Ferrous sulphate heptahydrate is a source of iron. It is commonly used in turf culture as a moss killing agent.

 

Iron deficiency in pasture & crops is rare.  Where there is a deficiency it is usually related to low pH and poor drainage and most deficiencies are rectified by addressing these problems rather than by addition of Iron.

 

It is also occasionally used as a soil acidifying agent.

 

Ferrous Sulphate is water soluble so it can be sprayed onto marginally deficient crops if necessary.

 

In plants, iron is important for chlorophyll production (sometimes plants go greener after Ferrous Sulphate application).  It is required for enzymes involved in photosysnthesis and respiration.

 

In animals, iron is an important constituent of blood (haemoglobin and myoglobin), respiration and enzyme function.
