How much chemical fertilizer is applied to one mu of aquaculture water?

Fertilization in aquatic ponds should be based on the fatness of water bodies.

Generally, the poor water is mainly urea, about 5 kg per mu, plus some phosphate fertilizer, about 2 kg per mu.

The water quality and fertility are moderate, with phosphate fertilizer as the main topdressing, generally per mu1~ 2kg.

When the weather is hot, it is not recommended to use urea or ammonium bicarbonate, both of which are easy to cause bacterial bleeding of fish.
