Calcium nitrate decahydrate is a common chemical substance widely used in fertilizers, pharmaceuticals, food additives and other fields. In agricultural production, Calcium nitrate decahydrate is widely used for soil improvement and plant growth regulation.

1. Usage of Calcium nitrate decahydrate

①Fertilizer time:

The best time to fertilize Calcium nitrate decahydrate is at different stages of crop growth, and the best effect is achieved at the early and middle stages of growth. Generally speaking, it is suitable to fertilize in the period of crop fertilizer, such as early autumn, late autumn and so on.

②Fertilizer amount:

The fertilizer amount of Calcium nitrate decahydrate should be adjusted according to the needs of different regions and crops. Generally speaking, applying 10-20kg of calcium nitrate decahydrate per mu can effectively improve crop yield and quality.

③Fertilization mode:

Calcium nitrate decahydrate can be fertilized by spreading or irrigation. When spreading, the calcium nitrate decahydrate should be. Calcium nitrate decahydrate evenly spread on the land, and then gently plow up with a rake or hoe to make it mix with the soil. The fertilizer should be spread evenly over the land.

①Wear protective gear such as gloves, masks and protective goggles during operation to avoid inhalation or contact with calcium nitrate decahydrate, which may cause injury.

②The amount of fertilizer should be controlled, too much fertilizer will lead to soil acidification, affecting plant growth and yield.

③Calcium nitrate decahydrate package should be labeled with information such as ingredients, production date and expiration date to avoid using expired fertilizers.

④If too much calcium nitrate decahydrate is applied, the residual fertilizer should be cleaned up in time, the package should be collected and kept away from fire and high temperature environment.
