1. Organic matter content: The content of organic matter in organic fertilizer produced by organic fertilizer equipment is an important indicator to measure the quality of organic fertilizer. In general, the higher the organic matter content of organic fertilizer, the better the fertilizer effect.
2. Total nutrients: The total nutrients in organic fertilizers include nitrogen, phosphorus, potassium and other elements. According to Chinese standards, the total nutrient content of organic fertilizer should not be less than 5%.
3. pH (pH) : pH has a great impact on soil fertility and plant growth. In general, the pH value of organic fertilizers should be between 6.5 and 8.5.
4. Moisture: The moisture content of organic fertilizer has a certain impact on its fertilizer efficiency and preservation. China stipulates that the moisture content of organic fertilizer should not exceed 40%.
5. Pathogens and harmful substances: the content of pathogens and harmful substances in organic fertilizers should be controlled within a certain range, so as not to cause harm to soil and crops. China stipulates that the total number of pathogens in organic fertilizers should not exceed 1000 / g, and the content of harmful substances such as heavy metals should meet the relevant national standards.
6. Maturity: The maturity of organic fertilizer refers to the degree of microbial decomposition of organic matter in organic fertilizer. In general, the higher the degree of maturation, the better the effectiveness of organic fertilizer. China stipulates that the maturity of organic fertilizer should not be less than 80%.
7. Granularity: The granularity of organic fertilizer has a certain impact on its application effect. China stipulates that the particle size of organic fertilizer should be between 1-50 mm.
This is the definition of organic fertilizer quality standards. In the actual production of organic fertilizer production lines, it is also necessary to adjust the formula and quality standards of organic fertilizer reasonably according to crop needs and soil conditions.
