Abstract

The range of effective and total zinc contents in the grassy marshland of Sanjiang Plain are calculated from 107 samples. Over one-third of the farm land has contents below the critical value for zinc deficiency categories. Experiments show that the use of zinc fertilizers can raise the yield of wheat and soya bean.
