Functions & Benefits
- - - -
| # Enhancing nutrient uptake by combining nutrients and humic aid as well as keep a well-balanced nutrition. # Improving the structure of soil, increasing the buffering powder of soil, optimize N. P. K absorption by plants. # Neutralizing both acid and alkaline soils, regulating the PH value of soils, with the prominent effect in alkaline and acidic soil # Reducing nitrate leaking into the groundwater and protect the underground water # Enhancing the resilience of crops, such as cold, drought, pest, disease and toppling resistance # Stabilizing nitrogen and improving nitrogen efficiency (as an additive with urea) # Promoting healthier, stronger plants and beautifying appearance # Petroleum drilling fluid decreasing and filtering agent # Boiler anti-scaling agent and water quality stabilizer # Cementing agent for pulverized coal shaping # Removing toxic metals and their ions from wastewater # Dispersing agent and deflocculating agent # Assisting in the removal of trace amounts of grease, oil, liquid organics and suspended matter |
