The Difference Between Blended Fertilizer, Controlled Release Fertilizer and Compound Fertilizer

Blended fertilizer, controlled release fertilizer, compound fertilizer difference - blended fertilizer is also known as BB fertilizer, dry blended fertilizer, is in nitrogen, phosphorus, potassium three nutrient elements in any two or three types of fertilizer, is a modular fertilizer or compound fertilizer as raw materials, according to the simple mechanical equipment mixed and made, no significant chemical changes in the mixing link. Many people are not sure what the difference between blended fertilizer, controlled release fertilizer, compound fertilizer is? Today we will do the actual detailed introduction!

Blended fertilizer is all two or three types of fertilizers containing nitrogen, phosphorus and potassium nutrient elements to modular fertilizer or in line with the fertilizer as raw materials, according to simple mechanical equipment mixed and made very simple, itself can also be based on different food crops and soil layer to make the appropriate fertilizer.

Blended fertilizers [are two or more types of granular, highly nutritious raw materials. It is especially suitable for areas with large land area, complicated soil texture and a wide variety of crops. It is made of modular fertilizer or compound fertilizer as raw material and mixed according to simple mechanical equipment without significant chemical changes in the mixing process. There are two kinds of compound fertilizer processing process, one is physical mixing method of production and manufacturing down called compound fertilizer, the other is with nitrogen, phosphorus and potassium elements of minerals through chemical changes established called compound fertilizer.

Controlled release fertilizer is based on the outer film encapsulation and coupled with the slow polymerization agent and other methods to make the dissolution of fertilizer, release out when the increase is beneficial to enhance the use of fertilizer nutrients, and thus to increase the effective period of fertilizer to promote the agricultural industry to increase yields and incomes is one of the key marketing promotion fertilizer Ministry of Agriculture. Universal controlled release fertilizer is probably divided into: fertilizer package fertilizer, epoxy resin film coating and urease inhibitor, etc., according to the differences in processing can be divided into: combined mixed and compound fertilizer type, etc.

Compound fertilizer nutrient content is high, less by-products and good physical characteristics, to promote crop yield and high yield has a key effect, its concentration value is relatively large differences should pay special attention to the selection of appropriate concentration value, to prevent direct contact with seeds and fertilizers, otherwise it will endanger the germination and even burn seedlings and rotten roots; compound fertilizer preparation raw materials are different should pay attention to the scope of application of nutrient components. Different well-known brands, different concentration values of compound fertilizer applied raw materials are different, in the production and manufacture of soil texture and crop type selection application, otherwise it will reduce fertility and even harm crops. Use to try to prevent the surface chasing should be ditching and filling the soil.
