Notes on organic fertilizer
1. Organic fertilizer should be combined with water-soluble fertilizer.
Organic fertilizer decomposition is slow, fertilizer efficiency is late, so we must pay attention to fertilization, to complement each other, reasonable collocation.
2. Organic fertilizer should be fully decomposed.
Most organic fertilizers often contain bacteria, insect eggs and weed seeds. Therefore, the compost windrow turner adds insecticides and fungicides such as zinc, sulfur and phosphorus to the organic fertilizer after composting and fermentation.
However, if the manure is not decomposed directly into the soil, the phenomenon of seed burning and seedling burning can occur. At the same time, organic fertilizer contains a lot of insect eggs and bacteria, which will cause serious damage to crops if it is not decomposed.
4、 Stacking period
During spring, summer and autumn, the outdoor temperature was kept above 20 ℃.
5、 Site selection
For composting by organic fertilizer machine fermentation, open land with sunny, slightly higher terrain, favorable drainage and convenient transportation should be selected.
