Speaking of potassium dihydrogen phosphate compared to farmer friends are quite well understood, as a foliar fertilizer with the highest phosphorus and potassium content now, potassium dihydrogen phosphate has been highly sought after by farmers and friends, not only because the benton fruit of potassium dihydrogen phosphate sweetening and color conversion effect is good, but also because potassium dihydrogen phosphate is suitable for any kind of crop application, whether it is fruit trees, fields, cash crops or Chinese herbal medicines can be applied, but although potassium dihydrogen phosphate yield increase and quality is good for a wide range of applications, However, if you mix with these pesticides or fertilizers when you apply them, there will be problems, and today we will talk about the best fertilization method of potassium dihydrogen phosphate.
Foliar spray of potassium dihydrogen phosphate on vegetable fields
First, potassium dihydrogen phosphate can not be mixed with alkaline agents or fertilizers
Potassium dihydrogen phosphate is acidic after water-soluble acid-base pH, so if potassium dihydrogen phosphate is applied together with alkaline pesticides or fertilizers, such as our common Bordeaux liquid, copper hydroxide, etc., then a chemical reaction will occur, flocculation precipitation will occur in the aqueous solution, and the effect of potassium dihydrogen phosphate and mixed alkaline products will be greatly reduced, causing economic losses, and serious impacts on crops.
Second, can not be mixed with calcium fertilizer
The content of phosphorus in the genuine potassium dihydrogen phosphate ≥52%, how to mix with calcium fertilizer, at this time the phosphorus ion of potassium dihydrogen phosphate will antagonize with calcium ions to form a large molecule of calcium superphosphate, calcium superphosphate is not absorbed and utilized by crops, even if it is not applied at the same time, the potassium dihydrogen phosphate and calcium fertilizer are applied separately, as long as the interval period does not exceed at least one week, it will affect the absorption of calcium elements, and it is not conducive to the growth of crops.
Third, mixed with carbonate pesticides or fertilizers
Farmers in the topdressing potassium dihydrogen phosphate, how to apply together with pesticides or fertilizers containing carbonate, carbonate will have a chemical reaction with the hydrogen ions in potassium dihydrogen phosphate, the formation of carbon dioxide caused by fertilizer volatilization, common carbonate products in the agricultural planting process are sodium bicarbonate, potassium carbonate and so on.
Farmers spray wheat with potassium dihydrogen phosphate
Potassium dihydrogen phosphate is used in any crop, generally in the crop topdressing is more common is through foliar spray topdressing, crops in the use of potassium dihydrogen phosphate topdressing want to achieve the best fertilization effect, there are two aspects of farmers must pay attention to.
First, the time of fertilization; potassium dihydrogen phosphate, as the binary compound fertilizer with the highest phosphorus and potassium content on the market so far, the best fertilization time is the best at the peak of the demand for phosphorus and potassium in crops, such as crop flowering buds, swelling fruit sweetening and color change, etc., which can effectively improve the flowering and fruit setting rate, accelerate fruit expansion, increase fruit nutrient content, and achieve the purpose of increasing yield and quality.

The second is to match fertilization; potassium dihydrogen phosphate will reduce the negative impact of fertilizer efficiency when mixed with some pesticides or fertilizers, but at the same time it can also play a 1+1>2 effect with some pesticides or fertilizers, such as potassium dihydrogen phosphate and urea in a reasonable proportion of mixing is a good compound fertilizer, potassium dihydrogen phosphate and permethrin pesticide mixing, can enhance the efficacy, potassium dihydrogen phosphate and boron fertilizer mixing, can promote boron absorption, promote crop reproductive growth, prevent corn bald tip to achieve high yield effect is very obvious.

The above is about the agricultural planting process of the application of potassium dihydrogen phosphate related content, any kind of fertilizer has a good side and a bad side, for farmers engaged in agriculture, what we have to do is through learning, make full use of the good side of fertilizer to achieve a high yield harvest.
