Organic fertilizers are mainly derived from plants and (or) animals, and are applied to the soil to provide carbon-containing materials with plant nutrition as their main function. It can provide comprehensive nutrition for crops, and has a long fertilizer effect. It can increase and renew soil organic matter, promote microbial reproduction, and improve the physical and chemical properties and biological activity of soil. It is the main nutrient for green food production.
Compound fertilizers refer to chemical fertilizers containing two or more nutrient elements. Compound fertilizers have the advantages of high nutrient content, few side-components and good physical properties. They are very important for balancing fertilization, improving fertilizer utilization, and promoting high and stable crop yields. The nutrient ratio is always fixed, while the types, quantities and ratios of nutrient elements required by different soils and crops are diverse. Therefore, it is best to test the soil before use to understand the texture and nutritional status of the field soil, and pay attention to the application of unit fertilizers in order to obtain better results.
