It is well documented that there is a major shortfall in the volume of lime being applied on an annual basis. Current application rates are less than half of the annual application rate of 1.7m tonnes applied in the 70s and 80s. This is despite lime having the ability to greatly enhance the biology of soil and generate a return in investment of 7:1.

To put this in terms of output, increasing soil pH to the optimum level can underpin an increase in grass growth rate of 1t to 1.5t DM/ha.
