The effect of potassium dihydrogen phosphate fertilizer is good, but it is rarely used as a base fertilizer. You can know why.

Potassium dihydrogen phosphate can be used as base fertilizer, but it is not recommended! If it is for family gardening to grow a little flowers and plants, it is understandable to choose potassium dihydrogen phosphate as the base fertilizer, but if the farmer chooses the base fertilizer, I believe that no farmer will choose potassium dihydrogen phosphate as the base fertilizer, because potassium dihydrogen phosphate is too expensive.

The benefit of farmers is calculated on the basis of input and output. If large inputs cannot be exchanged for efficient output, I believe no one will choose so. Friends with agricultural production experience should know that potassium dihydrogen phosphate is much more expensive than phosphate fertilizer and potassium fertilizer separately, and potassium dihydrogen phosphate only contains two elements of phosphorus and potassium. There are many options for crops to supplement phosphorus and potassium: for example, calcium superphosphate, potassium chloride, or potassium sulfate are good choices.

In terms of fertilizer efficiency, although it saves a lot of effort to use potassium dihydrogen phosphate alone, the current agricultural production is basically mechanized fertilization, in fact, the separate use of chemical fertilizer does not increase much hard work. Here, scientific performance suggests that separate use of phosphate and potassium fertilizer can be considered. Although potassium dihydrogen phosphate can be used as a base fertilizer, it is really not worthwhile.

In addition, we need to remind everyone that there are lawbreakers who fake potassium dihydrogen phosphate with potassium sulfate or even the cheapest "magnesium sulfate", so that farmers are often unable to tell the true from the fake when they buy. Potassium sulfate and sodium sulfate are white in appearance, while potassium dihydrogen phosphate crystals are transparent, so they can be easily identified from the appearance.

Here is science to promote agriculture, the above is the original content, welcome to add attention, take you to grow knowledge.
