The main cause of pesticide residues is the application of a large amount of fertilizer. Nutrients such as nitrates and heavy metals are produced in vegetables. At the same time, soil compaction and depletion of soil are caused, and pests and diseases are becoming more and more serious. The continuous use of pesticides causes serious pesticide residues in soil and agricultural products, and the resistance of pathogenic bacteria is also strengthened. The pathogens in the soil are accumulating and growing, causing widespread pests and diseases. Therefore, the amount of pesticides is getting larger and larger, the toxicity is getting higher and higher, and the pesticide residues are getting more and more serious.
Experts in the industry believe that the use of biological fertilizers is one of the most feasible and effective methods for solving pesticide residues. It not only has good fertilizer efficiency, but also reduces harmful residues such as nitrates and heavy metals caused by the use of chemical fertilizers in agricultural products, inhibits and kills pathogenic bacteria and pests, and thoroughly disinfects the soil. Only by eliminating the pathogens in the soil environment well can we fundamentally reduce pests and diseases, and then reduce the use of pesticides or pesticides, thus completely eliminating pesticide residues.
In addition, biological fertilizers, especially bio-organic fertilizers, have the following advantages:
- First, it is efficient, long-lasting, and non-polluting. Bio-fertilizer is a biological preparation made by biotechnology, which has specific fertilizer effects, such as active microorganisms, microbial metabolites and their transformants, which can play a very good fertilizer effect. Its core It is a beneficial active microorganism that is harmless to humans, livestock and crops.
- The second is to improve the soil, promote the formation of agglomerate structure, automatically balance the soil pH, and have a good effect on the transformation of desertified land and saline-alkali land.
- The third is to save energy and protect the environment. Some of the raw materials for bio-fertilizers are some discarded animal manure and crop straw, which can turn waste into treasure, save a lot of energy and eliminate two major sources of pollution.
