Agricultural waste transformed into soil remediation

The “Bioorganic Fertilizers to Overcome Soil Biological Obstacles and Their New Processes” researched by Professor Shen Qirong and his team at Nanjing Agricultural University have succeeded in transforming China’s annual agricultural waste into a microbial organic fertilizer capable of overcoming the continuous biological obstacles in the soil. , and get large-scale demonstration, promotion and application.

It is understood that agricultural waste is also called agricultural waste, which mainly includes plant fibrous waste and livestock and poultry excrement. As long as timely and effective treatment is performed, the use of agricultural waste is very promising.

According to reports, this process is mainly to study and screen functional microorganisms that antagonize soil-borne pathogens, high-efficiency-secretases, and high-efficiency composts, invented a step-by-step fermentation technology and process for secondary solidification of microbial organic fertilizers, and bio-supply of amino acid raw materials in microbial organic fertilizers. And so on, it can ecologically repair the "destroyed" soil of pesticides. The process has been extensively demonstrated, promoted and applied in 24 provinces, municipalities and autonomous regions, with a total area of ​​more than 2000 million mu. Among them, the establishment of a technical extension service center in Hainan, in the establishment of 500,000 acres of banana demonstration area, after three consecutive years of bioremediation and prevention and control, the incidence of field blocks from the original 30% to 7.5%.
