Effect of fertilizer, legumes and cropping frequency on soil organic matter in a long-term rotation – changes after 6 years of zero tillage
Society is interested in methods of increasing C storage in soil, so as to reduce CO, concentration in the atmosphere, which may contribute to Global warming. Scientists have demonstrated that the adoption of better ...
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 ...
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 ...
