GYPSUM FOR ARABLE
Gypsum for arable
– recycled Calcium Sulphate (CaSO4. 2H2O) containing 19% Calcium and 22% Sulphur.
A highly consistent, free flowing spreadable product with a highly accredited purity level. Acid soils are naturally low in Calcium therefore where additional Calcium is needed; gypsum is an ideal source for these crops. Potatoes and carrots are often grown in acidic soils to control common scab and cavity spot. In these conditions gypsum will help prevent common scab and reduce cavity spot and improve the skin quality.
The product has a unique blend of properties that contribute positively to the Cation Exchange Capacity (CEC) and nutrient storage in the soil. This relationship between the elements of Calcium, Magnesium, Potassium and Sodium as positively charged ions plays a very important role in modern day crop production. In potato and carrot production we have successfully seen a series of benefits to our customers.
Our product is recognised and accredited by the Soil Association for use in Organic Crop Production.
Gypsum is highly soluble, therefore it is an excellent source of calcium and sulphur, especially on acid loving crops.
Gypsum has been widely used in global agriculture for many years principally to:
- Add calcium without raising the pH of the soil
- For crops that require higher levels of Sulphur and / or Calcium
- On light sandy soils that do not hold nutrients
- On crops that require acidic soils
- To obtain calcium and sulphur in their most soluble form
- To improve the calcium / magnesium ratio
- To correct salt damage
- To help in waterlogged areas
Gypsum has been used to improve soil structure. The calcium in the gypsum increases the ability of the soil particles to flocculate. This is the formation of small crumbs in the soil structure which is needed for good rooting, drainage and nutrient uptake.
For land which has a high magnesium content the application of Gypsum has transformed the soil properties to enable a dramatic reduction in the required horse power to work the soils more easily.
