Strong root Water soluble fertilizer containing humic acid Nitrogen ≥ 50g/L phosphorus≥ 150g/L potassium≥ 20g/L Mineral-derived humic acid≥ 120g/L Mineral-derived fulvic acid≥60g/L1. Release solidified phosphorus, prevent phosphorus curing, with good compatibility and mixability. 2. Effectively resist the harm of high salt value to the soil, long-term use can effectively reduce sodium ions and chloride ions in the soil, thereby effectively reducing the soil salinity value. 3. The effect of activating trace elements can promote the absorption and utilization of trace elements, improve the soil structure, and make the soil looser with long-term use. 4. Rich in natural biostimulants, it can promote the synthesis of various enzymes of crops themselves, stimulate root growth, improve nutrient absorption rate and photosynthetic efficiency, enhance crop stress resistance, and activate plant growth potential.
