History of fertilizer
History of fertilizer

In 70s of last century before the widespread use of rural primary fertilizer. As the organic fertilizer in some elements (such as nitrogen, phosphorus and potassium) content can not fully meet the lawn and crop needs, therefore lower yield. In order to improve lawn and crop yield, we must increase the amount of fertilizer application rate. According to statistics, nitrogen organic fertilizer can provide only 30% of crop nitrogen requirements, 70% rely on chemical fertilizer supply, the other, such as phosphorus, potassium and other elements also show similar fertilizations resulting, yield very significant. For this reason, some farmers began to ignore the application of organic fertilizer, application of fertilization rate decreased through out the year, and even individual orchard application of organic fertilizer is no longer alone, application of chemical fertilizers to maintain production, resulting in soil compaction, decline in crop productivity and quality.

Production of organic fertilizer in the role of crop can not be replaced. First, rich in nutrients contained, comprehensive, and is any kind of fertilizer not available; second, to improve the soil; Third, it helps promote soil microbial activity, accelerating the process of soil biological, macro, is conducive to lawn, crop and fruit trees growth and development; fourth during the decomposition of organic fertilizers can produce large amounts of organic acids, can make some insoluble nutrients into soluble nutrients, thereby enhancing the utilization of soil nutrients. Therefore, we must attach importance to the application of organic fertilizer on the crop. The amount of organic fertilizer and lawn, crop and fruit trees generally require equal application or the times of production facilities into.
