clay spreading

Claying improves the productivity of sandy soils.. Despite years of clay being spread over sandy soils to improve water-holding capacity, little is known about its impact on the soils' nutrient content... As part of the GRDC-funded More Profit from Crop Nutrition (MPCN) initiative, researchers from the Department of Agriculture and Food, WA (DAFWA) and Murdoch University are exploring the potential to improve crop nutrition after claying...

Clay spreading or delving can significantly improve yields of sandy soils but it is vital that the process is performed correctly... Poor root exploration into the subsoil caused by a distinct separation between the spread/delved soil and the layer below and by not addressing fertility and low plant available water in bleached subsoils... The clay content of a soil can be estimated by taking a handful of the soil, adding water and working it into a ball until it is smooth, and then squeezing it out into a ribbon about 2-3 millimetres thick...

Delving (pictured) is effective when clay is less than 65 centimetres below the surface but clay should be spread when delving to a depth of more than 65cm... For ease of operation and to facilitate the movement of clay up the delving tyne, clay delving is best undertaken in spring while the soil still contains some moisture... When using traditional incorporation technologies, a claying rate of 150 tonnes/ha has been appropriate for many EP sites; high carbonate levels - spreading at high rates of clay that contain high levels of lime has resulted in long-term nutrient deficiencies; and clay too deep for delving - long-term wind erosion has been caused at some sites where clay material has been deeper than 65cm...

To minimise losses, a number of growers - many of whom have been practicing no-till or zero-till farming for 20 years - have been out cultivating to bring up clay clods and minimise topsoil losses... Primary Industries and Regions SA (PIRSA) soil and land management consultant David Woodard says growers who have undertaken "emergency tillage" have been cultivating just deep enough to bring up clods of clay to cover the furrow... Mr Woodard says there are certain types of clay to avoid if growers choose to practice clay spreading or delving on sandy soils to stop erosion...
