Wheat plantings down
Annual wheat seed sowings in NSW are expected to be down on last year, because more farmers are switching to higher priced oil crops as the price of grain falls. The estimated 2.84 million hectares
Treatment of Irrigation Water with Gypsum
Gypsum has many uses in industry, agriculture and it can also assist in the treatment of irrigation water for operations such as the coal seam gas extraction. During Coal Seam Methane a large volume
General Gypsum Application Guidelines
Gypsum can be spread directly onto soils or added to irrigation water. Application rates are as follows: • 2.5t/ha for surface crusting soils. • 10t/ha to improve soil structure throughout the soil profile. • Applications
Victorian waste levy increase
The waste levies in Victoria are to be increased 1 July 2010 with a second increases scheduled for 1 July 2011 and levies will progressively be increased over the following four years to 2014-15. A
Gypsum spreading trials
ReGyp undertook spreader trials using the Super Ag 10mm screened gypsum product near Cowra NSW. The results off the spreader are substantial, with the Regyp gypsum spreading up to 19m (average 17-19), with various

Flocculation on construction projects
Flocculation is the process of causing small, suspended materials to stick to each other to form “flocs”. These flocs more readily settle out compared to the individual particles. When soil is exposed during civil construction,
Aerial top dressing with Super Ag Gypsum
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
Lawn Establishment Additives

Construction Pit Water Treatment
If you require to treat your excavation pit water before pumping it out, you may need to treat the water with gypsum to reduce the turbidity. Treatment with REGYP gypsum can allow you to settle
Solution Grade Gypsum – What is it?
The use of gypsum(1) as a soil amendment and fertiliser has been well documented for over 200 years. Historically, gypsum has been spread over the ground using mechanical or manual methods. Depending on the situation,
FCR recycling trials
ReGyp has trialed various methods of recycling fibre cement board (FCR). ReGyp is continuing to develop this equipment and end uses for the recycled products. Fibre cement products are a mixture of cellulose fibre, cement,
Effect of gypsum on subsoils
Many soils in NSW have sodic clay subsoils of low permeability. These soils waterlog easily after heavy rain or irrigation. Under these circumstances subsoil oxygen levels remain low for long periods during which root development
Effect of gypsum on topsoils
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
Improving soil structure with gypsum
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
Sodic Soils
Sodicity should not he confused with salinity. Salinity refers to the total amount of salts dissolved in the water in soil, whereas sodicity refers to the exchangeable sodium cations bound to clay particles. Salinity can
