A field experiment was conducted to study the effects of different ratios of controlled-release nitrogen in bulk blend fertilizers and N application modes on soil available nutrition contents
P
K fertilizer use efficiency.The results showed that the release of the 52.5% ratio of controlled-release bulk blend fertilizers in basal application mode accorded with requirement of maize better than the other treatments.Compared with the other applied fertilizers treatments
