Application:
Agricultural potassium nitrate is one of the important members of modern agricultural fertilizers, which overcomes various drawbacks of traditional fertilizers and is an ideal fertilizer for high value-added economic crops such as tobacco, fruits, vegetables, flowers, etc. It belongs to high concentration nitrogen and potassium binary compound fertilizer. Containing 100% plant nutrients, fully soluble in water, the nutrients do not require transformation and can be directly absorbed by crops, promoting early seedling development, increasing yield, and playing an important role in improving crop quality.
