Sandy sand has high sand content, good permeability, rapid soil temperature change, low nutrient content, and poor fertilizer retention. Therefore, when applying fertilizers, it is necessary to have a reasonable method of fertilization so as to prevent premature aging of the crop due to lack of fertilizer. When applying fertilizers, the following points should be noted:
First, the sandy soil has low organic matter content and organic fertilizer should be added to increase soil organic matter content.
Secondly, it is advisable to use cold manure such as cow dung or semi-ripe organic manure as base fertilizer in order to increase soil fertility and water storage capacity.
Third, top-dressing grasps the principle of â€œfew timesâ€ to reduce nutrient losses and increase fertilizer utilization.
Fourth, nitrogen fertilizer should be added in the late stage of crop growth to prevent premature yield loss due to crop failure.
