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 :

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 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.
| Nutrient |
LimeX70 (kg/tonne) |
LimeX45 (kg/tonne) |
 |
| Total P2O5 |

| Total MgO |

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).
