Crop nutrient requirements

Know your crop’s nutrition needs and select the most appropriate fertiliser.

Plants need various elements in order to live and grow. Macro-nutrients – such as nitrogen, phosphorus, potassium, calcium and sulphur – must be supplied by the soil or from fertiliser. In addition, plants require minute quantities of certain micro-nutrients (trace elements), including molybdenum, copper, zinc, manganese, boron, and iron.

Deficiencies or imbalances in the supply of any of these essential elements can compromise growth, affecting root development, cell division, crop quality, crop yield and resistance to disease and drought.
