Granular Fertiliser

Apply lime as required to increase soil pH up to target pH for the crop. Maintaining the
soil pH at the optimum level will increase the microbiological activity of the soil, and
result in better soil nutrient recycling and release. Soil pH is also critical for maximising
the availability of nutrients applied in organic and chemical fertilizers.
The first thing to get right is soil pH, if soil test results show a lime requirement.
Lime should be applied to neutralise acidity and raise the pH.

Over-liming can be an issue in some circumstances, especially in grassland where there is
a history of high molybdenum (Mo) in soils. It is advised not to raise the pH above 6.2 in
these circumstances, as high Mo can cause copper deficiency in animals.

Most importantly do not to apply too much lime in a single application, as it can make
some trace elements unavailable.

The aim of P and K nutrient advice is to maintain all fields at the optimum soil fertility
level. The soil test measures the plant available P and K in mg/L of soil. For simplicity, this
result can be categorised into a soil Index for each nutrient. The soil Index system divides
soils into one of four soil Index levels based on the soil test result. The soil Index indicates
the expected response to nutrients applied. For example Index 1 soils are very responsive
while Index 4 soils have sufficient soil nutrient reserves and usually do not respond to
fresh P and K applications
