At present, there are two types of solid and liquid foliar fertilizer on the market. Generally speaking, solid foliar fertilizer is better than liquid foliar fertilizer. Solid foliar fertilizer is divided into granular and powdery, and granular foliar fertilizer is better than powdery foliar fertilizer. Because the granular foliar fertilizer is processed by special technology, it has the advantages of easy application, high drying degree and easy preservation. Potassium formate is a foliar fertilizer with high potassium content, high solubility, easy absorption and safety.

Necessity of foliar fertilization with organic potassium formate:

1. Make up for the deficiency of root fertilization

When it is inconvenient to apply fertilizer at the root of crop emergence, such as in the late stage of crop growth, the vitality of root system declines and the ability to absorb fertilizer decreases; or when the soil environment is unfavorable to crop growth, such as excessive water, drought, over-acidity and over-alkali in soil, the root system of crop absorbs and runs against the wall, and the crop needs to resume its growth rapidly. When the method can not meet the needs of crops in time, only foliar spraying can quickly compensate for nutrients and meet the needs of crop growth and development.

2. Make up nutrition quickly

In the process of crop growth, crops have shown some deficiencies of nutrients, because it takes a certain amount of time for nutrient capacity to be absorbed by crops to adopt soil fertilization, which can not alleviate the symptoms of crop deficiency in time. At this time, the application of organic potassium formate foliar fertilizer on the leaves can make nutrients quickly enter the plant through the leaves and solve the problem of potassium deficiency.

3. Give full play to fertilizer efficiency

Some fertilizers, such as phosphorus, iron, manganese, copper and zinc fertilizers, are easily fixed by soil if they are applied as roots, thus affecting the application effect. However, foliar spraying will not be restricted by soil conditions. For example, some fruit trees and other deep-rooted crops absorb less potassium nutrients. If traditional fertilization methods are adopted, it is difficult to apply to the root absorption sites, and can not give full play to the fertilizer efficiency, while spraying potassium formate foliar fertilizer can achieve better results.

4. Economic Value

Trace elements are indispensable nutrients in the process of crop growth and development, but the amount of application is very small, such as molybdenum fertilizer, which is only tens of grams per mu. If root application method is used, it is not easy to apply evenly. Only foliar spraying can achieve economic and effective capacity. According to the research and calculation, potassium fertilizer is usually sprayed on the leaves of crops, and the utilization rate of potassium formate is more economical than that of root fertilizer in terms of economic benefits.

5. Reducing the pollution of soil

Nitrogen fertilizer can easily accumulate nitrate in groundwater and vegetables and cause damage to human health. If foliar fertilization with potassium formate is adopted, proper reduction of soil fertilization can reduce nitrate content in plants and residual mineral nitrogen in soil. Spraying potassium formate foliar fertilizer not only saves the amount of fertilization, but also reduces the pollution of soil and water resources.
