Fertilizer product designed to be applied directly to the leaves of a plant commonly by spraying.

Specialty fertilizers are distinct from the commodity fertilizer products like urea, diammonium phosphate (DAP) and muriate of potash (MOP) or blends of these in that they are generally less commoditized, have “designer” characteristics and are of higher unit value.

Various forms of other fertilisers are used in farming and gardening to increase the yields and combat diseases and other undesired conditions.
