Agricultural urea

Agricultural urea is highly soluble in water, so it is quickly decomposed by microorganisms in the soil into ammonia (NH₃) and ammonium ions (NH₄⁺), which are easily absorbed by plants. Compared to other nitrogen fertilizers (such as ammonium nitrate and ammonium sulfate), it is cheaper, has less impact on soil pH, and can be applied to a certain amount of crops, making it easier to use on soil.
