It is a viable (though somewhat controversial) means of enhancing crop nutrition. Foliar fertilization is a tool used in both conventional and alternative production systems. This publication covers the basics of foliar feeding, discusses formulation of foliar sprays, and addresses component fertilizers for foliar fertilization.
