How to operate fertigation?

Fertilizer dissolution and mixing

When the liquid fertilizer is applied, there is no need to stir or mix. Generally, the solid fertilizer needs to be mixed with water to form a liquid fertilizer, and if necessary, separated to avoid precipitation and the like.

Fertilization control

The dose should be mastered when fertilizing, and the appropriate concentration for injecting the fertilizer is about 0.1% of the irrigation flow . For example, the irrigation flow rate is 50 cubic meters per mu, and the injected fertilizer solution is about 50 liters / mu; excessive application may cause crop death and environmental pollution.
