Field Brassicas

Intensive field brassica crops can be at risk of clubroot. Dormant spores may rest for up to two decades before striking at valuable crops immediately after planting, causing uneven maturity, reduced yield and low quality.

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)
Total P2O5 10* 7
Total MgO 7 5
Total SO3 12 9

At a minimum application rate of 10 tonne/ hectare (4t/acre) of LimeX70 the combined value of these integral nutrients is over £130 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).

Benefits of using Limex

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.

*Organised and jointly funded by the Fertiliser Manufacturers' Association (FMA), the Department for Environment, Food and Rural Affairs (DEFRA) and the Scottish Executive Rural Affairs.


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.
