The introduction of cover crops into no-till farming systems can provide increased soil cover, add diversity to the system and smother weeds... The primary function of cover crops is to produce biomass and provide continuous ground cover that protects the soil from erosion, conserves moisture, suppresses weeds, adds diversity, promotes soil biological activity and increases soil fertility through nutrient cycling... The main outcome of this project was to encourage growers to use cover crops in the rotation...

CSIRO complex systems team leader Dr Lindsay Bell heads the ground-breaking GRDC-funded Northern Farming Systems project exploring ways to boost whole-farm cropping productivity... The Northern Farming Systems Project involves one core trial site, six regional sites and computer-based modelling... The systems are comparing management strategies that influence: crop intensity (the number of crops sown per year) by altering soil water thresholds for planting crops; crop diversity by increasing the frequency of break crops and/or legume crops in the sequence; nutrient supply by altering crop nutrient budgets and adding organic amendments; and integrated practices such as cover crops and pasture rotations to restore or build soil quality...

New funding for the world's agricultural genebanks aims to strengthen their ability to manage both conflict and natural disasters... The seedbanks, managed under the CGIAR program for managing and sustaining crop collections, house the world's largest and most diverse collections of wheat, maize, rice, potato, banana, sorghum, forages, beans and many other food plants... "With climate change greatly intensifying demands on plant breeders to develop new heat, drought and flood-tolerant crops, it is important for the samples conserved in the CGIAR's genebanks to be readily accessible and in optimal condition," says slaug Marie Haga, incoming executive director of the Global Crop Diversity Trust.

Concerns are increasing that climate change is starting to challenge the production of global staples such as rice white the world's population continues to rise... The FAO cited the critical need for crop diversity as populations are soaring and climate change is challenging staples such as rice and maize... The Norwegian investment adds to contributions from Italy, the European Union, and the US. Treaty secretary Dr Shakeel Bhatti said treaty-supported projects are helping food growers use crop diversity to adapt to the effects of climate change...

Details of the family's production of 80 hectares of sandalwood as a crop diversification option are outlined in the latest edition of the Grains Research and Development Corporation (GRDC) magazine Ground Cover ... Aaron Edmonds, wife Hilda and parents Margaret and Charles are primarily grain growers, producing wheat, barley and canola, and are also developing a new miniature sheep breed - microsheep@"... Mr Edmonds said that although generating an income from sandalwood harvesting was at least another five years away, he expected timber yields of 10 tonnes per hectare and prices of at least $5000 per tonne...

Mr Young, who farms 1200 hectares in a 450- to 500-millimetre rainfall zone east of Kojonup, WA, and who is a member of the GRDC"s western panel, says the reality that cannot be shaken off is the impact of falling grain prices and weeds... Mr Young says the economics of grain growing in recent times is dampening a lot of people"s enthusiasm, especially after many WA growers again took substantial hits from frost. ".. Mr Young says the weed problem that so many now face is "perfectly predictable" in a farming system based on an annual wheat monoculture that gives weeds an annual opportunity to revive and flourish...

Sharon O'Keeffe, Grains Research and Development Corporation (GRDC) manager regional grower services - north says the new term "crop sequencing" describes a cropping program that is not dictated by the set order of crops that defined crop rotation... "Growers often select a crop based on price projections but GRDC-supported research over a long period of time shows the benefits and value of crop diversity, particularly cereals following nitrogen-fixing legumes," Ms O'Keeffe said... The concept ties neatly into the new GRDC focus on research themes including 'Profitable Farming Systems' that aims to help growers design a farm system with the flexibility to adapt and respond to changes; manage risk; integrate new practices; and ultimately generate more profit, Ms O'Keeffe said...
