In field trials, recovery of basal N application of 60-70 kg/ha was 43% at Takadate on soil which had a higher cation exchange capacity than that at Odawara where recovery was 27%. Soil N uptake at ear emergence was 71 kg/ha on soil which gave greater mineralization of N than the soil at Takadate where soil N uptake was 44 kg/ha. Residual basal N was 16% at Takadate and 19% at Odawara.
