Complete List and Importance of Chemical Fertilizers for Crops

1) Nitrogenous Fertilizers The nitrogen in many straight and compound fertilizers is in the ammonium (NH₄ ions) form, but this is quickly changed by the bacteria in the soil to the nitrate (NO₂ ions) form. Most crop plants such as cereals take up and respond to the NO₃ ions faster than to the NH₄ ions, but some crops, such as rice, potatoes and grasses, are equally responsive to both forms. On the basis of the chemical form in which nitrogen is combined with other element in a fertilizer, nitrogenous fertilizers…
