Comparison of the advantages and disadvantages of mineral potassium humate and biochemical potassium humate
Advantages
Mineral source humic acid
1. The raw material is pure natural minerals
2. The main component is functional groups, good stability and activity
3. Strong ion adsorption, replacement, complexation and chelation capabilities
4. There is a natural redox system
Biochemical potassium humate
1. The raw material source is wide and easy to obtain
2. The reuse of waste resources is conducive to resource conservation and environmental protection
3. Small molecules, fast fertilizer effect and good solubility
4. Relatively cheap
5. Safe, no taste, no pests and diseases
6. High humus content, suitable for long-term application
7. High cost performance, suitable for long-term application
Disadvantages
Mineral source Humic acid
1. The source of raw materials is limited and it is a non-renewable resource
2. The nutrients are released slowly and the effect is slow
3. The solubility is relatively poor (generally, the solubility of black humic acid is poor, and the solubility of yellow humic acid is relatively good)
4. The price is relatively high
Biochemical potassium fulvic acid
1. It is not suitable for long-term application, and it will cause bacteria and pests
2. The main components are sugar and protein, which are metabolized quickly and the fertilizer effect lasts for a short time, and it cannot improve the soil for a long time
3. The application amount per acre is large, and the price is relatively high
4. It is easy to absorb moisture and is not suitable for storage
5. Humic acid has low purity and is not completely decomposed. It is very easy to produce gas after entering the soil
6. Poor stability, the carbon chain is easy to break, and excessive application will cause soil compaction
