Four Points Of Agriculture Organic Fertilizer Application

Organic fertilizers are mainly human and animal manure, crop straws, and green manure. There are many types of organic fertilizers with different functions. When applying them, pay attention to science and avoid blind application.

Increase Nutrient Content

There are many types of nutrients in organic fertilizers, but the nutrient content is low, and the decomposition in the soil is slow. When the amount of organic fertilizers is not large, it is difficult to meet the needs of crops for nutrients. The fertilizer has high nutrient content and rapid fertilizer effect, and can be supplemented according to the amount of crops required, but the fertilizer effect period is short. In order to obtain high yields, organic fertilizers and chemical fertilizers should be applied in combination, complementing each other's strengths, giving full play to their respective advantages, and meeting the needs of crops for various nutrients in terms of quantity and time.

Ensure Nutrient Balance

Compared with chemical fertilizers with relatively single nutrients, organic fertilizers have the advantage of containing more types of nutrients, but the nutrients they contain are not balanced and cannot fully meet the needs of high yield and quality of crops. When applying organic fertilizers, chemical fertilizers should be applied according to the requirements of crops for nutrients. Even farmland producing green foods should be applied with appropriate amounts of mineral fertilizers, and various foliar fertilizers should be applied during crop growth.

Need To Undergo Fermentation

Many organic fertilizers carry germs, eggs, and weed seeds. Some organic fertilizers contain organic compounds that are not conducive to crop growth. Therefore, they should be applied after stacking fermentation and processing. Raw manure cannot enter the ground.

Contraindications To Organic Fertilizer Application

The fully decomposed organic fertilizer should not be mixed with alkaline fertilizer to avoid ammonia volatilization and reduce the nutrient content of organic fertilizer. Organic fertilizer contains more organic matter, so it is not suitable to mix with nitrogenous fertilizer.
