What is the difference between NPK and urea?
Also, what is meaning of NPK?
NPK stands for "nitrogen, phosphorus, and potassium," the three nutrients that compose complete fertilizers. You may encounter these letters when reading the contents printed on bags of fertilizer.
Secondly, what is the use of urea fertilizer? 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.
Herein, what form of nitrogen is urea?
Ammonical form of nitrogen is however, easily covertible into nitrate form. Most of the fertilizers contain nitrogen in these two available forms. Urea, however, contains nitrogen in amide form but this form of nitrogen is swiftly converted by soil micro-organisms into ammonical form and then into nitrate form.
How does urea affect plant growth?
Impurities and Improper Use of Urea Fertilizers Can Damage Plants. As with any source of nitrogen, urea itself can damage plants: nitrogen impairs or completely impedes seed germination, and too much nitrogen can give crops a “burn.”
