Urea is the most important nitrogenous fertilizer in the market, with the highest Nitrogen content (about 46 percent). It is a white crystalline organic chemical compound. Urea is neutral in pH and can adapt to almost all kinds of soils. The main function of Urea fertilizer is to provide the plants with nitrogen to promote green leafy growth and make the plants look lush. Urea also aids the photosynthesis process of plants. Since urea fertilizer can provide only nitrogen and not phosphorus or potassium, it’s primarily used for bloom growth.
