In sandy loam, the approximate amount of lime required to raise the pH of your ground to a depth of 600mm (2ft) by one pH unit (eg. to go from 6.5 to 7.5) would be 1.5 to 2.0 tonnes per hectare.
In heavier clay soils, you will probably need at least twice as much lime to raise the pH level by one unit.
Lime is relatively inexpensive and used effectively, your investment will bring excellent returns over many years.
Lime has been proven to increase farm profits and sustainability by decreasing soil degradation. Agricultural lime has always been a stalwart of fertilisers and soil conditioning products. Long known for its ability to reduce soil acidity (increase Ph) and repair non-wetting soils. It is only now coming into view that the type of lime used, whether it be lime sand, lime stone or coral lime, can make a sizeable difference in the speed and efficacy of the limes effect on the soil.
