Make an effort to keep the fertility of soil. By adding lime to acidic soil, we can achieve greater quality of produce
Dolomite – A calcium magnesium carbonate
REGULATOR AND NEUTRALISER OF ACIDIC SOIL RICH IN CALCIUM AND MAGNESIUM
WHY USE DOLOMITE?
- IT IS AN ALL-NATURAL MATERIAL
- Increases and regulates the pH level of acidic foil
- It is a good source of CALCIUM and MAGNESIUM for plants
- It sustains the proper development of soil life – especially earthworms
- Improves the absorption of important plant nutrients (nitrogen, phosphorus, potassium) for plants which grow in acidic soil
- On intensively used pastures there is a decrease in the occurrence of grass tetany in cattle and sheep due to magnesium deficiency in fodder
- To ensure that some types of vines get the highly important nutrient – magnesium in vineyards

Soil is characterised by its ascribed pH value, which is one of the most important qualities for the fertility of soil.
| Type of soil | pH |
| Alkaline (basic) | over 7 |
| Neutral | 7 |
| Acidic | under 7 |
The required amount of dolomite is dependent upon the pH value and texture of the soil as well as the type of plants grown on the land.
The required amount of dolomite ranges from 2.5 tons per acre to 20 tons per acre.
Approximate required amounts of dolomite with reference to the pH value of the soil:
| pH | t/ac | ||
| Sand soil | Loam soil | Clay soil | |
| 6 | 2,5 | 4 | 5 |
| 5,5 | 5 | 8 | 10 |
| 5 | 7,5 | 12 | 15 |
| 4,5 | 10 | 16 | 20 |
| 4 | 12,5 | 20 | 25 |
WE RECOMMEND that you determine the pH value of the soil in advance. The analysis can be done by an authorised institution, where they will also provide you with fertilizing advice for adding lime to the soil.
The importance of calcium in the soil for the proper growth of plants:
CALCIUM ensures the balanced growth of sprouting plants and serves as a basic building block of plant cell membranes and cell walls. Plants with many leaves require more calcium. The first signs of calcium deficiency in plants are visible on small parts of the plant: the colour of leaves fades, they may become twisted or curly and the roots do not continue to grow.
The importance of magnesium in the soil for the proper growth of plants:
MAGNESIUM helps form chlorophyll – the green colorant of leaves. Magnesium deficiency causes the discoloration of the intravenous area from the edge of the leaf towards the inner part.
