improved soil structure

Catalogue: Ground Cover
Primary Industries and Regions South Australia (PIRSA) soil and land management consultant David Davenport, from the department's Rural Solutions SA division, says there are at least one million hectares of land in SA alone that would benefit from amelioration of sandy soils... "Sandy soils have several known constraints including water repellence, compaction, low fertility and low water-holding capacity," he says... Mr Davenport says there are a range of different amelioration options that growers can use to overcome one or more of these constraints including spading, deep nutrition, incorporation of organic matter and the addition of clay...

Maintaining and increasing the level of organic carbon in the soil will have benefits in terms of maximising water-holding capacity and crop productivity but farmers should not expect large returns from carbon credits... increase soil organic carbon (soc) by retaining crop residues, green manuring or cover cropping and reducing stocking rates on cropping paddocks... If carbon offsets were valued at $20/tonne of carbon, then the payments would be $2-3/ha and likely to be less than the cost of monitoring and administering a carbon credit program...
