How Fertilizer Coating Materials Increase Fertilizer Efficiency

1. How Fertilizer Coating Materials Increase Fertilizer Efficiency In Agriculture Bio-link https://naqglobalsite.wordpress.com/2021/02/19/how-fertilizer- coating-materials-increase-fertilizer-efficiency-in-agriculture/ As the amount of productive land per capita reduces relative to the growing global population, the concern to improve agricultural productivity rises. Modern agriculture productivity has provoked challenges due to the increased demand of the population. Global food security is a significant concern as it can’t meet human needs. A significant culprit of lower food production is the low efficiency of conventional fertilizer absorbed by plants. To enhance crop productivity, slow-controlled release fertilizers are used that can increase nutrient use efficiency and lower the negative impact on the environment. Slow controlled-release fertilizers reduce nutrient loss, increase crop production, and reduce plant toxicity and stress. A wide range of fertilizer coating materials that is applied to granular or prilled nitrogen fertilizers. As urea includes higher amounts of Nitrogen of common soluble fertilizers, it has opted as a base material for most SCR. Wax, oils, Nitrogen, and synthetic polymers are used for coating and creating controlled release products.

2. Types of coated CRFs  Polymer  Sulfur  Sulphur plus polymer  Polymer-coated fertilizers They are types of CRF that are solid and coated with various polymers. They are used for controlling product longevity and nutrient efficiency. Polymer coatings can be semi-permeable or impermeable membranes having tiny pores in them. The major disadvantage of polymer-coated fertilizers is the coating material and process used for applying them. The nutrients released are not affected by soil conditions like PH, microbial activity, salinity, texture, or others but instead by temperature and moisture of the polymer coating. Polymer coated materials release through diffusion, osmotic pumping, and convective release by coating disruption. The release is mainly generated by distribution when water potential is steady, and the coating material is penetrated to the solutes inside. Benefits of PCF  Minimizes nutrient loss  Increase nutrient release timings  Reduce labor requirement

3.  Reducing plant toxicity  Reduce groundwater pollution  Uniform growth response. Sulfur Elemental sulfur was widely used for fertilizer coating. Molten sulfur is sprayed over urea granules, and sealant wax is applied to close any cracks or imperfections. Later it was adopted when sulfur was coated with a thin layer of organic polymer. Sulfur cuts down the solubility rate of fertilizer granules and slowly discharges nutrients into the soil. It is an essential nutrient that is beneficial for crops and usually used in alkaline soil to nullify the alkaline effect caused by its net acidic reaction. It is cheap and relatively eco-friendly to alkaline solids compared to other polymeric materials. The primary benefit of sulfur coated urea fertilizers is it enhances nutrients of Nitrogen and sulfur. Sulfur + polymer-coated To solve uneven nutrient release issues from sulfur-coated urea, a hybrid of sulfur and polymer-coated was developed. It includes thin polymer coating along with low-cost sulfur coating that provides a better seal than only sulfur and only polymer products. Polymer-coated urea has a water-insoluble layer that temporarily isolates the urea prill. The polymer coating could be resins or mineral-based products that act as semi-permeable membranes of impermeable membranes with tiny openings.

4. It is possible to predict and control the release rate of nutrients from this hybrid compared to other options. Dust control coatings As the name suggests, they are anti-dust agents that will reduce dust emissions. Fertilizer quality can be reduced from the production process through transport and storage; anti-dust agents prevent the fertilizers from stagnating and prevents dust contamination off from fertilizers. Coatings cannot enhance fertilizer that already faces quality problems; however, to minimize the common fertilizer quality issues, anti dust agents are used. The coating is an indispensable tool to produce high-quality granular fertilizer that meets the specifications. From performance and appearance to maintenance, the coating provides an array of benefits that can be achieved at a high level.
