Soil enzymatic factors expressing the influence of land use, tillage system and texture on soil biochemical quality
Canadian Journal of Soil Science - Tập 80 Số 3 - Trang 419-428 - 2000
Carlos M. Monreal, D. W. Bergstrom
We identified complexes of soil nutrient mineralising enzymes expressing the influence of land use, tillage system and texture on soil biochemical quality in production systems involving corn, soybean, wheat and oat. The activities of dehydrogenase, β-glucosidase, L-glutaminase, urease, alkaline phosphatase, and arylsulphatase were measured in 760 soil samples taken from the A horizon of ...... hiện toàn bộ
Nitrogen availability for corn in soils amended with urea, cattle slurry, and solid and composted manures
Canadian Journal of Soil Science - Tập 73 Số 2 - Trang 253-266 - 1993
J. W. Paul, E. G. Beauchamp
This study was conducted to determine whether manure N availability for corn (Zea mays L.) was best estimated by a component of the manure N or by soil inorganic N in May or June. Liquid dairy cattle manure, solid beef cattle manure, and composted beef cattle manure were applied in the spring of 1988, 1989 and 1990 at rates of 100, 200 and 300 kg N ha−1. Urea was appl...... hiện toàn bộ
Comparison of soil-to-water suspension ratios for determining electrical conductivity of oil-production-water-contaminated soils
Canadian Journal of Soil Science - Tập 96 Số 2 - Trang 233-243 - 2016
Aaron W. Klaustermeier, Hannah Angie Kelsey Tomlinson, Aaron Lee M. Daigh, Ryan F. Limb, Thomas M. DeSutter, Kevin K. Sedivec
Soil salinity caused by oil-production-water (brine) contamination is a major issue in regions of oil and gas development. However, rapid site assessment tools such as soil-to-water suspension electrical conductivity (EC) methods and conversion equations have not been previously calibrated and validated for brine-contaminated soils. Our objective was to compare three soil EC methods and d...... hiện toàn bộ
Economics of reduced tillage fallow-crop systems in the Dark Brown soil zone of Alberta
Canadian Journal of Soil Science - Tập 76 Số 3 - Trang 411-416 - 1996
Elwin G. Smith, Robert E. Blackshaw, C. W. Lindwall, Francis J. Larney, T. L. Peters
The use of conservation tillage management in fallow cropping systems reduces soil erosion and improves soil quality. The economic benefits of these alternate tillage methods are less certain. This study examined the economic returns from reduced tillage methods on fallow using yield and input data from two experiments at the Agriculture and Agri-Food Canada Research Centre at Lethbridge,...... hiện toàn bộ
Pelletized organo-mineral fertilizer product as a nitrogen source for potato production
Canadian Journal of Soil Science - Tập 85 Số 3 - Trang 387-395 - 2005
Bernie J. Zebarth, R. Chabot, J. Coulombe, R. R. Simard, J. Douheret, Nicolas Tremblay
Replacement of mineral fertilizer with organo-mineral fertilizer products made with animal manures is one strategy for reducing the environmental impact of agricultural production. This study evaluated a pelletized organo-mineral fertilizer product with a nutrient analysis of approximately 7-4-4 produced from composted solid poultry, solid dairy and liquid hog manure as a N source for pro...... hiện toàn bộ
Impact of potato-cereal rotations and slurry applications on nitrate leaching and nitrogen balance in sandy soils
Canadian Journal of Soil Science - Tập 82 Số 4 - Trang 469-479 - 2002
Marc‐Olivier Gasser, M. R. Laverdière, Réal Lagacé, Jean‐François Caron
Groundwater quality is at risk when high levels of N fertilizers are used on sandy soils. A monitoring program was initiated in the summer of 1995, to quantify nitrate leaching in sandy soils used for potato production near Quebec city, Canada. Three drainable lysimeters were installed in each of five fields, for a total of 15 lysimeters. During a 5-yr monitoring period, crop N uptake, mi...... hiện toàn bộ
Influence of biosolids and fertilizer amendments on physical, chemical and microbiological properties of copper mine tailings
Canadian Journal of Soil Science - Tập 90 Số 4 - Trang 571-583 - 2010
Wendy C. Gardner, Klaas Broersma, M. Anne Naeth, D. S. Chanasyk, A. Jobson
A 3-yr field study was conducted on two texturally different tailings sites at the Highland Valley Copper Partnership mine in south-central British Columbia to determine the effects of fertilizer and biosolids amendments on selected soil physical, chemical and microbiological properties. Soil bulk density and penetration resistance decreased in the upper 15 cm of tailings with increasing ...... hiện toàn bộ
Quality and dynamics of soil organic matter in a typical Chernozem of Ukraine under different long-term tillage systems
Canadian Journal of Soil Science - Tập 92 Số 3 - Trang 429-438 - 2012
Yuriy Kravchenko, Natalia Rogovska, Lyudmila Petrenko, X. Zhang, Changchun Song, Yi Chen
Kravchenko, Y., Rogovska, N., Petrenko, L., Zhang, X., Song, C. and Chen, Y. 2012. Quality and dynamics of soil organic matter in a typical Chernozem of Ukraine under different long-term tillage systems. Can. J. Soil Sci. 92: 429–438. Tillage has been reported to induce changes in soil organic matter (SOM) concentrations and quality. Conversion of plow-tillage to minimum till and no-till (...... hiện toàn bộ
METHOD OF REPEATED ADDITIONS FOR GENERATING PESTICIDE ADSORPTION-DESORPTION ISOTHERM DATA
Canadian Journal of Soil Science - Tập 59 Số 4 - Trang 435-437 - 1979
B. T. Bowman
An improved method is suggested for obtaining desorption isotherm data, which avoids problems associated with decanting supernatant solutions. This technique is also useful in obtaining adsorption isotherm data at equilibrium concentrations approaching the solubility limit of the absorbate.
Effect of nitrogen fertilizer application on seed yield, N uptake, and seed quality of Camelina sativa
Canadian Journal of Soil Science - Tập 94 Số 1 - Trang 35-47 - 2014
S. S. Malhi, Eric N. Johnson, Linda M. Hall, William E. May, S. Phelps, B. Nybo
