Organic fertilizers are mainly applied to soil from plants and/or animals, providing a source of plant nutrition for the main function of carbon materials.

Although there are various types of organic fertilizers, there are relatively small amounts of nutrients such as bacteria. Mature bacteria that need to be stored and used in conjunction with chemical fertilizers for better results. With the continuous development of science and technology, various types of bio organic fertilizers can be produced through the artificial screening, isolation, domestication and cultivation techniques of beneficial bacterial communities. Organic fertilizers that have undergone harmless treatment of beneficial bacteria can improve soil quality, reduce environmental pollution, and enhance fertilization efficiency. Organic fertilizer equipment manufacturers are certified organic agricultural organic fertilizers that comply with certification bodies and meet the standards for producing organic products. In recent years, the rapid development of various biological fertilizers has led to an annual output of several tens of tons. These higher-level biological fertilizer technologies have a positive significance in improving soil fertility, increasing crop yield, improving crop quality, and effectively implementing sustainable agricultural development, with increasing yield and environmental pollution as their main functions in production, promotion, and application. We believe that more information on the production, product quality, and issues related to the use of bio fertilizers is essential to improve rural awareness of these fertilizers, promote their accurate and scientific use, and promote the healthy development of bio fertilizers in China.
