soil organic carbon

Catalogue: Ground Cover
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...

Farming systems which minimise the movement of soil and water will also minimise the loss of nutrients and pesticides... Overall, the only large difference was the lower Zn when superphosphate was applied... In summary, Mike has found a strategy to help him interpret his yield maps - and is now taking the same approach to other paddocks to maximise fertiliser savings...

Researcher's Name: Dr David Minkey Organisation: University of Western Australia Email: david.minkey@wantfa.com.au Phone: 0417999304 Fax: 0417999304 Project Code: UWA00163 Contract Start: 7/1/2013 Contract End: 6/30/2016.. A situation analysis of no-tillage in Western Australia (Derpsch, 2005) recommended that soil organic carbon and crop yield and water use efficiency could be improved by changing the system to include full stubble retention, diverse rotations with cover crops and a more holistic approach to weed management... From 2010 onwards the plots were split into high and low (windrow burn) residue treatments...

I firmly believe that farmers are in the business of producing multiple commodities not just wool or wheat but are custodians of the environment not just for themselves but for society as a whole... As my knowledge expanded and my business increased I began to pass on that knowledge to farmers in an effort to encourage them to plant natives on farms... In the past we have focused as farmers on production and maximising yields...

In a recent survey 96% of growers indicated their knowledge about soil health had increased as a result of this project; 94% indicated they were better at making decisions for their business regarding soil health and 91% indicated information from the Liebe Group had been useful for changing farm practices... Professor Daniel Murphy, of UWA, analysed results from the Liebe Group's long term Soil Biology Trial, which has been measuring soil organic carbon build up since 2003, and the results of this analysis have provided growers with an indication of realistic soil organic carbon levels that can be targeted... Seven fact sheets about soil amelioration have been produced. . They contain concise and practical information to be used as starting points for growers investigating soil amelioration options...

In the short term, IWM costs more than a herbicide only approach but this should be viewed as an investment in the longer life of our herbicide resource... In the short term (at least the next 8 years), these crops will in essence provide new uses for old herbicides and old herbicide groups... In summary, the research also indicates that the public is least likely to approve of GMOs that: Benefit a company over the public; Involve gene transfer from species that are not closely related; Are not undertaken for a societal benefit; Are perceived as being possibly harmful to people or the environment; or Is a food over a non-food application...

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...
