Soil Nutrients

Elements essential for plant growth

These are normally divided into two groups named major nutrients and minor nutrients according to the quantities required by the plant

Major nutrients ,Nutrient Chemical Symbol ,Importance to Plants Natural Source .

Nitrogen N Synthesis of proteins, chlorophyll Plant residues
Phosphorus P Synthesis of enzymes and the storage of energy. Little natural reserves in the UK.

Potassium K Control of water by osmosis.

Much of UK soil, particularly where derived from igneous rocks, have a good reserve.

Calcium Ca Cell wall synthess, enzyme activity. Vast reserves in calcareous (chalk) soil.

Magnesium Mg Chlorophyll synthesis Reserves in magnesium limestone.

Sulphur S Synthesis of some amino acids (the building blocks for proteins). Rocks and organic material.


There are also three other important macronutrients which may be considered separately

Carbon C Synthesis of carbohydrates for strengthening and storage. Carbon dioxide in the air.

Hydrogen H Synthesis of carbohydrates for strengthening and storage. Water.

Oxygen O Synthesis of carbohydrates for strengthening and storage. Air.

Boron Bo Cell division

Manganese Mn Activation of some enzymes

Copper Cu Synthesis of some enzymes important in photosynthesis

Iron Fe Synthesis of chlorophyll, enzyme activity.

Molybdenum Mo Nitrate fixation

Zinc Zn Some enzymes

Cobalt Co

Chlorine Cl Photosynthesis

Silicon Si


There is also a group of nutrients which are not needed by plants but are essential to the horse:

Selenium, Iodine, Chromium, Flourine
