Nitrogen

Nitrogen occurs in the soil and in the atmosphere and is usually provided to the plant in the form of fertiliser. In plants, Nitrogen is responsible for good vegetative growth as it promotes photosynthesis. A nitrogen deficiency can therefore be recognised by leaves that have a pale green appearance. The Department of Agriculture advises that in the case of maize and grain sorghum, an inverted V-shaped pattern on the leaf tips is an indication of a nitrogen deficiency.

Phosphates

Phosphorus has a significant role in plant growth. That is, phosphorus assists the conversion of nutrients for use in the plant. It is also one of the main three nutrients most commonly found in fertilizers. Farmers who pay special attention to managing phosphorus enjoy profitable crop production.
