Macro, meso and micro elements

  • Whastsapp

Soil nutrients come in three basic categories: macro, meso and micro elements.

  • Macro elements are nitrogen (N), phosphorus (P), potassium (K).
  • Meso elements are magnesium (Mg), calcium (Ca) and sulphur (S).
  • Micro elements or trace elements are iron (Fe), manganese (Mn), zinc (Zn), boron (B), copper (Cu), molybdenum (Mo) and silicon (Si).

In order for growth to occur there has to be a proper balance between these categories. The table gives you an idea of the optimum nutrient element ratios in plant tissue.

Element Ratio in plant tissue
Molybdenum 1
Copper 100
Manganese 1000
Calcium 100,000
Nitrogen 1,000,000
