How to use Potassium Fertilizer?

Feb. 26, 2020

As a Potassium Fertilizer Supplier, share with you.

Potassium Fertilizer is one of the important fertilizers necessary for crops. Potassium fertilizer can promote crop nutrient transport, fruit enlargement, tissue maturity, accelerate growth and increase resistance. What are the differences between common potassium fertilizers? How do I apply it? What should I pay attention to when applying potassium fertilizer?

What is the difference between common potassium fertilizers?

Potassium sulfate White or light yellow crystal, soluble in water, low hygroscopicity. It can be used as base fertilizer and topdressing fertilizer. It is suitable for all kinds of crops, especially the crops that avoid potassium chloride.

Potassium nitrate White powder or crystal, soluble in water, low hygroscopicity. Because it has other functions, it is generally difficult to buy on the market.

Potassium dihydrogen phosphate colorless to white crystal or crystalline powder, soluble in water and stable in air. At present, it is mostly used for seed soaking and extra-root dressing.

Biological potassium fertilizer can be used for seed dressing, dipping roots, or applied to the soil. The application of the fungicide is actually inoculating the roots of the crops, allowing the silicate bacteria to release potassium, phosphorus, silicon, iron and other elements in the soil around the roots for absorption and utilization by the roots.

What should you pay attention to when applying potassium fertilizer?

The application of potassium fertilizer from soil to soil should first be put in areas where the soil is seriously deficient in potassium. From the perspective of soil texture, the available potassium content of sandy soil is often low, and potassium fertilizer should be added; the available potassium content of clayey soil is often high, and it can be applied less or not. Potassium sulfate can be applied to soils lacking potassium and sulfur, and potassium chloride cannot be applied to saline-alkali soils.

Because the crop application is used in rainy areas or areas with irrigation conditions and good drainage conditions, most crops can be applied with potassium chloride, and a few cash crops are not suitable for improving quality.

It is better to choose potassium sulfate for tobacco, sugar crops and fruit trees. Due to the high cost of potassium sulfate, potassium sulfate can be used for high-efficiency economic crops. Generally, field crops should use cheaper chlorine except for a few chlorine-sensitive crops. Potassium.

How to apply potassium fertilizer?

Foliar spraying is best when potassium-requiring crops are in rapid growth. When the crop root system is developed, it is best to apply it in deep layers. Common conservation tillage leaves more crop residues on the soil surface, which also causes higher concentrations of potassium to accumulate on the soil surface and not to penetrate deep into the soil. When soil moisture is good, these potassium can smoothly infiltrate, but when the soil is dry, it will limit the absorption of potassium. This misalignment can lead to a potassium deficiency in the crop, as the crop takes root deeper below the most potassium-rich soil layer in order to obtain sufficient water. In this case, deep application of potassium fertilizer can significantly increase potassium availability.
