Granular Urea, is a single-element fertilizer, that supplies the major essential element nitrogen in ammonic form (NH₄+). There are two forms of nitrogen that can be absorbed by plants and trees: NO3- and NH₄+. Granular urea is the richest source of Nitrogen (NH₄+). It is a cost-effective form of Nitrogen that can significantly reduce input costs. Granular urea is applied early in the growing season when soil is moist and temperatures are warm. Losses can be reduced by rapid incorporation of it into the soil by applying before rain and using low rate applications 40kg per ha. Urea requires moisture to work and should not be used on very dry land or during the summer months.
