Can potassium dihydrogen phosphate be used as topdressing? Yes, of course.

As a highly efficient binary compound fertilizer, potassium dihydrogen phosphate can be used as both foliar fertilizer and root fertilizer, which is very beneficial to crop absorption. Therefore, it is also a commonly used topdressing in agricultural production. Of course, potassium dihydrogen phosphate can also be used as a base fertilizer to supplement phosphorus and potassium for crops. However, the cost appears to be a little higher, after all, there are other options in production!

Potassium dihydrogen phosphate contains two major elements of nitrogen, phosphorus and potassium. Phosphorus, as a nucleic acid and a variety of nuclear proteins, phospholipids, phytins and high-energy phosphate compounds, all contain phosphorus, which plays an irreplaceable role in the growth and development of plants. Potassium not only maintains osmotic pressure, cell balance and ion transport, but also acts as a catalyst for many enzymatic reactions in cells.

Both of them are indispensable in the whole plant growth cycle. Naturally, if there are symptoms of element deficiency in the process of plant growth, topdressing is also very necessary. For example, if the plant is deficient in phosphorus, the plant appears purple, while if it is deficient in potassium, the old leaf is yellow. And the plant growth rate is slow.

Potassium dihydrogen phosphate is hydrolyzed into phosphate ion and potassium ion after dissolving in water, both of which are easily absorbed. Therefore, foliar spraying can be considered in the selection of topdressing. In the case of spraying, the leaves can also absorb nutrients quickly, generally speaking, they can be absorbed and used in one or two hours, which can be relieved very quickly for the plants with deficiency of nutrients. If you choose root application, although the fertilizer effect is slow, but the fertilizer effect can be more lasting release.

Potassium dihydrogen phosphate is generally in great demand during the plant reproductive growth period. For example, after spraying watermelon, it can greatly improve the quality of watermelon, not only play a sweetening effect, but also slow down plant senescence.
