Foliar Feed

[David R. Hershey]

Foliar feeding is usually only done in specialized situations, such as 
iron deficiency, where the plant cannot get enough of a nutrient via root 
uptake. It is also sometimes used in agricultural situations to give a 
crop a "boost" or to prevent a nutrient deficiency. It is not very 
efficient because leaves are not designed for absorption of nutrients, 
the roots are.
