Organic and inorganic foliar feeds have their place in plant nutrition. Most organic foliar fertilisers will provide the necessary macro-nutrients but quantity and efficiency will vary, depending on the materials used for their preparation.
Inorganic foliar fertiliser, on the other hand, is specific in the nutrients provided and quantity. In particular, most micro-nutrients such as zinc and iron will require to be chelated through complex chemical processes to be available to the plants.
The chelated micro-nutrients are found in inorganic foliar formulations.
