Arable Crops

LimeX is used widely in arable rotations, particularly where acid-sensitive crops are grown, such as sugar beet.

The fine particle size gives excellent reactivity and rate of pH correction. A recent reactivity comparison undertaken by British Sugar demonstrated LimeX70 to be significantly more reactive than competitor products. Other replicated trials in sugar beet have shown that an application of LimeX70 can increase yield by around 20% where pH is below its optimum level.

Furthermore, research undertaken by the Agricultural Lime Association (ALA) has shown the following responses during a trial to raise pH levels from 5.1 to >6.5 :

Yield Response

Following lime treatment (ALA study)

  Yield response to 1pH unit increase
Year 1 9.2 (sugar beet)
Year 2 0.7 (spring barley)
Year 3 3.6 (sugar beet)
Year 4 0 (spring wheat)

Source: “Agricultural lime – the natural solution” (ALA 2000)
Note: Reference the above ALA study, it should be recognised that sugar beet cannot be grown in a rotation frequency of less than one in three years.

Cereals, whilst less sensitive to pH are, nonetheless, highly sensitive to sub-optimal pH. In a long-term experiment at Rothamsted, results showed that a drop of one pH unit in barley, from pH 6.5 to 5.5, resulted in a 2 tonne/ha yield penalty (source: Johnston and Whinham (1980); Archer (1985).

Nutrients

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).

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.

LimeX

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.
