The global recession has reduced northern hemisphere emissions to a greater level than what is legally required so there has been very little need for trades to occur... In the near future we may have a fish industry based in rural Australia operating in a similar way to the poultry industry, based on the premise that algae has unlocked the method of using cereal grains as a feedstock... A farmer may have 20 years of increase in soil carbon followed by 20 years of gradual decline despite using accepted best practises to retain soil carbon...

Subsequently a key extension publication was developed that outlines the considerations required prior to the use of animal manures and organic wastes in grain cropping systems... The research highlights that a large volume of available data exists on the use of manures and organic amendments in cropping systems... Higher rainfall cropping zones (more than 600 mm/year) have the greatest capacity to store soil carbon (18 tonnes per hectare compared with 2.5 tonnes per hectare for rainfall less than 600 mm/yr) and are more likely to positively respond to organic inputs...

The aims of the report were to observe, question and review the issues involved with carbon policy across a mix of developed and emerging countries that were involved in international negotiations... The energy sources that we need to develop include: Bio-fuels Biomass Hydro Solar Wind Marine (wave and tidal energy) Nuclear Geothermal Hydrogen & Fuel cells... Soil carbon accounting and measuring models need to be simplified to allow farming business management to engage and comply both domestically and internationally...

Grain growers in the northern region can look forward to an informative program with expert speakers at the upcoming Grains Research and Development Corporation (GRDC) Grower Updates this February and March... GRDC northern panel chairman James Clark, said four Grower Updates were being held in northern NSW and southern Queensland during February and March that would provide invaluable updates to research and farming practices... Surat, Qld - New Royal Hotel - 9 March 2012 "With a carbon tax about to be introduced, growers can't afford to miss these updates, particularly with two expert speakers who will discuss the carbon tax as well as carbon sequestration," Mr Clark said...

The latest in evidence-based scientific data on cropping soils, carbon sequestration and farming systems will be presented at the upcoming Grains Research and Development Corporation (GRDC) Update being held in Goondiwindi... World renowned expert in soil systems, Professor Iain Young from the University of New England will explore soil, plant and microbe interactions in cropping soils and provide an international perspective that advisers and growers can't afford to miss... "The Update is a chance for growers and advisers to tap into the latest research, liaise with our expert local and international guest speakers and become better informed on ways to boost productivity on farm in a more sustainable manner."..

Farmers throughout southern Australia continue to seek improved conservation farming strategies, including increased levels of residue retention, reduced soil disturbance, and greater rotation diversity... CSIRO has been monitoring changes in the water balance on the trial since then, and so far we have demonstrated that early crop termination (as part of a cover cropping practice) can increase the risk of dryland salinity under some situations... Increased levels of residue retention have had little impact on the water balance in the short term (6 years), and so farmers can adopt this practice confident that there will be no negative short-term environmental impact due to changes in the water balance...

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...

A pasture phase with legumes was found to be suitable to increase soil carbon... Stubble removal for bioenergy has manageable impacts, and is feasible in most areas provided 1-1.5 t/ha of stubble is retained for soil protection... There is notable interest in the use of multiple sources of biomass in a region for energy production...

The BettaCrop database currently has information for over 10,000 paddocks and includes over 120 current growers across northern, central and southern areas of NSW. Analysis of the database is conducted each year and is able to provide comparisons of various agronomic and management factors that contribute to achieving high water use efficiency (WUE)... The project commenced in July 2008, and will examine the effects of management practices on WUE. Soil water characteristics will be determined and WUE will be calculated and modelled for the growing season... Passioura & Angus also state that tactical management has the potential to increase yields in favourable seasons with little effect on yields in poor seasons...

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...
