What is the effect of organic fertilizer on rice? How much is one mu of land?

Organic fertilizer can not only provide comprehensive nutrition for crops, but also has a long fertilizer effect. It is the main nutrient for green food production.

Next, let's understand together.

What effect does organic fertilizer have on rice?

1. Organic fertilizer raw material source wide, can be local materials, local production system, only spend time, do not need to invest much money, can save fertilizer, reduce production costs.

How to identify organic fertilizer?
