Effect of fertilizer, legumes and cropping frequency on soil organic matter in a long-term rotation – changes after 6 years of zero tillage
Campbell, C.A.; Lafond, G.P.; Selles, F.; McConkey, B.G.; Hahn, D.; Wen, G. (1997-02-20)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 ... -
The effect of N fertilizer placement, formulation, timing, and rate on the agronomic performance in wheat
Wang, H.; Lemke, R.; Hahn, D.L. (2003-02-18)Increasing the efficiency of nitrogen fertilizer uptake by crops improves the agronomic, economic, and environmental value of fertilizer N. Band placement of urea below the soil surface increased recovery of N in plants ... -
