"Farmers have embraced conservation agriculture because it makes good sense to protect the soil, conserve water and save time, labour and fuel," he said... Factors that detracted from the benefits of conservation agriculture in Australia included weeds, root disease and inhibitory soil organisms that could slow early crop growth and reduce yields... Dr Kirkegaard said soil disturbance could be required to incorporate these inorganic nutrients below the soil surface where they can stabilise carbon, allowing it to build up in the soil...

Philanthropists are helping to reverse declining funding for international agricultural research, with important flow-on benefits for Australian grain growers... The broader benefit for all grain growers was also talked about by Carlos Slim (a Mexican business magnate) at the inauguration ceremony: "This alliance to promote research and development by CIMMYT, with the collaboration of national and international scientists dedicated to improved seed and generating more efficient techniques, is a step toward making this knowledge available to farmers everywhere, particularly small and intermediate-scale farmers, as well as promoting economic growth, employment, and food self-sufficiency and exports from this sector," he said... Valentin Dvurechenskii, director-general of the Kostanay Agricultural Research Institute, says that, overall, zero-tillage has helped to nearly double average wheat yields, from 1.4 to 2.6t/ha...

And I would suggest that at least in the area of driving farming production forward their government would be miles front of our own... GPS technology is widely used throughout Argentina, close to 100% in areas... We had a very lengthy discussion about mining nutrition using our liquid fertiliser philosophy, until I suggested that with their 120 kg/ha of DAP and 100 units of N to grow 20 t/ha, they were probably mining more than we were...

The system may allow continual cropping but it does not really allow the soil to fully recover... I always believed that wild radish germinated because we cultivated the soil... If we are going to use plants to improve our soil structure then we need those plants to grow at their maximum potential...

Related research undertaken by WANTFA examined the economic performance of several conservation farming strategies... As a result of research conducted in this project and related research managed by WANTFA, growers can adopt more sustainable farming strategies based on better knowledge of the impacts on the resource base... The specific aim of this research project was to collaborate with WANTFA staff to quantify the water balance impacts of the inclusion of cover crops and higher levels of residue retention...

A study of zero-till innovations in Argentina has identified technology that also has the potential to improve crop establishment and yields for Australian growers... Mr Gould says for every extra 100mm of stored moisture in a rainfall zone of 600 to 650mm, typical zero-till growers visited in Argentina are achieving an extra 1700 kilograms per hectare of maize, 1400kg/ha of sorghum, 800kg/ha of wheat and 650kg/ha of soybeans... Mr Gould says strong and well-coordinated links between government agencies and researchers, machinery manufacturers, extension providers and the commercial sector are central to the success of zero-till in Argentina...
