Water-soluble fertilizer

Water-soluble fertilizers (also known as water-soluble fertilizers) refer to water-soluble fertilizers containing macronutrients in elemental form, compound water-soluble fertilizers, water-soluble fertilizers specified by the Ministry of Agriculture and Rural Affairs, and organic water-soluble fertilizers that dissolve rapidly in water.
Compared to conventional granular compound fertilizers, water-soluble fertilizers offer advantages such as comprehensive nutrient content, high nutrient concentration, and low levels of water-insoluble substances. They dissolve quickly in water and are readily absorbed and utilized by crops. Water-soluble fertilizers vary in type based on different classification criteria. By physical form, they are categorized into solid water-soluble fertilizers and liquid water-soluble fertilizers. Solid water-soluble fertilizers can be further divided into granular and powdered forms based on their specific solid state, while liquid water-soluble fertilizers are classified as clear liquid-type or suspension-type based on their liquid state.
Based on function, water-soluble fertilizers can be categorized into nutritional and functional types. Nutritional fertilizers primarily supplement nutrients essential for crop growth, including macronutrient, mesonutrient, and micronutrient formulations. Functional water-soluble fertilizers incorporate active substances derived from plant, animal, or mineral sources, such as organic water-soluble fertilizers containing humic acids, amino acids, or alginic acids. These enhance soil quality, stimulate crop growth, and improve crop quality.
