Potassium cycling in the wheat/corn rotation soil/plant system in Shaanxi

IPNI-1995-CHN-SN2

Potassium cycling in the wheat/corn rotation soil/plant system in Shaanxi, 1995 Available soil K levels are more easily maintained when crop residues are retained on the field to supplement the addition by potash fertilizer. On the high K loess soils of Shaanxi province, no yield benefit for summer corn was realized in 1995 by this management practice. Read more
