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 two classes: organic fertilizer and  chemical fertilizer.

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.

From the classification of organic and chemical, there is a technology of combining both organic and chemical fertilizer content. With the organic presence, a large range of microorganisms can be include into the fertilizer. All Cosmos Industries is a leading manufacturer and marketer of Bio-Organic and Bio-Chemical fertilizers under the brand RealStrong. RealStrong fertilizer used beneficial microbes and combining both chemical and organic to become bio-fertilizer.
