What is liquid fertilizer? What is the method of use?

In recent years, with the continuous prominence of the advantages of liquid fertilizer and the strong advocacy of the country, more and more large growers choose to use liquid fertilizer, what is liquid fertilizer? What is the method of use? Let's take a look.

What is liquid fertilizer?

Liquid fertilizer is a kind of liquid fertilizer, which is sprayed directly on the leaves or roots of plants after mixing organic fertilizer or chemical fertilizer with water, so that it can be absorbed more quickly.

Liquid fertilizer can mobilize the physiological function of crops, give priority to development and mature early. it can effectively supplement the deficiency of various trace elements in crops and ensure the normal development of crops.

Liquid fertilizer contains a variety of plant activating elements, which can effectively inhibit soil consolidation caused by chemical fertilizer, improve pastoral geology, cultivate soil fertility, activate soil, promote underground root development, stimulate self-pollination and cross-pollination, increase seed setting rate, and preserve maturity and yield.

What is the method of using liquid fertilizer?

As plants are easily injured by direct contact with fertilizers, whether solid fertilizers or liquid fertilizers are mixed with water, the mixing ratio should be very careful not to be careless.

Liquid fertilizer is not an ordinary foliar fertilizer, it is only named after the existing form. At present, there are many foliar fertilizers in the market, which are not liquid fertilizers referred to in developed countries. Liquid fertilizer in agricultural developed countries has been popularized to about 40%, while China has just started. Liquid fertilizer is the liquefaction of solid fertilizer. In line with the national-guided development trend: that is super-enrichment, liquification, conducive to absorption, conducive to reducing transportation costs, such as American liquid fertilizer. Has opened the precedent of liquid fertilizer in China.

Matters needing attention in the use of organic liquid fertilizer

1. Pay attention to soil characteristics

The effect of fertilization is affected by the physical and chemical properties of the soil, when there are adverse limiting factors in the soil, it should be eliminated before the fertilizer efficiency can be improved; for example, when the soil is alkaline, the ammonium nitrogen fertilizer applied is easy to lose; the acid soil has a strong ability to fix phosphorus fertilizer, and the phosphorus applied is very easy to be fixed; another example is coarse soil, such as sandy soil, where fertilizer loss is greater.

2. Pay attention to the multiple of dilution

When the concentration of liquid solution is very high, direct application to crops will cause harm, and generally need to be diluted. Attention must be paid to the concentration of spraying leaves and the whole plant.

3. Pay attention to the maturity of organic materials

Liquid organic materials should not contain a large amount of decomposable carbon sources, otherwise the application will easily lead to the optimization of soil, resulting in a large number of microbial reproduction, resulting in crop growth disorders.

4. Pay attention to the balance of fertilization

Fertilizer application should pay attention to the balance of nutrients, should not be biased to excessive application of simple liquid fertilizer, especially too much nitrogen, have adverse effects on some crops, pay attention to the content of major nutrient elements, but also pay attention to the content of sub-components.
