Nutrients: Fertilizers usually contain the main nutrients needed by plants, such as nitrogen (N), phosphorus (P), potassium (K), and trace elements such as iron (Fe), zinc (Zn), manganese (Mn), etc. These nutrients are necessary for plant growth and development.
Nitrogen, Phosphorus and Potassium Ratio: The nitrogen, phosphorus and potassium (NPK) ratio of fertilizers is determined based on the needs of different plants and soil conditions. Different plants have different needs for nitrogen, phosphorus, and potassium at different growth stages, so the NPK ratio of fertilizers can be adjusted according to specific plant needs.
Controlled release method: Fertilizers can be divided into fast-release fertilizers and slow-release fertilizers according to the controlled-release method. Fast-release fertilizers provide the nutrients your plants need quickly, but for a shorter period of time, while slow-release fertilizers release nutrients gradually, providing a continuous supply of nutrients.
Fertilizer form: Fertilizer can exist in different forms, such as granular, powdery, liquid, etc. Different forms of fertilizer are suitable for different fertilization methods and soil conditions.
Organic Fertilizers and Inorganic Fertilizers: Fertilizers can be divided into organic fertilizers and inorganic fertilizers based on their sources. Organic fertilizers are made from organic matter (such as animal manure, plant residues, etc.) and can improve soil structure
