Description
CALCIUM SULPHATE ASX is a mineral, granulated and dusty sulphur-calcium fertiliser. It is intended for fertilising arable crops, vegetables, and fruit trees and shrubs.
Calcium and sulphur are well soluble in water and easily available to plants. The fertiliser effectively eliminates deficiencies of these nutrients.
CALCIUM SULPHATE ASX - Chemical composition:
- Total calcium oxide (CaO) (31%);
- Water-soluble calcium oxide (CaO) (30%)
- Sulphur trioxide (SO3) total (45%)
- Water-soluble sulphur trioxide (43%)

Apply the fertiliser pre-sowing, preferably in a set of post-harvest cultivations or top dressing, evenly over the entire crop area, in rows or in bands. In orchard crops, apply the fertiliser after fruit harvest or very early in spring. Fertiliser doses are best determined based on soil analyses and the nutrient requirements of the cultivated plant.
