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.

These detrimental effects of clubroot can be managed by active husbandry to modify the environmental factors that favours the pathogen, principally soil acidity, calcium deficiency and poor drainage.
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)|
At a minimum application rate of 10 tonne/ hectare (4t/acre) of LimeX70 the combined value of these integral nutrients is over £145 per hectare (inclusive of the savings in applying individual nutrients).
Due to the exceptional process conditions created as a result of the
prolonged wet and then cold and wet weather during the latter half of
the 2012/13 processing season it was necessary to increase lime use to
varying extents in our factories to maintain throughput.
As a result this has affected the total P2O5 content in LimeX70 produced at Newark and Wissington.
Please be aware that we are unable to declare 1.0% minimum P2O5 content for Newark and Wissington product until new season (2013/14) product becomes available.
Our revised values for product to be dispatched are now 0.9% P2O5 for Newark and 0.7% P2O5 for Wissington.

Geoff Dixon, Research Professor in Horticulture, University of Strathclyde, reports:
'Field studies on heavier silt soils around Boston, Lincolnshire since 1998 have demonstrated that applications of LimeX diminish the impact of clubroot. The big advantage of LimeX is its rapid action. Applications can be made in early spring and can raise soil alkalinity from pH 6.8 to pH 7.5 very quickly.'
