Exploring Humic Acid: Structure and Classification Explained – Part 3
24. Humic Acid Organic Fertilizer
This fertilizer is mainly derived from humic minerals such as weathered coal, leonardite, peat, or clean organic biomass resources. It contains humic extract that, when applied to soil, improves soil fertility, provides plant nutrients, and enhances crop quality.
25. Humic Acid Organic–Inorganic Compound Fertilizer
An organic–inorganic compound fertilizer in which humic extract is the main source of organic matter. It contains a certain amount of water-soluble humic acid derived from humic minerals.
26. Humic Acid Blended Fertilizer (Humic Acid BB Fertilizer)
A granular fertilizer made by dry blending humic extract fertilizers and/or humic compound fertilizers, with at least two labeled nutrient contents.
27. Humic Acid Organic–Inorganic Blended Fertilizer (Humic Acid Organic–Inorganic BB Fertilizer)
A granular fertilizer produced by dry blending, where at least two of the nutrients, nitrogen, phosphorus, and potassium, are labeled, and a certain proportion of humic minerals or humic extract granules are added during the blending process.
28. Humic Acid Macronutrient Fertilizer
A fertilizer made by reacting or mixing humic extract with one or more macronutrient compounds of nitrogen, phosphorus, and potassium. It contains both humic minerals and specified levels of nutrient elements.
29. Humic Acid Medium-Element Fertilizer
A fertilizer produced by reacting humic extract with one or more medium-element compounds such as calcium, magnesium, or sulfur, containing humic acid and labeled nutrient elements derived from humic minerals.
30. Fulvic Acid Medium-Element Fertilizer
A fertilizer made by reacting fulvic acid with one or more medium-element compounds, such as calcium, magnesium, or sulfur, containing fulvic acid and nutrient elements.
31. Humic Acid Micronutrient Fertilizer
A fertilizer produced by reacting humic extract with one or more micronutrient compounds such as iron, manganese, boron, zinc, copper, or molybdenum, resulting in a product containing humic minerals and specified nutrient elements.
32. Fulvic Acid Micronutrient Fertilizer
A fertilizer made by reacting fulvic acid with one or more micronutrient compounds such as iron, manganese, boron, zinc, copper, or molybdenum, containing fulvic acid and nutrient elements.
33. Humic Acid Ultra-Micronutrient Fertilizer
A fertilizer produced by reacting humic extract with ultra-micronutrient compounds such as tin, lithium, iodine, or certain rare earth compounds. It contains both humic minerals and trace nutrient elements.
34. Humic Acid Beneficial-Element Fertilizer
A fertilizer created by reacting humic extract with beneficial element compounds such as silicon, sodium, cobalt, selenium, or aluminum. It contains humic minerals and specified beneficial elements.
35. Humic Acid Water-Soluble Fertilizer
A liquid or solid fertilizer containing water-soluble humic extract, designed for irrigation, foliar fertilization, soilless cultivation, seed soaking, and root dipping. It is derived from humic minerals and is suitable for efficient nutrient delivery.
36. Humic Acid Water-Soluble Silica-Potassium Fertilizer
An organic water-soluble fertilizer made from mineral-source potassium humate (a type of humic extract) combined with fully water-soluble potassium silicate. It contains humic minerals, potassium oxide, and silicon dioxide at specified levels.
