FERTILIZER

In the broad sense, fertilizer refers to any materials that can increase soil fertility and crop production or quality. Generally, fertilizer can be classified into three classes: organic fertilizer, chemical fertilizer, biofertilizer.

In the narrow sense, fertilizer refers to substances that can supply plants with nutrient elements, namely carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), sulfur (S), potassium (K), calcium (Ca), magnesium (Mg), iron ( Fe), manganese (Mn), copper (Cu), zinc (Zn), boron (B), molybdenum (Mo),chlorine (CI), etc.

These elements are called the “essential elements of plants.” Among those elements, only carbon, hydrogen, and oxygen are from carbon dioxide (CO₂) and water (H₂O); the rest of them are from the nutrient elements of soil. In addition, some other elements are not essential for the plants’ growth, but beneficial to it.

They are called “beneficial elements.” For instance, sodium (Na) is beneficial to the halophytes for adjusting cell osmotic pressure; silicon (Si) can strengthen cell walls and improve plant strength, health, productivity, and disease resistance of hydrophilous and grass family plants; cobalt (Co) can improve the nitrogen fixation of the legumes plants root nodule; nickel (Ni) is essential for urea to hydrolyze enzyme; and vanadium (V) can promote plant growth, etc.
