Applying Organic Fertilizer Scientifically to Prevent Soil Deterioration

People have always blamed the deterioration of soils for excessive use of chemical fertilizers. It is believed that applying more organic fertilizer can increase the yield and quality of crops, and can also provide land for fertilizers. Therefore, in recent years, many vegetable farmers have invested heavily in organic fertilizer, and some vegetable farmers have applied chicken manure to an area of ​​40 cubic meters or more. As everyone knows, excessive application of organic fertilizer will also affect the physicochemical properties of soil, in serious cases will lead to a series of adverse consequences, such as soil salt accumulation, affecting crop growth.

So, how to use organic fertilizer is scientific and reasonable? The author believes that the following points should be noted:

First, pay attention to the selection of high-quality organic fertilizer. High-quality organic fertilizer is the basis for high-quality and high-yield crops. Nowadays, the organic fertilizers used by farmers are mostly purchased commodity fertilizers, and their quality is generally low. Some of them are even doped with municipal sludge and household waste. The standard for organic matter content. Even some of the chicken manure purchased has been soiled with a lot of mud or mixed by some unscrupulous traders to increase the volume. The effect of these inferior organic manures on the soil can be imagined. Therefore, high-quality organic fertilizer must be used in production, and it is best to use formal large-scale manufacturers when choosing commodity organic fertilizer.

Second, fully cooked fermentation after the application. Organic bio-fertilizers can activate soils, improve soils, increase crop disease resistance, insect resistance and resilience, and improve crop quality and yield. However, organic fertilizers such as poultry pens, manure and animal manure, and cakes and pans in the natural world must be fully decomposed and fermented prior to application. After fermentation, firstly, the acidity of the organic fertilizer is balanced, the nitrate content is reduced, and the water is added, which is beneficial to the combined application of the microorganisms in the soil in the natural world; and secondly, the parasite eggs in the original manure can be destroyed after fermentation, and harmful Biological bacteria and other pathogens and hazards directly to crops and soil.

Third, with the application of biological fertilizer effect is good. Organic fertilizers are best used with biological fertilizers, whether they are basic or flushing. Why do you need to use biological fertilizer? Because organic fertilizers are combined with biological fertilizers, biological bacteria in biological fertilizers can accelerate the decomposition of organic matter in organic fertilizers, making them more conducive to crop absorption.
