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.
