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

Nutrient

Importance to Plants

Natural Source

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.


Micronutrients


Nutrient

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
