Grassland
Grassland can be highly responsive to lime; declining pH lowers soil fertility and sward productivity as grass grows best at pH 6.0 – 6.5.
Herbage crops can deplete soils by over 1 tonne lime equivalent per annum per hectare simply through crop removal. In addition, nitrogen use and over-winter rainfall will also contribute to loss of calcium and declining soil pH, leading to a reduction in sward quality and productivity.
Liming trials conducted by the University of Newcastle upon Tyne completed in 1998 demonstrated LimeX70’s ability to raise pH more rapidly than a traditional limestone product. In addition, yield responses were highest where LimeX70 was applied, along with increases in nitrogen uptake and hence crude protein.

Nutrients
A unique advantage of LimeX70, and an important one regarding overall farm costs, is the value of the nutrients integral in the product.
The information below shows the minimum levels for three important nutrients and their value to your enterprise using RB209 7th Edition (2000) as a guide.

At a minimum application rate of 5 tonne/ hectare (2t/acre) of LimeX70 the combined value of these integral nutrients is around £100 per hectare (inclusive of the savings in applying individual nutrients). |
