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.

A unique advantage of LimeX, 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 the Fertiliser Manual (RB209 8th Edition 2010) as a guide.

Nutrient LimeX70 (Kg/tonne) LimeX45 (Kg/tonne)
Total P2O5  10*  7
Total MgO  7  5
Total SO3  12  9

At a minimum application rate of 5 tonne/ hectare (2t/acre) of LimeX70 the combined value of these integral nutrients is around £70 per hectare (inclusive of the savings in applying individual nutrients).

*Wissington LimeX70 Phosphate Content (P2O5) – updated 31/10/13

Please note a change from our standard declaration of 1.0% minimum P2O5 content for Wissington product.

The revised value is currently a minimum of 0.8% P2O5 for Wissington (ie at least 8kg P2O5/tonne).

Concern over decline of liming

The British Survey of Fertiliser Practice* suggests that the steady decline in agricultural land area receiving lime in Britain appears to be reversing slowly for arable agriculture, but for grassland agriculture it is a differerent and more worrying story – see ‘News and Events’ for more information.

The survey also concludes that this area is still considerably less than that calculated to require liming. In addition, it states the principle causes of acidification have not lessened, and it is reasonable to believe that significant areas of arable land, and more particularly grassland, are at a pH level which could limit productivity.

Proven over more than 80 years, LimeX is an easily spreadable, high-quality liming material ideal for the correction of soil acidity and general conditioning. It is suitable for agriculture, horticulture, brownfield restoration and the built environment.
