    Availble in two forms – Soil Life and Gypsum Natural

  • USES

    Gypsum is used as a source of soluble calcium and sulphate, with the added advantage of not increasing soil pH (in contrast to lime as a calcium source). Gypsum is typically used in horticulture e.g. kiwifruit, apples and pipfruit production as well as for market gardening.

  • APPLICATION

    Typical spreading rates for Gypsum are between 500 - 2500 kg/ha. Gypsum is often used in mixes, and which type of Gypsum to use in a mix can usually be determined by whether a customer wants Bulk product or Bagged.

    Actual spreading rates will vary according to farm type, climate, productivity, soil type and crop type.  Soil testing and fertiliser plans are available to ensure you use the right product at the correct rate.  Call our Customer Centre for information.

    As with most solid fertilisers, Gypsum can be stored over a season as long as it is kept in a cool, dry, well ventilated area. Store bags in a dry place ensuring they are tightly sealed.

  • ANIMAL HEALTH

    Gypsum can be used as a calcium supplement, in the same manner as Lime Flour, to prevent calcium deficiency (hypocalcaemia or milk fever) in lactating dairy cows after calving. DO NOT FEED TO PREGNANT COWS IN THE LAST 2 MONTHS OF PREGNANCY, unless under veterinary advice. Dose rate would be 100-500 grams/cow/day, typically by pasture dusting.
