Crop resilience patiently built on soil health.. Stuart says on-farm trials over the past eight years show that inputs costs equate to one tonne of a two tonne per hectare crop but 2t of a 3t/ha crop... "The results show more nitrogen, phosphorus and potassium are available when organic matter is introduced, and that there is more stored water in the top 10cm and no limit to the number of microbes, provided there is sufficient organic carbon," Stuart says...

The scheme is expected to cost some industries and benefit others, with profits possible for those that can trap (sequester) carbon or substantially reduce current carbon emission levels... Each company in the scheme will have an emissions target set for them, which can be met by reducing emissions or buying carbon credits... Experts predict that because of this, agriculture will be managed upstream and downstream: products will be assessed under the scheme at a point in the sale chain (for example, at the abattoirs for stock) and inputs will be assessed prior to use (for example, diesel and agri-chemicals)...

Author/s: Dr Mike Bell and Dr Davie Lawrence Publication number: PR09-4345 Published: 31 March 2009 Bibliographic details: 6pp, forms of organic matter and carbon, carbon accumulation.. The report describes the various forms of organic matter in soils, how soils can act as a sink for carbon and how it can be measured, and the role organic matter plays in determining soil functions and properties... Greatest benefits can be gained from increasing the inputs of carbon and organic matter to soils by growing better crops and pastures more often...

Consider using only post-emergence herbicides when controlling weeds in mouldboard ploughed soils for some years after ploughing.. Mouldboard ploughing can affect the phytotoxicity of soil-active herbicides and hinder crop germination, research is finding.. Researchers Derk Bakker and Grey Poulish from the Department of Agriculture and Food, Western Australia (DAFWA), at Albany say several trials stood out because of the substantive failure of seed to germinate where cereals and canola were sown in the mouldboard ploughed plots on white sand and on coarse sandy gravel...

Understand the factors that affect mineralisation.. The rate of mineralisation varies with soil temperature, water content and, depending on the soil type, it can vary with the amount of organic matter and residues, and pH - mineralisation is slower in acidic soils... During the growing season, the amount of mineralisation is reasonably predictable and models are available that will estimate mineralisation over time periods ranging from days to years...

Research is showing that up to 1.6 million tonnes of carbon a year could be being stripped from agricultural soils by wind erosion... Leading the research, Dr Raphael Viscarra Rossel says the map, showing soil organic carbon stocks for every 90 metre square block across the country to a depth of 30 centimetres, with estimates of uncertainty, draws on soil sampling data, including the GRDC-funded Soil Carbon Research Program... "The map provides a reliable benchmark for monitoring the influence that changes in land cover, climate, land management and greenhouse gases have on soil carbon and carbon dioxide removal from the atmosphere," Dr Viscarra Rossel says...
