HOW TO PRODUCE CONTROLLED - RELEASE NITROGEN FERTILIZER

Encapsulation of fertilizers in polymeric coatings is a method used to reduce fertilizer losses and to minimize environmental pollution. Polysulfone was used for a coating preparation for soluble NPK granular fertilizer in controlled-release fertilizer formulations. The coatings were formed by the phase inversion technique (wet method). The influence of the polymer concentration in the film-forming solution on the physical properties of the coatings was examined. The coating structure controls the diffusion of the elements from the interior of the fertilizer granule. It was experimentally confirmed that the use of polysulfone as a coating for a soluble fertilizer decreases the release rate of components.

Moreover, the release rate of nutrients from coated granules decreases with the decrease of the coating porosity. In the case of coating with 38.5% porosity, prepared from 13.5% polymer solution after 5 h of test, 100% of NH(4)(+) was released, whereas only 19.0% of NH(4)(+) was released after 5 h for the coating with 11% porosity. In addition, coating of fertilizers leads to improvement of handling properties, and the crushing strength of all coated fertilizers was an average 40% higher than that for uncoated NPK fertilizer.

FERTILIZERS AND PRODUCTIONS

LIQUID OR SOLID FERTILIZER PRODUCTION is not very complicated. For the production, there is need usable and tried a formulation, raw materials and mixing tank. For raw materials to be used, quantities to be used and ingredients usage rankings, you should look into this formulation. Therefore, formulation and productıon methods of FERTILIZERS are important. If you have not a good formulation, you cannot make healthy and efficient production of any fertilizer.

If you need any manufacturing formulations and production methods about

This encyclopedia has many formulas about NPK fertilizers,NP fertilizers,liquid poliar fertilizers, powder fertilizers, granulas fertilizers, calcium and potasium fertilizers, special fertilizers, dripping fertilizers,foliar fertilizers, edta chelated fertilizers, micronutrients fertilizers,macronutrients fertilizers,chelated fertilizers etc.

All chemical fertilizers in the encyclopedia are producible easily.You need no help and no technıcal support. The encyclopedia is enough to produce chemical fertilizers itself.
