Role and Uses of Agricultural Potassium Nitrate

2024-06-25

Potassium nitrate not only has high potassium content, but also is nitrogen-potassium compound fertilizer with good water solubility and low acidity of solution, which is easy to be absorbed by plants, and is suitable for any crops and any seasons with broad-spectrum applicability. It can be used as N fertilizer and K fertilizer; it can promote each other to be absorbed by the crops and promote the absorption of other nutrients (calcium, magnesium), and the effect of fertilizer is rapid.

Advantages:

(1)Improvement of yield: provide sufficient potassium fertilizer for good growth of crops, significantly improve photosynthesis and yield of crops, yield generally increased by more than 20%.

(2)Improve the quality: it can make the fruits color brightly, expand fast, fruit shape positive, increase the sugar content of fruits, taste pure and sweet.

(3) Enhance disease resistance: the best anti-stress fertilizer, improve crop resistance to disease, pest, drought and salt damage.

Mainly used in fireworks, black powder, matches, fuse, candle wicks, tobacco, color TV picture tubes, drugs, chemical reagents, catalysts, ceramic glaze, glass, fertilizers, and foliar spray fertilizers for flowers, vegetables, fruit trees and other cash crops. In addition, potassium nitrate is used as auxiliary material in metallurgical industry and food industry.

It is mainly used in picture tube glass shells, automobile lamp glass shells, glass clarifier. Used as compound fertilizer for crops and flowers, foliar spray fertilizer. Used in fireworks to produce purple sparks. It is the raw material for making black gunpowder, such as mine gunpowder, fuse, firecracker and so on. Used in the pharmaceutical industry for the production of penicillin potassium salt, rifampicin and other drugs. Used to make cigarette paper. Used as catalyst and mineral processing agent. Ceramic industry used to manufacture ceramic glaze. Heat treatment salt bath. Potassium nitrate is used as a coloring agent in the food industry; preservative, e.g. for cured meat, in luncheon meat to play a preservative role.
