Excessive application of phosphate fertilizer is not only useless, but also harmful. One is the excessive application of phosphate fertilizer, will make the crop absorb excessive phosphorus from the soil nutrition. Too much phosphorus nutrition will promote the crop's respiration to be too strong, and the dry matter consumed will be greater than the accumulated dry matter, which will lead to the premature development of the reproductive organs, cause premature crop maturation, small grains and low yield. The second is to induce zinc deficiency in soil. Excessive application of calcium phosphate will cause zinc in the soil to react with excess phosphorus, produce zinc phosphate precipitation, the crop can not be absorbed, so that the crop appears obvious symptoms of zinc deficiency; excessive use of calcium phosphate, phosphate fertilizer and other alkaline phosphate fertilizer, will make the soil alkali As a result, the effectiveness of zinc is reduced, which affects the absorption of zinc by crops. Third, over-application of phosphorus will make the crop lose phosphorus and lose silicon. According to the study, excessive application of P fertilizer will also cause the silicon in the soil to be fixed and unable to be absorbed, causing crops to suffer from silicon deficiency, and in particular to silicon-based grass crops. Fourth, over-application of phosphorus will result in phosphorus deficiency in crops. Appropriate application of phosphate fertilizer will promote the absorption of molybdenum by crops, but excessive application of phosphate fertilizer will cause phosphorus and molybdenum to lose their nutrient balance, affect the absorption of molybdenum by crops, and show "molybdenum deficiency."
