Potassium encourages grass rooting and drought tolerance by improving leaf strength, improving water absorption and retention plus the resistance to heat. It is also important in disease resistance particularly to fungal disease such as fusarium and dollar spot.

The macro nutrients that plants need in relatively large quantities are nitrogen (N), sulphur (S), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg). But plants also need trace elements in small quantities for healthy growth. Trace elements include; iron (Fe), manganese (Mn), boron (B), copper (Cu), zinc (Zn) and molybdenum (Mo).
