NPK compound fertilizer: NPK compound fertilizer is composed of three nutrient elements: nitrogen (N), phosphorus (P) and potassium (K). They are essential nutrients for plants. Different crops have different requirements for these nutrients at different growth stages, so the ratio of NPK compound fertilizer can be adjusted according to the specific crop and growth stage.

Potassium magnesium phosphorus compound fertilizer: potassium magnesium phosphorus compound fertilizer is a special compound fertilizer, containing potassium, magnesium and phosphorus and other nutrients. Potassium is one of the important elements of plant growth and development, which can improve the disease resistance and stress resistance of crops. Magnesium is an essential element for chlorophyll synthesis and plays an important role in plant photosynthesis and growth. Phosphorus is a key element in plant growth, development and energy metabolism.

Organic compound fertilizer: Organic compound fertilizer is a fertilizer made from the mixture of organic matter and inorganic elements. Organic components can improve soil structure, provide nutrients needed by plants, and promote microbial activity in the soil. Organic compound fertilizers often contain a variety of ingredients such as organic fertilizers, mineral fertilizers and microbial fertilizers, which provide comprehensive nutrition and biological activity.
