Wait for an element to be released empty medium, remain at soil or in entering groundwater and surface water, create serious agricultural area

Source pollution. And have improve fertilizer efficiency, reduce chemical fertilizer to make the dosage, delay that reduces fertilization to wait for an advantage with labour accuses commentate fat

Makings, solving resource excessive use up, reduce agricultural face source pollution, reduce agriculture to produce the respect such as cost to have

Main effect, further progress promotion is imperative. A few experts and generator are mirrorred, our country should develop strong
