Q. Is SuperCal® the same as lime?

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.

Q. What are signs that I could benefit from using SuperCal®?

Answer: Anywhere soil or plant tissue tests shows a deficiency of calcium. Areas where plants are grown from seed come up and do not grow off well or even die. Healthy transplants not surviving under ideal conditions. Leaves that are deformed. Fruits and Vegetables getting blossom end rot before maturity. Brownheart appearing in leafy and heading vegetables. Weak plants never getting a good green color. Bitter tasting fruits and vegetables. Hard cloddy soil that becomes very sticky when wet.

Q. How much should I apply?

Answer: Application rates will vary from 5-20 ounces per 1000-sq. ft. depending upon area applied and soil type.
