Phosphorous is essential for the health of lawn grass as well as other plants in the garden. Slow growth, dead patches of lawn and burnt looking grass can be a symptom.

Did You Know
Because phosphorous absorption can be strongly influenced by the pH (acidity - alkalinity) of the soil, check the pH. To make phosphorous most available to the plants adjust the pH to neutral or slightly acidic, pH6.0 - 7.0.
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).
