Sand land "eat less meals" Sand soil fertility is poor, easy to lose nutrients, but the sand has good permeability, good for the fertilizer, fertilization after seeing fast effect, fertility but short, no stamina, "do not send hair seedlings Old seedlings." Sand fertilizer application should be "eat less meals," a small amount of time, or with organic fertilizer application. Clay clay has strong fertilizer retention properties, and nutrients are not easy to lose. However, after fertilization, the fertilizer effect is slow, the fertility is long, the soil is tight, and the permeability is poor. It is also difficult for the crops to take root. “Old seedlings do not grow seedlingsâ€. Fertilization pay attention to the concentrated application of phosphate fertilizer and potassium fertilizer, total nitrogen control to prevent late-maturing greediness. The insufficient supply of soil moisture in upland dryland hinders the transfer of nutrients to the root surface in soil solution, affecting the absorption and utilization of nutrients by crops. The principle of fertilization is to apply organic fertilizer in an appropriate amount, increase the structure of soil pellets, improve the permeability of the soil, and make the size of the soil fit properly. If using chemical fertilizers, compound fertilizer containing humic acid should be selected to achieve the purpose of improving the soil.
