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

Rapid Measurement of Soil pH Buffering Capacity
Soil Science Society of America Journal - Tập 76 Số 2 - Trang 694-699 - 2012
D. E. Kissel, Leticia Sonon, M. L. Cabrera
Equations for Predicting Soil Organic Carbon Using Loss‐on‐Ignition for North Central U.S. Soils
Soil Science Society of America Journal - Tập 66 Số 6 - Trang 1878-1881 - 2002
Michael E. Konen, Peter Martin Jacobs, C. Lee Burras, Brandi J. Talaga, Joseph A. Mason
Samples of 255 noncalcareous A, Ap, and AB horizons from selected major land resource areas (MLRA) in the north central USA were used to develop equations for predicting organic C content, as determined with a Leco C analyzer, from weight loss‐on‐ignition (LOI). Organic C concentrations of the samples ranged from 1.09 to 114.6 g kg−1 Within each MLRA, strong linear rel...... hiện toàn bộ
Aggregation and Soil Organic Matter Accumulation in Cultivated and Native Grassland Soils
Soil Science Society of America Journal - Tập 62 Số 5 - Trang 1367-1377 - 1998
Johan Six, Edward T. Elliott, Keith Paustian, John W. Doran
AbstractTillage intensity affects soil structure and the loss of soil organic C and N. We hypothesized that no‐tillage (NT) and conventional tillage (CT) differentially affect three physically defined particulate organic matter (POM) fractions. A grassland‐derived Haplustoll was separated into aggregates by wet sieving. Free light fraction (LF) and intra‐aggregate ...... hiện toàn bộ
Relating Extractable Soil Phosphorus to Phosphorus Losses in Runoff
Soil Science Society of America Journal - Tập 60 Số 3 - Trang 855-859 - 1996
D. H. Pote, T. C. Daniel, P. A. Moore, D. J. Nichols, Andrew N. Sharpley, D. R. Edwards
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
Long‐Term Effects of Tillage and Fertilization on Soil Organic Matter Dynamics
Soil Science Society of America Journal - Tập 61 Số 1 - Trang 152-159 - 1997
J. R. Salinas-García, Frank M. Hons, J. E. Matocha
AbstractUnderstanding the effects of long‐term management practices on soil C and N pools and activities is essential for sustaining soil productivity. The objectives of this study were to evaluate long‐term and seasonal changes in soil organic C (SOC), soil microbial biomass C (SMBC) and N (SMBN), and mineralizable C and N in continuous corn (Zea mays...... 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
Effects of Cover Crops on Soil Aggregate Stability, Total Organic Carbon, and Polysaccharides
Soil Science Society of America Journal - Tập 69 Số 6 - Trang 2041-2048 - 2005
Aiguo Liu, B. L., A. A. Bomke
Structural degradation of silt clay loam soils in Delta, British Columbia, has resulted from intensive cultivation of vegetable crops. A field experiment and a laboratory incubation study were conducted to assess the ability of nonleguminous winter cover crops, spring barley (Hordeum vulgare L.), fall rye (Secale cereale L.), and annual...... hiện toàn bộ
