Introduction of Blending fertilizers:
Blending fertilizers, also called Blended fertilizers, are obtained by mechanically mixing several single fertilizers, or a single fertilizer and binary or ternary compound fertilizers. Sometimes fillers can be added to improve the physical and chemical properties of the fertilizer. For example, in order to prevent excessive acidification of ammonium nitrate and general fertilizers made of calcium phosphate, some lime can be added to neutralize the excessive acidity of the soil to create more favorable conditions for crop growth. Some single fertilizers should not be mixed with each other, such as mixing ammonium sulfate and plant ash, which will cause nitrogen loss.
What equipment is needed for blending fertilizers?
Blending fertilizers need to use the Blending fertilizers production line. The Blending fertilizers production line is composed of a computer-controlled static batching system → lifting silo → mixing mixer → Fertilizer packing machine → belt conveying and stacking.
Blending fertilizers production line application:
The equipment of the blending fertilizers production line integrates batching, mixing and packaging, and is especially suitable for the batching and mixing of BB fertilizers. The blending fertilizers production line has a small area; the capital investment in plant and equipment is small, and it is especially suitable for small fertilizer factories and fertilizer distributors.
Why use Blending Fertilizers?
Vegetables need a variety of nutrient elements for growth and development. Usually, most of the chemical fertilizers we buy in production only contain one element or two elements. For example, urea, ammonia, ammonium bicarbonate, etc. are very simple nitrogen fertilizers, and potassium chloride is also very simple. Potash fertilizer, only a few compound fertilizers contain multiple nutrients. In production, two or more fertilizers are often mixed and applied later, which can reduce the number of fertilizer applications.
Prospects for Blending Fertilizers:
The production of blending fertilizers can use physical and chemical fertilization technology to improve fertilizer efficiency, reduce fertilization times, and save fertilization costs. The production and application of Blending Fertilizers have attracted widespread attention from all over the world. Blending fertilizers are a response to the development of the world’s chemical fertilizer industry. The world’s consumption has exceeded 1/3 of the total consumption of chemical fertilizers. Due to the diversification of crops, the soil has also changed from the so-called “corrected fertilization” that overcomes the lack of single nutrient elements in the past. A “balanced fertilization” with a combination of nutrients. For this reason, it is imperative to accelerate the development of the Blending Fertilizers industry.
How to blend fertilizers?
1. It can be mixed: ammonium sulfate and superphosphate, ammonium sulfate and phosphate rock powder, urea and phosphate fertilizer, ammonium nitrate, and potassium chloride. After they are mixed, they form a compound fertilizer of nitrogen, phosphorus and nitrogen, and potassium, which not only has no loss of nutrients but also reduces the adverse effects of various fertilizers when applied separately and improves fertilizer efficiency. For example, when ammonium nitrate and potassium chloride are mixed, the deliquescence is small and good The physical properties of it are easy to apply. The mixed application of ammonium sulfate and phosphate rock powder can increase the solubility of the phosphate rock powder and improve the fertilizer efficiency of the phosphate rock powder.
2. Conditions that can be mixed temporarily but not for a long time: some fertilizers should be applied immediately after mixing, and will not cause adverse effects on vegetable crops, but if they are mixed for a long time, it will cause the effective nutrient content to decrease and the physical properties to deteriorate. For example, the mixture of superphosphate and nitrate nitrogen fertilizer (ammonium nitrate, etc.) is more prone to deliquescence, and can also cause the gradual decomposition of nitrate nitrogen, resulting in nitrogen loss. After urea is mixed with potassium chloride, lime nitrogen, and potassium chloride and placed for a long time, it will increase the hygroscopicity and deteriorate the physical properties of the fertilizer.
3. Non-mixing conditions: After mixing this type of fertilizer, it will cause nutrient loss and reduce fertilizer efficiency. For example, ammonium nitrogen fertilizers (ammonium nitrate, ammonium sulfate, etc.) mixed with alkaline fertilizers (such as lime, steel slag phosphate fertilizer, lime nitrogen or plant ash, etc.) will cause nitrogen loss. For example, if quick-acting phosphorus fertilizers such as superphosphate are mixed with alkaline fertilizers such as lime nitrogen, lime, steel slag phosphate fertilizer, plant ash, etc., it will cause phosphoric acid degradation and reduce the effective phosphorus content. The mixing of poorly soluble phosphate fertilizers with alkaline fertilizers makes it more difficult for crops to absorb and utilize the phosphorus in poorly soluble phosphate fertilizers.
