Dolomite is a natural mineral that contains calcium and magnesium. Research shows dolomite addition to substrates is very beneficial. We add dolomite to Orchiata to:
-
- Stabilise the substrate by increasing the pH to within a range of 5.5 to 6.5
- Prevent salt accumulation
- Provide the minerals calcium and magnesium, essential for plant growth
The dolomite in Orchiata provides the plant with an initial start up supply of these two minerals. Growers must remember though that after a good length of time (around 9 months), dolomite will have broken down and growers must reapply dolomite or other liming compounds to maintain optimum plant growth.
