The exponential growth of the global population has urged the agriculture sector to increase crops' production and augment the food supply, consequently impacting food production costs.

Simultaneously, inefficient uses of fertilizer products have also affected myriad environmental issues with devastating effects on groundwater

and

Along with new growing crop nutrition methodologies, these factors push the speciality fertilizer market to produce more

innovative and efficient products with minimal environmental

damage. The coating is an approach that can make speciality

products and enhance the quality of the existing product. There are various coating materials applied to fertilizer particles to control solubility in soil. Usually, the materials are used for granular or prilled nitrogen fertilizer.

Fertilizer coating materials include the highest N or prilled

Nitrogen, the base material for most coated fertilizers. Elemental

sulphur was used for fertilizer coating previously, spraying molten sulphur over the urea granules. Beyond these, other coated fertilizers materials are formulated by reacting various resin-based polymers on the surface of fertilizer granules.

Anti dusting agents are used to produce dust-free fertilizers that will provide consistent and predictable application results.

Know About: Defoamer Chemical How to choose the right Deformer, and which is the proper method to test?

There are an array of considerations in the choice of defoamer. It

depends upon the type of product, requirement of industries, shell life, methods and much more.

There are two types of laboratory methods used that are relevant to release time. The standard practice incubates common release

fertilizer for specific nutrient release time until a threshold amount

of nutrients is released. The other is an accelerated method that sets CRF for a shorter time at a particular higher temperature.

 The temperature-controlled incubation method or the standard procedure-

TCIM method involves incubating a beaker that contains CRF and water at a consistent temperature of 77 degrees F.  Accelerated incubation method The accelerated method uses four samples placed in hollow glass tubes wrapped by a water jacket where pieces are placed in the

water, and water controls the temperature. The temperature is

increased from about 77 to 140 degree F over time to release the curve. Ether water of dilute citric acid is used as the extracting solution.

Another method is observed using five separate funnels to incubate resin-coated CRF at a temperature of 122 to 194 degree F and divulged that 176 was the right temperature partially due to reduced coating integrity of 194 degree F.

The accelerated lab test method's primary benefit is it reduces time

and cost compared to standard approaches. These are lab tested methods for achieving the best testing results.

suppliers use high agitated paint inserted into a density cup and then measure paint density. The colour is sealed and stored and later measure after a certain period to notice the density changes.

 Spray coating method: Anti dust Agent Suppliers use

defoamer for paint that is stirred at higher speed and poured immediately on polyester film in which the frame is placed at an angle of 25 degrees. The surface state of the dry film is observed.

There are many extensive testing methods to know the efficiency of

anti dust agents, cycling bubble methods, gas drum methods, etc.
