Benefits of Lime
Unless steps are taken to redress the balance of soils by applying lime material there will be a natural reduction in the lime status of most soils, resulting in increased acidity and reduction in soil fertility.
Benefits of Lime:
There are very few products that readily available and cheap that have such an effective impact of crop productivity as the application of lime does.
The application of lime compared with the application of fertilisers despite taking longer to show effectiveness, lime offers a long term solution and makes a tremendous difference to the productivity of arable and grassland.
It is key that the correct pH is maintained for the following reasons:
- Crops will not reach their full potential in acidic ground therefore the application of lime reduces soil acidity and brings back the correct pH levels
- The correct pH increases the levels of key plant nutrients in the soil
- Having the correct pH promotes the soil biology and can result the release of nitrogen by the enhancement of the organic matter cycle in the soil.
As soil types varies across the field, therefore the advantages of variable rate lime spreading can promote the benefits even more.
When should lime be applied:
Liming may be carried out at any time providing that the ground conditions are suitable.
For arable land, lime is usally applied when the land is available after cropping, it is important to allow sufficient time for the soil to adjust to the correct pH before sowing.
