How to Apply Organic Fertilizer

Some people blame the soil deterioration on the excessive application of chemical fertilizers, and then believe that more organic fertilizers can improve crop yield and quality, and can nourish and fertilize the land. Therefore, in recent years, many vegetable farmers have spared no effort to increase the application of organic fertilizer, some vegetable farmers 1 mu shed chicken manure is up to 40 cubic meters. I do not know, excessive application of organic fertilizer will also affect the physical and chemical properties of the soil, serious will make the soil salt accumulation, affecting crop growth. And excessive application of organic fertilizer will also lead to the accumulation of nitrate in the body of vegetables, does not meet the requirements of standardized vegetable production. In the application of organic fertilizer should pay attention to the following points.

1. Pay Attention to the Choice of High-Quality Organic Fertilizer
High-quality organic fertilizer is the basis for high yield of vegetables, and now vegetable farmers apply organic fertilizer, mostly bought commercial organic fertilizer, the quality is generally poor, some even mixed with urban sludge, household waste, etc., simply can not meet the standards of organic matter content. Even some bought chicken manure, there are many adulterated with soil, or by some unscrupulous traders mixed with fire alkali (for increasing the volume), these poor quality organic fertilizer applied to the soil, the effect can be imagined. Therefore, the production must use high quality organic fertilizer, the best choice of commercial organic fertilizer produced by a large regular factory.

2. Strictly Control the Amount of Fertilizer
 In general, each mu of vegetable land to apply pure chicken manure 15-20 cubic meters, 35-40 cubic meters of rice husk manure is appropriate. Eggplant and fruit vegetables need more fertilizer, can take its upper limit; leafy vegetables need a little less fertilizer, can take its lower limit.

3. With Biological Fertilizer Application Effect is Good
With organic fertilizer regardless of the base application and wash application, it is best to apply with biological fertilizer. Because organic fertilizer in conjunction with biological fertilizer application, biological fertilizer in the biological bacteria can accelerate the decomposition of organic matter in organic fertilizer, so that it is more conducive to crop absorption, while some harmful substances in organic fertilizer decomposition transformation, to avoid its harm to vegetables.
