Can potassium dihydrogen phosphate be mixed with boron fertilizer and calcium fertilizer? Rational collocation of land for higher yield

On the question of how to apply fertilizer scientifically, I have talked about it many times before, but there are many kinds of chemical fertilizers, and each of them can not be introduced in detail. However, the principle of scientific fertilization and reasonable collocation of chemical fertilizer remains the same, for example, the acid-base is suitable, the efficiency of mixed fertilizer is not reduced, and mixing will not cause toxicity. If any of them cannot be satisfied, then they cannot be mixed and used together.

With regard to the combined application of potassium dihydrogen phosphate, boron fertilizer and calcium fertilizer, Scientific Xingnong said here: potassium dihydrogen phosphate and boron fertilizer can be mixed, but calcium fertilizer is not suitable. Let's introduce it in detail.

Potassium dihydrogen phosphate, as a high efficient fertilizer commonly used in agricultural production, can provide sufficient nutrients for plant growth, development and reproductive growth. It is also a very common fertilizer in topdressing or foliar fertilization. Boron fertilizer plays a key role in reproductive growth after flowering. Calcium fertilizer is absorbed through foliar or root after foliar spraying or soil root application, and participates in the composition of plant cell wall in plant cells. in the case of calcium deficiency, it should be cell division and root growth and development. at the same time, calcium is also very helpful for the absorption of potassium, nitrogen and phosphorus. As in grapes, it can also prevent fruit cracking and prolong the storage life of the fruit. It can be said that boron fertilizer and calcium fertilizer are also two necessary fertilizers for plants.

So whether the mixing of these fertilizers meets the above principles of chemical fertilizer mixing? Here we need to have an understanding of the properties of these fertilizers and chemical elements. first of all, let's look at potassium dihydrogen phosphate, which is weakly acidic and dissociates into potassium ions, hydrogen ions and phosphate ions after hydrolysis. As a mineral element, boron is usually combined with oxygen to form acid radical, such as borate, borate and phosphate are also negative ions, so there will not be any reaction between them. The combination of borate with hydrogen ion and potassium ion will not reduce the fertilizer efficiency, naturally, if these two kinds of fertilizers are mixed and used, it will also increase the yield.

The calcium ion is different, the metal divalent ion calcium combines with phosphate to form calcium phosphate, so it will form microprecipitation, at the same time, calcium ion and potassium ion will also have antagonistic reaction in the process of absorption, affecting each other's absorption and reducing fertilizer efficiency.

If you see it here, you must understand what is going on. In agricultural production, we must have a more correct understanding of the nature of fertilizers and the chemical properties of pesticides, otherwise it will not only increase production but also reduce fertilizer efficiency.
