Notes on the use of organic fertilizers

In use, the choice of organic fertilizer is undoubtedly the most important, but also need to pay attention to the following points.

1. organic fertilizer nutrients are not balanced, nitrogen, phosphorus and potassium content is low, and slow decomposition in the soil, although the variety of nutrients, but not as much as the nutrients single chemical fertilizer can not meet the needs of high yield and quality crops. In the application of organic fertilizer should be applied according to the crop requirements for nutrients with chemical fertilizers, organic fertilizers and chemical fertilizers with the application of the strengths and weaknesses of each, to play their respective advantages in the number and time to meet the needs of crops for various nutrients. Even the production of green food farmland should also be dispensed with the appropriate amount of mineral fertilizer, and in conjunction with the spraying of sea elf (biostimulant) quality foliar fertilizer during the growth of crops to ensure that the crop nutrient needs.

2. Organic fertilizers should not be mixed with alkaline fertilizers, so as not to cause the volatilization of ammonia and reduce the nutrient content of organic fertilizers. Organic fertilizer contains more organic matter, also should not be mixed with nitrate nitrogen fertilizer.

3. Do not overuse organic fertilizer. Excessive use of organic fertilizers can lead to the following situations: burning seedlings, resulting in a large number of nutrients such as phosphorus and potassium in the soil, resulting in soil nutrient imbalance; nitrate ion concentration in the soil, resulting in excessive nitrate salt in crops, high soil solution concentration, which is not conducive to root water absorption.
