Long‐Term Fertilization Influences on Clay Mineral Composition and Ammonium Adsorption in a Rice Paddy Soil
Soil Science Society of America Journal - Tập 72 Số 6 - Trang 1580-1590 - 2008
Yanli Liu, Bin Zhang, Chengliang Li, Feng Hu, B. Velde
Increasing NH4+ adsorption can be an effective alternative in building an available N pool in soils to optimize crop recovery and minimize losses into the environment. We hypothesized that long‐term fertilization may change NH4+ adsorption due to changes in the chemical and mineralogical properties of a ric...... hiện toàn bộ
Effect of Environmental Factors on Ammonia Volatilization from a Urea-Fertilized Soil
Soil Science Society of America Journal - Tập 49 Số 2 - Trang 376-381 - 1985
R. J. B. Bouwmeester, P. L. G. Vlek, J. M. Stumpe
Relations Between Acidic Aluminum and Soil pH, Clay and Organic Matter
Soil Science Society of America Journal - Tập 31 Số 6 - Trang 749-752 - 1967
H. B. Pionke, R. B. Corey
AbstractThe relationships of two measures of acidic Al contained in soil, namely KCl‐exchangeable Al and nonexchangeable acidic Al (pH 4.8N NH4OAc extractable Al minus KCl‐exchangeable Al) with soil pH, clay, and organic matter content were evaluated statistically. Exchangeable Al concentrations were observed to be pr...... hiện toàn bộ
Soil Microbial Dynamics: Short‐ and Long‐Term Effects of Inorganic and Organic Nitrogen
Soil Science Society of America Journal - Tập 58 Số 3 - Trang 801-806 - 1994
Mary F. Fauci, Richard P. Dick
AbstractSoils with minimal long‐term organic inputs typically have reduced biological activity, which has implications for current interests in shifting from inorganic to organic inputs and promoting efficient nutrient cycling in agroecosystems. A greenhouse experiment was conducted to investigate the long‐ and short‐term effects of organic vs. inorganic N on micro...... hiện toàn bộ
Survey of Water‐Extractable Phosphorus in Livestock Manures
Soil Science Society of America Journal - Tập 69 Số 3 - Trang 701-708 - 2005
Peter J. A. Kleinman, Ann Marie Wolf, Andrew N. Sharpley, D. B. Beegle, Lou S. Saporito
Water‐extractable P (WEP) in manure is increasingly used as an environmental indicator as it is correlated with P in runoff from soils recently amended with manure. Little information exists on WEP variability across livestock manures. A survey of 140 livestock manures was conducted to assess trends in WEP (dry weight equivalent) related to livestock types and manure storage. Manure WEP ra...... hiện toàn bộ
Influence of Grass and Agroforestry Buffer Strips on Soil Hydraulic Properties for an Albaqualf
Soil Science Society of America Journal - Tập 69 Số 3 - Trang 893-901 - 2005
Tshepiso Seobi, Stephen H. Anderson, Ranjith P. Udawatta, C. J. Gantzer
Agroforestry production systems have been introduced in temperate regions to improve water quality and diversify farm income. Agroforestry and grass–legume buffer effects on soil hydraulic properties for a Putnam soil (fine, smectitic, mesic Vertic Albaqualf) were evaluated in a corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] waters...... hiện toàn bộ
Revealing the Controls of Soil Water Storage at Different Scales in a Hummocky Landscape
Soil Science Society of America Journal - Tập 75 Số 4 - Trang 1295-1306 - 2011
Asim Biswas, Bingcheng Si
Soil water storage is controlled by topography, soil texture, vegetation, water routing processes, and the depth to the water table. Interactions among these factors may give rise to scale‐dependent nonstationary and nonlinear patterns in soil water storage. The objectives of this study were to identify the dominant scales of variation of nonstationary and nonlinear soil water storage and ...... hiện toàn bộ
Competitive Adsorption of Arsenate and Arsenite on Oxides and Clay Minerals
Soil Science Society of America Journal - Tập 66 Số 2 - Trang 413-421 - 2002
Sabine Goldberg
Arsenic adsorption on amorphous Al and Fe oxides and the clay minerals, kaolinite, montmorillonite, and illite was investigated as a function of solution pH and As redox state, i.e., arsenite [As(III)] and arsenate [As(V)]. Arsenic adsorption experiments were carried out in batch systems to determine adsorption envelopes, amount of As(III), As(V), or both adsorbed as a function of solution...... hiện toàn bộ
Nature and Rates of Selenium Transformations: A Laboratory Study of Kesterson Reservoir Soils
Soil Science Society of America Journal - Tập 60 Số 3 - Trang 791-800 - 1996
P.T. Zawislanski, Mavrik Zavarin
Collapsible Loess in Iowa
Soil Science Society of America Journal - Tập 37 Số 2 - Trang 281-284 - 1973
Richard L. Handy
AbstractThe collapsibility, or tendency towards rapid consolidation or settlement upon saturation by water, of many C‐horizon loess soils constitutes and important physical property pertinent to soil genesis, erosion, and engineering. The potential of a loess soil to collapse upon saturation by water may be established from undisturbed samples saturated while under...... hiện toàn bộ
