Title: Study on Fertilizer Efficiency of Several New Types Urea in Huaibei Vertisol.
Abstract: By way of field experiments of new types urea and ordinary urea on wheat and maize two years respectively, obtained a result:new type urea of applying as base fertilizer were able to improve not only crop yield, but also fertilizer utilization efficiency. On wheat and maize, they increased yield 9.55% and 18.75% respectively, improved fertilizer utiolization efficiency 1.6%-12.6% and 4.1%-16.4% respectively. Economic benefits showed a marked increase. They displayed preliminarily a characteristic of long fertilizer efficiency and a good effect of increasing crop yield.
