New method of fertilization: bag fertilization

The so-called bag method is to put chemical fertilizers into small plastic bags according to the different needs of *** crops for nutrients. Plastic pouches are made of biodegradable materials. There are many small holes in the bag, and over time, it can gradually break and decompose, which can save a lot of fertilizer and labor.

When sowing or transplanting, bury the fertilizer sachets in the soil next to the crops. In this way, in March to June, the chemical fertilizer in the bag is first slowly and continuously released through the small holes, and then as the plastic bag is cracked, a larger amount of fertilizer is dissolved for the crop to absorb and use.
