Effect of soil moisture and soil organic matter on soil bulk density during a growing season
We measured surface (0-7.5 cm) soil bulk densities at nine sampling times for two and four long-term crop rotations at Swift Current and Indian Head respectively, to determine the effect of crop management and time. In a ...
Interpreting potential plant availabitily of N based on soil supply indicies
Soil supply of nitrogen is the most intensively studied of all nutrient cycles. Prior to the widespread use of fertilizers, economically viable agriculture was dependent solely on the soils ability to supply N. From 1945 ...
Effect of tillage on selected soil biochemical characteristics in a coarse- and medium-textured soil in southwestern Saskatchewan
Characterization of soil organic matter is valuable for identifying the overall quality of soils. Crop management will influence soil quality. Some changes may become apparent more quickly than others and may depend upon ...
Relationship between mineralizable N and hot KCl extractable NH4-N – variability at one site
To characterize the N supplying capacity of the soil at a site where a new long-term experiment was being initiated at Scott, Saskatchewan, we soil sampled the site in a systematic manner, taking 160 cores. We used these ...
Split nitrogen applications for management of yield and protein of wheat grown in dryland
The feasibility of using split-N applications for managing yield and protein of wheat grown on dryland was studied in a field experiment initiated on a sandy loam and silt loam near Swift Current. Spring wheat was grown ...
Straw removal and fertilization on grain yields and soil organic matter in a fallow-wheat-wheat rotation
There is considerable interest being shown in the harvest and use of straw for industrial purposes in Manitoba and Alberta. In 1987 we measured soil C and N in a 30-year crop rotation experiment at Indian Head. Results at ...
