Corn plants turning purplish-red? Use potassium dihydrogen phosphate to help solve it

Can potassium dihydrogen phosphate be used as a top dressing? Of course it can.

As a highly efficient binary compound fertilizer, potassium dihydrogen phosphate can be applied both as a foliar fertilizer and through the roots, making it very easy for crops to absorb. That is why it is also a commonly used top dressing in agricultural production. Of course, potassium dihydrogen phosphate can likewise be used as a base fertilizer to supplement phosphorus and potassium for crops. However, the cost seems a bit on the high side, after all, there are other alternatives in production!

Potassium dihydrogen phosphate contains two of the three major elements, nitrogen, phosphorus and potassium. Phosphorus is a component of nucleic acids as well as various nucleoproteins, phospholipids, phytic acid and high-energy phosphate compounds, and plays an irreplaceable role in the growth and development of the plant organism. Potassium not only maintains osmotic pressure in cells, maintains cell balance and ion transport, but is also a catalyst for many enzymatic reactions in cells.

Both are indispensable throughout the entire growth cycle of plants, so naturally if deficiency symptoms appear during plant growth, top dressing is also very necessary. For example, if a plant lacks phosphorus, the plant shows a purplish color, while if it lacks potassium, the older leaves turn yellow. And the plant's growth rate is rather slow.

After dissolving in water, potassium dihydrogen phosphate hydrolyzes into phosphate ions and potassium ions, both of which are very easily absorbed. Therefore, when choosing a top dressing, foliar spraying can be considered. With spraying, the leaves absorb nutrients fairly quickly; generally speaking, they can be absorbed and utilized within one or two hours, which can very quickly relieve plants suffering from nutrient deficiency. If root application is chosen instead, although the fertilizer effect is rather slow, it can be released more persistently.

Potassium dihydrogen phosphate is in especially high demand during the reproductive growth stage of plants. For example, after spraying on watermelons, it can greatly improve the quality of the watermelons, not only having a sweetening effect, but also slowing down plant aging.
