How to select compound fertilizer for your plants?

After further granulation by drum granulator, the compound fertilizer contains nutrients required by a variety of plants, which is better than a single chemical fertilizer. So how to choose compound fertilizer?

1. Look at the packaging. Qualified products are packed in double layers to prevent moisture. There are three license numbers on the packaging surface: production license number, business license number, product quality registration certificate number, nitrogen, phosphorus and potassium content identification, and manufacturer and address. Open the outer package and there should be instructions in the bag.

2. Look at the physical properties of compound fertilizer. Compound fertilizer with good quality, uniform particle size, no caking and no pulverization.

3. Buy compound fertilizer produced by regular manufacturers. The fertilizer production line and production technology of regular manufacturers are relatively advanced, the product quality is reliable and the reputation is guaranteed.

4. Select the compound fertilizer suitable for the local area. The locally produced compound fertilizer is mostly produced according to the soil nutrient content, crop fertilizer demand law and fertilization effect in this area and surrounding areas, which is highly targeted.

5. Avoid using “dichloro” compound fertilizer for many years. “Dichloro” compound fertilizer is a compound fertilizer produced with ammonium chloride and potassium chloride as raw materials. If the “dichloro” compound fertilizer is applied year after year, the amount of chloride ions stored in the soil is large, and excessive absorption by crops will cause “chlorine damage” and soil will also cause “salt damage”.

Whether planting flowers or vegetables, we should follow the fertilization principle of “giving priority to organic fertilizer and supplemented by chemical fertilizer”. The long-term single large-scale use of chemical fertilizer is easy to cause soil hardening, soil fertility decline and soil acidification.

On the contrary, it will limit crop yield and affect product quality. Therefore, after purchasing NPK compound fertilizer granulator, we must pay attention to the treatment of various nutrient compound fertilizers.

Why so many people use organic fertilizer for their plants?

The advantages of organic fertilizer processed by organic fertilizer manufacturing equipment are as follows:

(1) Organic fertilizer is a kind of agricultural fertilizer processed by the equipment system of organic fertilizer production line. Organic fertilizer not only contains a large number of nutrients and trace elements necessary for plants, but also contains rich organic nutrients such as humic acid, Vitamins, auxin, antibiotics and small molecule compounds of organic nitrogen and phosphorus.

Therefore, organic fertilizer is the most comprehensive fertilizer. In addition, the amount of organic fertilizer allowed varies widely and usually does not harm crop growth. The use of organic fertilizer not only increases the crop yield in the current season, but also remains effective after several years, and the effect of fertilizer is slow and lasting.

(2) Organic fertilizer can improve soil physical and chemical properties and soil fertility. Organic fertilizer contains a lot of organic matter, generally about 200g / kg. Organic matter is an important material basis of soil fertility. Humus is the main part of soil organic matter, accounting for 50% – 65% of the total soil organic matter.

Humus is a complex organic colloid, which can adjust and buffer soil pH. Increasing the amount of soil cation substitution can improve the soil fertility retention; Increasing the content of soil organic matter is conducive to the formation of good soil structure, especially water stable aggregates. Increasing soil structure can improve soil compactness, aeration, water holding rate and thermal conditions, which have a good effect on water and determine soil fertility by fertilizer, gas and thermal conditions.

It is beneficial to improve the physical and chemical properties of soil and improve soil fertility.

(3) Organic fertilizer promoted soil microbial activity. Soil microorganism plays an important role in the transformation of organic matter, and is one of the important indicators to measure the level of soil fertility.

For example, the mineralization process of organic matter in soil, the effective process of organic nitrogen and phosphorus in soil and the biological nitrogen fixation process of beans are all related to the role of soil microorganisms.

Therefore, on the one hand, the application of organic fertilizer increased the number and quantity of beneficial microorganisms in soil, on the other hand, it provided good environmental conditions for soil microbial activity, and significantly enhanced soil microbial activity.
