Nature of Sulphur Coated Urea
Sulphur Coated Urea (S.C.U) is a fertilizer which is produced through the encapsulation of urea with elements appropriate to soil such as Sealant Sulphur which comprise of several other elements and is capable of slow release of urea nutrients within a period of 40 days due to its specific formulation. Absorption rate of nutrients available in fertilizers can be optimized through the chemical methods including the reduction of solubility or mechanical methods including the encapsulation of fertilizers. Consequently, the consumption rate of fertilizer would be decreased down to one third compared with non-encapsulated fertilizer which offers a great economic advantage. Sulphur Coated Urea provided up to 70% saving in the consumption of fertilizer and reduction of work force costs and therefore is one of the most well-known sources for the supply of nitrogen in humid areas of the world.
Demand for Sulphur Coated Urea (S.C.U)
has increased over time which can be attributed to the following advantages:
• Sulphur Coating increases the availability of nitrogen for the plants.
• Sulphur Coating increases the resistance of fertilizer to leaching and washing.
• Sulphur Coating decreases the chance of burning due to the excessive use of fertilizer.
• Sulphur Coating promotes the microbial and bacterial activity in the soil.
• Sulphur Coating increases the product can be up at least 15%.
• Sulphur Coating provides the plant with its necessary sulphur.
• Sulphur Coating increases the resistance of the plant to drought.
• Sulphur Coating impedes the outbreak of diseases due to its anti-fungal properties.
• Sulphur Coating impedes the pollution of under-ground water and boosts the efficiency of fertilizer consumption.
• Sulphur is regarded as a pesticide as well as a fertilizer for boosting the economic value and quality of the product. Therefore choosing S.C.U, we actually have utilized two types of fertilizer.
• Using non-coated urea fertilizer may lead to hardened and non-permeable soil and decline of productivity. While this problem can be addressed using S.C.U due to slow release of nitrogen in water.
• Due to the presence of sulphur in S.C.U as the main constituent (coating) and availability of its breaking down bacteria in formula of coating, sulphur operates as a nutrient and pH regulator in soil and improve the fertility of soil after the complete delivery of nitrogen to the plant.
• One bag of Sulphur Coated Urea (S.C.U) fertilizer equals to 2.5 bag of non-coated urea fertilizer in terms of efficiency.
• Rapid leaching of nitrogen when consuming non-coated urea fertilizer has caused considerable economic losses and facilitated the entrance of nitrate to under-ground waters and rivers and lead to the pollution of environment specially drinking water.
• Leached nitrogen which finally turns to nitrate causes various diseases including death in children due to deoxygenating of lungs. Whereas this problem can be solved through the use of Sulphur Coated Urea (S.C.U) fertilizer because of slow transfer to and complete absorption by plant and eliminating the chance of nitrogen loss.
