Calcifert LS11 is proven to neutralise soil acidity

An innovative new soil treatment available for the first time to UK farmers, promises to balance soil pH and supply essential sulphur to soils in one easy, cost-effective application.

Calcifert LS11 both neutralises soil to maintain a balanced pH and contains 11% SOto help address the widespread sulphur deficiency on UK farmland.

Calcifert LS11 is suitable for all cropping situations that have a requirement for both soil neutralisation and a Sulphur supply. The high percentage of Calcium Lime will optimise the soil pH, being pure high reactivity Calcium Carbonate, making more nutrients bio available. The Calcium Sulphate portion of the product will supply much needed plant available Calcium and Sulphur which are commonly undersupplied in crop nutrient management plan.

Importance of sulphur

Recent data suggests that following a dramatic reduction in atmospheric deposits over the last 30 years, up to 85% of arable land and 88% of grassland, is deficient in sulphur, with some soils now at critically low levels.  Sulphur is an essential nutrient required for the healthy development of all plants and vital to efficient nitrogen utilisation.

Calcifert LS11’s sulphur content is coupled with high reactivity calcium carbonate – making it very effective at neutralising soil acidity and maintaining the right pH level to optimise fertiliser and nutrient efficiency leading to better quality and yield of crops.

Cost-effective and improved yield

LKAB’s technical specialist and agronomist, Mark Tripney, explains more:

“With ever-increasing fertiliser prices and sourcing becoming an issue with some products, it is more important than ever that farmers get the most from the inputs they apply, and Calcifert LS11 is a quick, easy and cost-effective way to target two essential areas of soil health that need addressing annually in nearly all cropping situations – pH level maintenance and sulphur supply,” says Mark.

Calcifert LS11 trials

“Trials on one Scottish grassland farm have shown that a single spring application of just 200kg of Calcifert LS11 per hectare, improved Dry Matter yield by 9.2% between May and August. This equates to a return of 12:1 and is the result of the improved nutrient use efficiency, and plant uptake, when available calcium and sulphur are applied early in the growing season and pH is maintained at the target level,” explains Mark.

“Soil health, productivity and organic matter are under the spotlight as we look to farm in a more regenerative way, and Calcifert LS11 meets this ambition by improving soil health, and ultimately leading to fewer, more carbon-heavy inputs.”

Calcifert LS11 is suitable for all crops and is best suited to spring application but is also suitable for autumn drilled oilseed rape and grass reseeds. As with all Calcifert products, it is supplied in 600kg bags and can be spread on farms using a conventional fertiliser spreader.
