Phosphate fertilizers are classified as natural phosphates, treated phosphates, by-product phosphates and chemical phosphates. * The National Fire Protection Association gave anhydrous ammonia a flammability rating of 1, or slight, and a health hazard of 3, or high. It occurs as natural deposits of rock in different countries. The class of fertilizers called nitrates could replace urea because green ammonia would be used to produce green nitrates – they contain no carbon – but also because they release less N2O (a far more powerful greenhouse gas than CO2) after being applied to the field. In addition to the three fertilizing constituents like, N, P2O5 and K2O, the oil-cakes contain 2 to 15 percent of oil. Ammonium sulphate is easy to handle and is stored well under dry conditions. It is applied during sowing or as top-dressing but never during germination. Ammonium/urea based fertilizers tend to create lush or soft growth resulting in larger leaves and darker green plants. It is a white crystalline salt, containing 20 to 21 % ammoniacal nitrogen. Fertilizer Types Although it is generally agreed that fertilizers come in three physical forms (liquid, solid and gas), there are actually only two classes of fertilizers: liquid and solid. The European slag contains 15 to 18 percent P2O5 and used as a popular phosphatic fertilizer in central Europe. In India most of the soils contain sufficient amount of potash. To overcome this difficulty it is also produced in granular pellet forms coated with a non-hygroscopic inert material. It is highly concentrated nitrogenous fertilizer containing 45 to 46% of organic nitrogen. Next in our list of 10 household uses for ammonia, is to use it as a tile … This is called the oxide form for elemental phosphorus (P), and potassium (K). Mixtures usually fulfil the nutrient deficiencies in a more balanced manner and require less labour to apply than different fertilizers used separately.
