Plant Nutrients
People ask...What are the various elements of plant nutrition and what are their uses?

The three essential elements and their effect on plant growth are:

Nitrogen: this element enters into the structure of protoplasm, chlorophyll, and various plant foods; it is needed for both the vegetative and reproductive stages of growth; its use is usually manifested by and increase in vegetative growth.

Phosphorus: it is essential to cell division and for the formation of nucleoproteins; it aids root development; hastens maturity, or stiffens tissues; and stimulates flower and seed production.

Potash: necessary for the manufacture and translocation of starches and sugar; it is a general conditioner, overcoming succulence and brittleness, hastening maturity and seed production, and aiding in root development.

How to recognise nitrogen deficiency ?
The whole plant is dwarfed and the older leaves turn from green to yellow, and then to brown, and remain attached to the plant.

How can nitrogen deficiency be corrected?
Foliar Feed Fertilizers will correct the deficiency of nitrogen as well as supply phosphorus and potash.
