How to identify and apply water soluble fertilizer
Water-soluble fertilizer is a quick-acting fertilizer, which is widely promoted because of its good water solubility and no residue, and its high-quality properties that can be completely dissolved in water. What are the aspects of water-soluble fertilizer that need attention when applied? Tian Jialu, a soil and fertilizer expert at the Northwest A&F University, made a move for farmers to identify and apply water-soluble fertilizer.
"Water-soluble fertilizer refers to the nitrogen, phosphorus, potassium, calcium and magnesium trace elements that can be completely dissolved in water, and can be directly absorbed and utilized by crop roots and foliage. The rate of nutrient absorption by crops compared with traditional fertilizers. Faster, higher nutrient utilization. In general, water-soluble fertilizers will be effective within 10 days after fertilization, while traditional fertilizers will take effect after 20 to 30 days,†Tian Jiaxuan said.
Tian Jiaxuan said that the current water-soluble fertilizer products on the market are mixed, and the standards specified by the Ministry of Agriculture should be first understood. Most of the water soluble fertilizers implement the Ministry of Agriculture industry standard, namely the beginning of NY, the fertilizer registration certificate (Ministry of Agriculture). Be sure to apply water-soluble fertilizer from regular manufacturers to avoid using fertilizers that do not have heavy metal content on the fertilizer bag. The method for identifying water-soluble fertilizer is also relatively simple. The fertilizer can be dissolved in water. More than 95% of the qualified water-soluble fertilizer is soluble in water. The solution is clear and has no residue, or the sediment is few. On the contrary, the quality of the fertilizer is not good.
When applying water-soluble fertilizer, be careful not to spray on rainy or foggy days, otherwise the effect of water-soluble fertilizer will be greatly reduced. For fertilizers that have not been used up after opening, tighten the mouth and store in a cool, dry place at room temperature. The amount per acre, the concentration of water, and the number of applications should be increased or decreased according to the season and crop growth. Water-soluble fertilizer is a high-efficiency agricultural special fertilizer, and different varieties should be selected according to the crop and period.
