From cropping to harvesting, the nutrients absorbed are relatively fixed, and there is a certain proportion between the various nutrients. Whether it is the total amount of fertilizer too much, or too much a certain amount of nutrients applied to crops grown are no good, and wasteful. Excessive application of fertilizers, especially chemical fertilizers, can result in excessive nutrient concentrations in the soil solution, which is detrimental to seed germination. High nutrient concentrations will burn seed, seedling injury, crop growth was inhibited, just as the same species on the high salinity soil salinization. In the crop growth period, excessive application of nitrogen fertilizer will cause crops to appear lengthy, greedy and late-maturing, easy to fall and incur pests and diseases , eventually leading to an increase in openness, a decrease in 1000-grain weight, and a decrease in yield. Excessive application of phosphate fertilizer is also unfavorable for crop growth. Not only is the vegetative period shortened, the maturity period is advanced, premature aging occurs, and it is easy to cause deficiency of nutrients such as zinc, iron and magnesium , which affects crop quality. Excessive application of potash or trace elements is also unfavorable for crop growth. Therefore, the fertilizer is not applied as much as possible. Shi more, not only a waste, and while the damage to the crops.
