Whether we are planting any crops, we will use foliar fertilizers, especially potassium dihydrogen phosphate. Potassium dihydrogen phosphate has a great effect on the growth of crops, so many farmers use it. However, there are many fakes in the market. In order to avoid buying fakes, many people will make potassium dihydrogen phosphate. How do you do this? Let's take a look at the following.
Potassium dihydrogen phosphate
Potassium dihydrogen phosphate is a high concentration of high quality non-chlorine, phosphorus and potassium fertilizers with very low salt values, high nutrient content and suitable for use on a variety of crops. It can not only promote fruit expansion, color change, but also promote crop metabolism, but also improve crop rooting, antifreeze and stress resistance. Now the use of potassium dihydrogen phosphate has become very common. It is basically a physiologically neutral fertilizer. The water solubility is very good, mainly because its phosphorus (P2O5) accounts for 52% and potassium (K2O) accounts for 34%. And there is more than 80% utilization, so it is the first choice for foliar potash.
Many farmers' friends have been using potassium dihydrogen phosphate, but they are worried about buying fakes in the market. How to deal with this situation? The following small series will share how to make potassium dihydrogen phosphate, and basically do not use How to spend money.
Method for making potassium dihydrogen phosphate
What is the method? You can use 30 kg of water plus 6 kg of ash, plus 2 kg of potassium phosphate, then mix and let it settle for a few hours, so that the potassium dihydrogen phosphate solution is ready. Of course, this method is mainly aimed at some farmers who are still using the fire to cook in the countryside, because he will have a lot of grass ash to use, if not, then it is best, I suggest you buy some big factories in the market. Potassium dihydrogen phosphate, the big manufacturers came out basically no big problem.
How to use homemade potassium dihydrogen phosphate
How do we use potassium dihydrogen phosphate ourselves? After we have prepared it, add 100 kg of water, let it settle, and then pour it directly into the sprayer without diluting it. It can be sprayed directly. More than 30 kg of solution plus 100 kg of water can be used directly. This method is very practical and does not cost money.
Precautions for the use of potassium dihydrogen phosphate
1 When using potassium dihydrogen phosphate at a high concentration, it is necessary to avoid high temperature. Generally, high concentration is not recommended for high temperature seasons.
2 Potassium dihydrogen phosphate should be used before 10:00 am and after 4 pm.
3 potassium dihydrogen phosphate can be mixed with acidic and neutral pesticides to increase the efficacy and can not be mixed with alkaline substances.
4 Potassium dihydrogen phosphate is a water-soluble fertilizer that dissolves in water, please store it in a cool dry place. Seal the bag when it is not used.
5 potassium dihydrogen phosphate should be purchased from a regular manufacturer, because the high-purity potassium dihydrogen phosphate foliar spray is very high in utilization and absorbs quickly. However, if the low-purity or fake foliar fertilizer can not only increase crop yield, it may also cause serious losses.
The above is about the method of self-made potassium dihydrogen phosphate and the precautions for its use. As a common foliar fertilizer, we must have a deep understanding of its effects and matters, so as to ensure that the use is in place and the crops are highly productive. .
