionary lime and usually the fine earth effervescences to dilute acid. Reeves Creek and Rum Creek, the two nonirrigated background monitored streams, have similar specific conductivity and nitrate-nitrogen concentrations as Pates Creek and chloride concentrations are similar to and unchanged from the initial preirrigation concentrations in Pates Creek. To build loam soils these elements are mixed with organic matter, water, and air. The user can select a wide variety of options within the four main headings of uses, distribution, environment, and silviculture. For example, Lophodermium pinastri causes needle cast problems for Pinus sylvestris (Scots pine) in nurseries and in young (2–5-year-old) high-density plantations. 1, 4, 8, 9, 10; hourly data recorded for No. Percolation from the lysimeters with shallow-rooted grass was appreciably larger than from those in which pine and chaparral ecosystems occupy a deep soil volume. The Krasikovo Interglacial has been recognised on the basis of palynological studies of the section near the Krasikovo Village, Konakhovo district in the Tver’ region. The effects of climate change in arid environments, therefore, will not only depend on the effect of soil texture but also on the temporal distribution of precipitation. Other feedstocks such as manure residues, various sludges, insects, and shells constituted only a small proportion of the dataset (Table 1). The composition maps show this part of Nebraska to have a high percentage of sand (dark brown), little silt (light pink), and little clay (light teal). It was installed in the agricultural year 1997/1998 in Jaboticabal-SP, Brazil (21°13ʹ57.96ʺ S and 48°17ʹ6.18ʺ W). (2017); Kameyama et al. Soils were sampled intensively prior to chamber establishment and found to be very uniform. The biochars were largely obtained by slow pyrolysis (constituting about 79% of the dataset). Water quality monitoring has been conducted at the head of the reservoir and at two tributary streams that do not receive wastewater irrigation but are experiencing expanding urbanization. Spring wheat, pea, a vetch-oats mixture, spring barley, sweetclover, and trefoil were used for recultivation in unfertilised and NPK-fertilised plots. 2). In the recultivated plots, the activity was measurable in samples collected in summer. Tidal creeks are also a feature of adjoining unvegetated mudflat or sand flat. Tags: Question 10 . Large logistic costs associated with the transportation of raw materials commonly result in the dragging of local streams in order to obtain the necessary sand and gravel. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. loam or clay to refer to a range of particle sizes in a soil. Fine particles have higher specific surface area and are more reactive than coarse particles, therefore clay-textured soils generally store higher amounts of carbon than sandy soils (Sulman et al., 2014). (2019); Alkhasha et al. Pearson correlation coefficients between BCad vs. percentage change (% Δ) in bulk density (BD), soil water content retained at field capacity (FC), wilting point (WP) and plant available water content (AW) for coarse-, medium- and fine-textured soils. The first CD-ROM version of the global module was released in 2000 and a revised version was issued in 2003. Loam is soil composed mostly of sand, silt, and a smaller amount of clay. Mangrove swamps with adjoining unvegetated mudflat, sand flat, or mixed sand flat dominate the intertidal areas of the Niger Delta estuaries. 2), and the test plants have been maize (Zea mays L.), sunflower (Helianthus annuus L.), and crotalaria (Crotalaria juncea L.), as shown in Table 1. SURVEY . To understand these effects, it is important to consider the three main properties of water affecting how it behaves in soil: viscosity, surface tension, and contact angle. A step by step guide to crops suitable for Loam soil (2018); Lima et al. (1976, 1979) determined the actual dehydrogenase and catalase activities, numbers of microorganisms, and respiration (CO2 evolution) in sulphur strip mine spoils (the Podorozhnen mine, Rozdol), submitted to agricultural recultivation. It is silty clay loam or silt loam. Landscape function analysis focuses on the central role of soil in arid and semiarid ecosystems (see Chapter 1) and how wind and water redistribution patterns affect ecosystem function. (2019); Baiamonte et al. (2014); Rogovska et al. Percolation of Water from Lysimeters at Coshocton, Ohio, Mean 1947–1955a. Another indirect effect of texture is its influence on the amount of solar energy retained by the surface soil. Loam soil is a mixture of sand, silt and clay that are combined to avoid the negative effects of each type. Sandy clay and silty clay were the least studied soil types with only one experiment each. Soil texture categories include silty clay to heavy clay, sandy clay loam to sandy clay, sandy loam to silt-loam, sandy soil to clayey sand. 3b. The complex phytocoenoses included Pterocarya, Juglans and Ilex, and the undergrowth contained diverse bushes. Gray lowland soil was sampled from the upper and lower layer of a paddy field in Mizukaido and filled for each layer (0–60 cm and 60–200 cm) of the lysimeter. 5.13). Fig. Altitude, rainfall, and temperature data can be entered as single numbers or ranges. (2018); Gunal et al. The soil has a sandy clay-loam texture (67% sand, 6.5% silt, and 26.1% clay); it is classified as Ferralsol ( WRB, 2014 ), and the climate is typically tropical, rainy and hot in the summer months, dry and cold in the winter months, classified as Aw according to Köppen's classification ( Peel et al., 2007 ). Artificial pads commonly have soil characteristics that are different from natural landscape settings. Pavanasam Natarajan Ananth, ... Jitendra Kumar Sundaray, in Agricultural Extension Reforms in South Asia, 2019. (2018); Glab et al. Nenibarini Zabbey, ... Bolaji Benard Babatunde, in World Seas: an Environmental Evaluation (Second Edition), 2019. This is a common feature of the extensive Nigeria coastline fringing the Atlantic Ocean and the numerous estuaries that connect the ocean. Wastewater irrigation is limited to 6.3 cm water week−1 which has resulted in maximum N applications of about 395 kg ha−1 year−1. The correlation between percentage change in AW and BCad was moderately strong for the fine-textured soil (r = 0.52), followed by the medium-textured soils (r = 0.21) and weak for the coarse-textured soils (r = 0.18). Full data sheets include sections on name, importance, botanical features, geographic distribution, environmental amplitude, silviculture and management, protection, variation and breeding, uses, disadvantages, and references. 3 are mean values for the soil textural group categorization adjusted for the covariate (BCad) at a mean value of 1.68% for the whole dataset. The pH values ranged from 7.4 to 9.02 with an average of 8.34. (2018); Obia et al. (2014); Sun and Lu (2014); Tammeorg et al. 4% carbonates. Percentage change in soil bulk density (BD), soil water content at field capacity (FC), wilting point (WP), and plant available water content (AW) for (a) coarse-textured, (b) medium-textured, and (c) fine textured soils grouped according to experiment type (GH & pot indicate studies conducted in the greenhouse and pot experiments) and adjusted for the added biochar carbon. For example, people are rapidly buying up Hill Country (the commonly used name for the Edwards Plateau) property as tourism has begun to edge out agriculture as an economic base in the region. Depending on their predominant composition they can be either sandy or clay loam soil. In general, trees irrigated with wastewater have higher foliage nutrient concentrations and exhibit more rapid growth than trees grown on adjacent sites without irrigation. Thus if increased temperature causes reduced capillary pressure for a capillary of a given size, it will drain sooner under warmer conditions leading to a lower volumetric water content at that suction. Sandy soils are often very acidic. The mean rate of percolation was greatest–approaching 1.5 mm day−1–in late winter, declining thereafter except in years of heavy spring and summer rains. Silty Clay: Silt has larger particles than clay and is mainly inorganic in nature.A silty clay soil has a higher percentage of clay than silt. In the first year, dehydrogenase activity was lacking in the control heaps. The amount of total organic carbon in these soils follows the order loam > clay > sandy loam, which can be explained in part by parent materials, respectively, of andesite, basalt, and granite (Powers et al., 2005; Rasmussen et al., 2006). Greater percolation from shallow-rooted than deep-rooted grass occurred in a long series of measurements in lysimeters containing undisturbed silt loam at Coshocton, Ohio (Table IV). During the pre-plantation period, 3 Mg ha−1 per year of limestone was distributed to increase soil pH. The most frequent monitoring is conducted at wells located down gradient from the irrigation site. Considering the most mobile constituents monitored (chloride and nitrate-nitrogen) and specific conductivity, there have been increasing trends to what appears to be a plateau concentration for chloride and specific conductivity and an initial slight increase in nitrate-nitrogen with no long-term increasing trend since irrigation began in 1983. In contrast, chloride concentrations and specific conductivity in the down gradient wells (immediately outside the irrigation area) have steadily increased from 10 to 20 mg l−1 and from 80 to 150 uSc m−1, respectively. Loams are comprised of a mixture of clay, sand and silt that avoid the extremes of clay or sandy soils and are fertile, well-drained and easily worked. It is silty clay loam or silt loam. There is a general increase in the predominance of clay minerals in sedimentary rocks with decreasing grain size (Fig. However, because of the clay particles in the soil, loam tends to hold water relatively well. loamy; Translations During February–April 1991, 24 hexagonal open-top chambers (3.6 m in diameter) were established on the site. The FC for the medium-textured soils marginally increased by 13% compared to the fine-textured soils in which FC remained unchanged (<1%) after biochar application. Table 2. Do agents of disturbance and stress recur frequently (e.g., defoliation of grasses by herbivores), less frequently such as storms and fires, and how predictable are these stresses? Table 1. Pollen diagram of the deposits nearby Krasikovo Village (Shick et al., 2006). The soils of this area have very deep to shallow deep effective soil depth and ranged from 45 cm to 150 cm with an average of 120.6 cm. (2012); Kameyama et al. Aeration: The varied particle sizes in loam create a loosely-packed soil that allows oxygen to flow freely to plant roots. In general, the fertilisers applied in spring caused a decrease of activity in spring and an increase in summer and autumn. (2012); Revell et al. A loam is a soil mixtures that is named for the type of soil that is present in the greatest amount. Table 3. Loam is a mixture of clay, sand and silt and benefits from the qualities of these 3 different textures, favouring water retention, air circulation, drainage and fertility. Soil aggregates may cause different biogeochemical responses to soil warming by affecting the spatial distribution of soil microorganisms, C and nutrient (N and P) cycling, as well as water and oxygen fluxes by restricting their movements or interactions in soil (Fang et al., 2016; Puissant et al., 2017; Zhang et al., 2013). For example, changes from tundra to forest and from forest to grassland are likely to have a favorable effect (increase aggregation) on soil structure, even on annual or subdecadal timescales, while temperature changes leading to desertification would have unfavorable implications for soil structure at decadal or shorter timescales. The Forestry Compendium's Tree Species Selection Module provides the option to select a species on the basis of its country or region, or on latitudinal limits. (2017); Aller et al. By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. Well I mixed the clay subsoil with the sandy topsoil and I added compost, the universal soil improver and the result is a loam. The sizes of the flats range from 1.5 km in length to 12 km (Ibe, 1988). Clay minerals are oxides of aluminum and silicon, which are called aluminosilicates. The rate 5.0 Mg ha− 1 was chosen for supplying the N required by maize (one-third of the SS N is available for maize). 7.3 presents data for CO2 evolution measured in three soils representative of Northern California forests at a constant temperature (22°C) and relative water content (50% of water holding capacity). (2017); Madari et al. The experimental plots are 60 m2 (6 × 10 m) (Fig. The implications of the influences of structural change on biogeochemical cycling are discussed in depth in “Factors and feedbacks that indirectly affect the physical properties of soil” and “Implications of atmospheric warming for the biogeochemical cycling of carbon, nitrogen, and phosphorus” sections. Various silvicultural characteristics can be selected within the Tree Species Selection Module. Figure 3. For starters, it can retain moisture and nutrients; therefore it is better suited for farming. The families in the trial were derived from open-pollinated seed collected from trees in native stands representing nine of the populations from throughout the range of E. globulus. The infiltration through the soil matrix is collected in a bottom pan (1.90 m × 1.90 m) and the edge flow along the concrete surfaces is collected outside of the bottom pan; then these outflows are drained through separate pipes equipped with tipping-bucket flow meters (Takagi et al., 2001). In geology, the soil textural triangle determines the proportions of clay, silt, and sand in soils. (2016); Kameyama et al. For example, light soil refers to a soil high in sand relative to clay, while heavy soils are made up largely of clay. Seedlings were dried, weighed by major component (foliage, branch, stem, roots), and analyzed for N on a Perkin-Elmer 2400 CHN analyzer. Depending on their predominant composition they can be either sandy or clay loam. The means were adjusted for the covariate, the added biochar carbon. D. Loam Soil. Twenty-two groundwater wells as well as several private water supply wells in and around the site have been monitored. The general pattern of the tidal flats observed from the supratidal zone to the subtidal zone is the mangrove swamp, unvegetated mudflats, mixed sand flats, and sand flats. Peterson et al. Such loamy soil is referred to as agricultural soil because it contains a mixture of all three types of soil materials being sandy, clay, and silt, and hummus is also contained. Derived terms . 4a–c). Particle size distribution of soils used to investigate biochar effect on soil water retention. The dry-well type lysimeters consist of a model paddy field and an upland field (Figure 5). Now, the soil comprises two Ap horizons, about 25 cm thick, produced by the annual mechanical working of the soil. (2014); Abel et al. Several tidal creeks of variable length and width radiating from the main feeding channel cut through or end blindly in the mangrove swamps (Onwugbuta-Enyi, Zabbey, & Erondu, 2008). The importance of soil texture on forest productivity and carbon and nitrogen cycling is evident in moist tropical and arid environments as well. The site is entirely forested and about 50 ha are harvested annually. Unfertilised spoil heaps (clays and sandy loams; pH in KCl solution was 4.6-5.6) under ruderal vegetation served as controls. The deeper BC horizon had a texture and structure similar to those of the Bh; the tendency of the blocks to break into crumbs was here attributed to the abundance of vine roots. Int. Warming-induced changes to the physical behavior of water will influence the relationship between soil water content and soil water potential, commonly referred to as the “water retention curve.” For most soils, the reduction in water content with increasing temperature at a fixed matric potential is less than 0.001 m3/m3 for an increase of 1°C (Bachmann et al., 2002; Schneider and Goss, 2011). In October 1991, three trees from each chamber were harvested, including complete root systems. In evaluating landscape function, soil surface assessment is combined with grass cover, tree and shrub cover, litter cover, cryptogam cover, degree of crust brokenness, erosion type (wind or water), rills and gullies, deflation (dunes), deposited materials, surface roughness, soil aggregate stability, and soil texture. Treatments were begun in May 1991. 2. The existing plantations or forests supplying a particular facility may already indicate the only acceptable species. (2015); Mollinedo et al. Silt soil will feel soft and can be formed into a loose ball when wet. For example, annual average temperature at Cuero, Texas, is 21.0°C, with minimum average monthly temperature of 11.0°C in January and maximum average monthly temperature of 29.0°C in July and August (Fig. G. Corti, ... S. Cocco, in Biogeochemistry of Trace Elements in the Rhizosphere, 2005. An experimental facility for studying the fate and transport of agrochemicals was established at NIAES in 2000. Urbanization with increased emphasis on recreation and tourism is expanding substantially in the San Antonio/Guadalupe drainage basin. The Forestry Compendium provides information on insect pests, diseases, and parasitic plants which may cause problems for particular trees within each species description. The bare-soil lysimeter took in little water through the soil surface, so there was little to be divided at the subsequent branching between soil-moisture take-up and percolation; percolation got none. B horizon hydraulic conductivities average 9×10−4 cm s−1. The interpretation drawn from the steadily increasing chloride and specific conductivity and no increasing trend in nitrate-nitrogen is that plant uptake and denitrification, which occurs at higher rates in irrigated areas than in nonirrigated forests (Figure 2), are occurring to the extent that little nitrate is reaching the groundwater. Soils on a Warmer Earth: Effects of Expected Climate Change on Soil Processes, With Emphasis on the Tropics and Sub-tropics: Proceedings of an International Workshop on Effects of Expected Climate Change on Soil Processes in the Tropics and Sub-tropics, 12–14 February 1990. The particles of clay are very small, which is one of its most important characteristics. 3). The experiment has been carried out for 18 consecutive years with annual applications of SS. Surface tension reduces linearly with increasing temperature, and contact angle decreases with increasing temperature for most soils, though not all (Bachmann et al., 2002). Changes in BD with biochar amendment for the soil textural groups are shown in Fig. Copyright © 2020 Elsevier B.V. or its licensors or contributors. 30% quartz and chert. (2013); Ibrahim et al. A systematic review and meta-analysis, Fatemeh Razzaghi, ... Emmanuel Arthur, in. Infestation level of each tree was determined by summing the number of egg batches and larval clutches. Loam soil facilitates plant growth in three key ways. For the model-upland field, a dry well with 1.5 m diameter and 5.5 m depth was prepared in the same way as in the model paddy field but with the soil type of Andisols-loam and loam. The results show the dominant texture of sand clay loam, sandy loam, loam and, Does biochar improve soil water retention? The clay content ranges from 25 to 35 percent. All the monitored data are stored through the online monitoring and data acquisition system as indicated in Table 8. Silicate minerals make up about 90% of the rock-forming minerals of the earth’s […] The soil has a sandy clay-loam texture (67% sand, 6.5% silt, and 26.1% clay); it is classified as Ferralsol (WRB, 2014), and the climate is typically tropical, rainy and hot in the summer months, dry and cold in the winter months, classified as Aw according to Köppen's classification (Peel et al., 2007). Increased infiltrating water temperatures will likely lead to an overall increase in the drainage of soil water under warmer conditions. These soils are strongly to extremely calcareous soils. Mean percentage change in (a) bulk density, (b) soil water content at field capacity (FC), wilting point (WP), and plant available water content (AW) for coarse-textured, medium-textured, and fine textured soils. Where these soils are freely draining, and well structured, they have low risk of runoff.
