A warning for farmers

• It has come to our attention that certain commercial interests are promoting the sale of gypsum to farmers for use as animal bedding in slatted units and other holding facilities.

It is also promoted for its beneficial effects on soil fertility. While there is no dispute about the latter, farmers should be warned of the dangers of using gypsum for under-bedding animals.

Gypsum (CaSO4), when washed into slurry pits, will, over time, break down under the anaerobic conditions pertaining in the pit, thus releasing hydrogen sulphide (H2S).
