Not a liming agent

People often make the mistake of thinking of gypsum as an alternative to liming. Gypsum is not a liming agent even though it contains calcium.  It does not affect the pH of the soil.

Proper pH is important in improving soil quality.  If pH is too high or too low, nutrients are not as available and biological activities are not as efficient. Growers still need to correct any pH issues with appropriate levels of lime.

GYPSOIL is more soluble in water than lime (about 2.5 grams per liter) so the calcium in GYPSOIL is more mobile than the calcium in lime and so it moves easily deep into the soil profile.

For soils with highly acidic subsoils, GYPSOIL can help eliminate the toxicity that is associated with high levels of exchangeable aluminum (Al3).  Generally, the lower the soil pH, the greater the concentration of soluble and available aluminum. For many plants growing in acid soils, the high levels of exchangeable aluminum prevent roots from flourishing.  Read more
