Polymer + Sulphur - COATING TECHNOLOGY
HARACOAT PSCU is made by coating urea with sulphur and polymer coatings, the amount of which will determine the product’s nitrogen release characteristics. The dual coating layers are biodegradable, flexible and provide good controlled release.
Nitrogen supply is continuous and stable, slower in cooler conditions, faster when warmer. The same conditions that control plant growth rates apply to the N release from Haracoat.
In the soil environment, the urea is gradually diffused through the imperfections in the coating such as minute cracks, pinholes and incomplete coating structure to achieve this slow release effect. Haracoat has three release phases. The first will start immediate N release upon exposure to water; the second releases N after a
few weeks and the third provides longer release to provide later N requirements of the crop or pasture.
Longevity is determined by the thickness of the sulphur coating and the amount of polymer sealant, all of which is determined by soil temperature and moisture.
