urea free This formula is acid forming and recommended for plants in calcareous
soil or use where alkaline water pH is high. It helps form an acid soil
condition while supplying soluble available calcium, magnesium, sulfur
and six micronutrients. If you are experiencing problems with your plants
due to calcium and/or magnesium deficiencies use of this cal-mag fertilizer
can help. We use it on our slipper orchids.
