Aerial top dressing with Super Ag Gypsum

December 12th, 2009|

Regyp Super Ag Gypsum is more suitable to aerial top dressing due to the material handling properties, spreadability (similar to prilled products) and the increased solubility. In general aerial top-dressing contractors, to tend to use coarser gypsum material to overcome material handling issues and also to deliver the recommended quantities more quickly. The influence of

Effect of gypsum on topsoils

October 14th, 2009|

Gypsum improves the soil structure of hardsetting or crusting sodic clay topsoils, not only by reducing swelling, but also preventing clay dispersion. Sodic topsoil (0-10cm) usually has very poor structure – it is waterlogged when wet and too hard when dry. Sodic soil has too much sodium linking clay particles and not enough calcium. Sodic

Improving soil structure with gypsum

October 14th, 2009|

Gypsum works on improving spoil structure in two ways. Both depend upon the gypsum being dissolved by rain or irrigation water and entering the soil solution. The first is called the electrolyte effect which is based on the fact that swelling and clay dispersion of sodic clay soils decrease as the salinity of water infiltrating
