Answer: Like limestone, SuperCal® contains calcium but that is where the similarity ends. The calcium in SuperCal® is highly soluble and “immediately” available to your plants at the time of application. SuperCal® also contains an organic chelating agent that breaks down insoluble calcium from natural limestone deposits in your soil which creates additional plant available calcium.
Q. Why not just spread limestone?
Answer: It can take 1-2 years for normal limestone to break down and benefit a soil deficient in calcium. SuperCal® works immediately.
Q. Will SuperCal® affect the pH of my soil?
Answer: Yes, as the organic acids bring more calcium into the soil solution the pH will be affected.
