Fertilizers

Im sure you must be asking the question of what are fertilizers? What are they used for? Must I use them? and which one must I use?

 

Fertilizers enhance the growth of plants. This goal is met in two ways, the traditional one being additives that provide nutrients. The second mode by some fertilizers act is to enhance the effectiveness of the soil by modifying its water retention and aeration.

  • three main macronutrients:
    • Nitrogen (N): leaf growth;
    • Phosphorus (P): Development of roots, flowers, seeds, fruit;
    • Potassium (K): Strong stem growth, movement of water in plants, promotion of flowering and fruiting;
  • three secondary macronutrients: calcium (Ca), magnesium (Mg), and sulphur (S);
  • micronutrients: copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), zinc (Zn), boron (B)

The nutrients required for healthy plant life are classified according to the elements, but the elements are not used as fertilizers. Instead compounds containing these elements are the basis of fertilisers. Plants are made up of four main elements: hydrogen, oxygen, carbon, and nitrogen. Carbon, hydrogen and oxygen are widely available as water and carbon dioxide. Although nitrogen makes up most of the atmosphere, it is in a form that is unavailable to plants. Nitrogen is the most important fertilizer since nitrogen is present in proteins, DNA and other components. To be nutritious to plants, nitrogen must be made available in a "fixed" form.

The four common types of fertilizers available are:

 

Chemical fertilizers

Organic fertilizers

Slow release fertilizers

Water soluble fertilizers
