A Sulfur Coated Urea Was Prepared By Coating The Granules With Molten Sulfur After They Were Preheated

 

Sulfur Coated Urea

Sulfur coated urea is primarily used in agriculture to mitigate the negative effects of fertilisers like crop burn. They are essentially a controlled release of fertilisers made by coating hot urea with molten sulphur polyurethane oil. These are specialised fertilisers that are coated with polymers or waxes to allow nutrients to be released slowly. They're common in professional lawn care and turf, greenhouses, horticulture, golf courses, and nurseries. Growing concern about eutrophication caused by increased fertiliser use, which results in water pollution. Sulfur coated urea is effective in reducing fertilizer's negative effects on aquatic life.

Due to rising environmental concerns, farmers are expected to adopt more advanced and sustainable farming practises, which is expected to boost the market growth of sulphur coated urea over the forecast timeframe. Due to the scarcity of arable land, there is an increased demand for high-yielding agricultural products, such as sulfur-coated urea. The scarcity of land for producing food will further create demand for specialized fertilizers such as SCU in order to meet the rising need for food due to a growing population.

According To Coherent Market Insights, The Global Sulfur Coated Urea Market Is Projected To Surpass US$ 1200 Million By The End Of 2027, In Terms Of Revenue, Growing At CAGR Of 3.2% During The Forecast Period (2020 To 2027).

One of the first CRFs was sulfur-coated urea (SCU). The Tennessee Valley Authority manufactured it. SCU was created by coating preheated urea granules with molten sulphur, an elemental sulphur. Because of its ability to melt at approximately 156°C, sulphur is a low-cost plant macronutrient that is suitable for fertiliser coating. According to Jarrell et al., a typical SCU granule was composed of three types of coatings. Spraying molten sulphur over urea enabled the basic coating. Following that, a wax sealant is sprayed to seal the crack in the coating. The wax sealant acts as an excellent protective layer, reducing microbial degradation.
