How to prolong the effective period of water-soluble fertilizer? This is a question in the hearts of some farmers' friends. According to Xiaobian, under normal circumstances, the effective period of water-soluble fertilizer is probably20arrive25About days, because water-soluble fertilizer can quickly dissolve and take effect quickly, it can be directly absorbed and utilized by the roots of crops when it is directly applied into the soil. So is there any way to extend it? What about the effective period of water-soluble fertilizer?

1.The dosage should be appropriate, not as much as possible. Water-soluble fertilizer has a high content of nitrogen, phosphorus and potassium, and the standard is50%Therefore, the amount used is less than others, and the basic usage amount of one acre of land is similar.5kgYes, it can be used during the peak period of fertilizer demand or when the number of fruits is relatively large.8kgarrive10kgUsually, a small amount of fertilizer can be used several times to avoid fertilizer loss.

2.Water-soluble fertilizer can be used by itself or together with other fertilizers, but it can not be mixed with alkaline pesticides, especially when spraying on leaves, the metal ions on leaves react and cause precipitation, causing fertilizer damage or phytotoxicity of leaves.

3.Use the secondary dilution method, and don't apply it directly. If water-soluble fertilizer is used directly without dilution, it is easy to cause the local concentration of roots to be too high, which will lead to the phenomenon of seedling burning. The secondary dilution can ensure the uniform fertilization and improve the utilization rate of fertilizer.
