The importance of popularizing organic fertilizer
With the gradual attention of the state to environmental protection in recent years, organic fertilizer has gradually entered the people's vision, so what are the benefits of using bio organic fertilizer? Today, organic fertilizer production line plant will introduce the importance of promoting the use of organic fertilizer
As we all know, fertilizer is the food of plants, fertilization is an important means to ensure high and stable yield of crops in agricultural production. In particular, China is the largest country of fertilizer production and consumption in the world, and the use of chemical fertilizer is very large. Although the yield of crops has been increased in a certain period of time and to a certain extent, the harm to soil, water source, agricultural products and environment is increasing day by day, such as soil acidification, hardening, nutrient imbalance, groundwater pollution, excessive heavy metal and nitrate content in agricultural products, etc Ecological environment pollution and human diseases. Due to the heavy and indiscriminate application of chemical fertilizers and the neglect of the application of organic fertilizers, the soil organic matter is deficient, resulting in the decline of soil fertility, which has become an important limiting factor affecting the sustainable development of agriculture and the stable and high yield of crops. The organic fertilizer production plant cost is about 350000 to 500000 yuan.
Due to years of incorrect fertilization has caused irreversible damage to my soil, the only way to improve the soil is to gradually promote the use of bio organic fertilizer. According to the survey and statistics, about 80% of China's agricultural cultivated land is lack of nitrogen, 50% of phosphorus, 30% of potassium, and some soil organic matter is less than 1%. However, organic manure usually contains more than 45% organic matter, more than 2.5% nitrogen and more than 2% phosphorus, and also contains various trace elements. It is not only a good fertilizer source, but also an excellent soil conditioner.
Therefore, the organic fertilizer production process vigorously promote organic fertilizer is the inevitable way to achieve sustainable development of Agricultural Science in the future.
