Is it better to fertilize?
In the absence of soil fertility, fertilization according to the needs of the crop, the crop yield will increase accordingly. However, there is no positive correlation between the increase in fertilizer application and the increase in yield. When the fertilizing amount is very low, the increase in the unit fertilizer is large. With the increase of the fertilizer amount, the increment of the unit fertilizer shows a decreasing trend. When the fertilizer amount increases to a certain degree, the production of more fertilizer materials will not increase. . This is the law of diminishing returns. Therefore, the potential for increased fertilization is not unlimited, and fertilization has to be limited. Exceeding this limit means that excessive fertilization will inevitably bring about economic losses. The scientific fertilization is not the better the fertilizer is applied. In layman's terms, it is to achieve "no food is wasted."
