Crops from sowing to harvest, the absorption of nutrients is relatively fixed, and a certain proportion of various nutrients. Whether it is the excessive use of fertilizers, or the excessive use of a certain nutrient, there is no benefit to the growth of the crops and waste is caused.
Excessive application of fertilizers, especially chemical fertilizers, can cause excessive nutrient concentrations in the soil solution, which is detrimental to seed germination. Excessive nutrient concentrations can burn the seeds, injure the seedlings, and inhibit the growth of the crops, just as crops grow on salinized soils with high salinity. During the crop growing period, over-application of nitrogen fertilizer will cause crops to become leggy, become greedy and late-maturing, prone to lodging and incur pest and disease infestation, eventually leading to an increase in the rate of empty ploughing, a decrease in the weight of one thousand grains, and a decrease in yield. Excessive application of phosphate fertilizer is also detrimental to crop growth. Not only does the vegetative period shorten, the maturation period advances, and premature senescence occurs, but also the lack of nutrients such as zinc, iron, and magnesium easily affects the quality of crops. Excessive application of potash or trace elements is also detrimental to crop growth.
Therefore, fertilizers are not given as much as possible. Applying more is not only a waste but also causes damage to the crop.
