Queensland University of Technology's Professor Peter Grace discusses strategies to help avoid nitrogen losses at a recent GRDC Grains Research Update... The loss is caused by chemical reactions on the surface of the soil, and only occurs in alkaline soils when ammonium-based fertiliser is broadcast and there is no rain to wash it into the soil... Rain is required to wash the fertiliser deeper into the soil profile, but not too much that it could cause denitrification or leaching...

CliMate displays data such as stored soil water and nitrogen... CliMate estimates stored soil moisture based on individual paddock data, such as the length of the fallow period, the amount of soil organic matter, stubble load, soil type and rainfall received during the fallow period... Research undertaken over several years by NSW DPI staff such as Col McMaster and Barry Haskins (now a private researcher/consultant) noted that delayed or missed fallow weed control opportunities quickly led to loss of stored soil moisture, as well as loss of more than 40kg/ha of available soil nitrogen...

Mallee grower Allen Buckley has lifted the health of soils on his Waikerie, South Australia, farm... Growers: Allen and Jenny Buckley Location: Waikerie, South Australia Area: 5000 hectares Crops: wheat, cover crops Livestock: 1000 Merino ewes, half joined to Merino rams and half to cross-bred rams Soils: predominantly sandy Average annual rainfall: 250 millimetres (160mm growing season).. Allen is also experimenting with cover crops - another unusual sight in the Mallee - after seeing the results of CSIRO and South Australian Research and Development Institute trials on his farm and visiting growers in the US who sow a mixed cover crop rather than a monoculture...

If opening rains arrive early in the season, it may be advisable to sow the crop seven to 10 days after these rains - as results show that microbial activity remains high at this time, helping in suppression of the disease... Results of our experiments conducted during this project will help in understanding the behaviour of R. solani AG-8 under different soil environments and its interaction with rate of root growth and microbial activity in the development of disease... Our results will also help in the prediction of disease in a season on basis of timing and amount of opening rains...

Allen's life quest to nurture living souls.. Allen was one of the first Mallee growers to adopt no-till farming more than 20 years ago; back in an era when the region was notorious for losing millions of tonnes of topsoil to wind erosion... Over the years, the 5000-hectare mixed-farming enterprise Allen and his wife Jenny operate has become an example of how no-till farming can improve soil productivity, increase disease suppression and capture moisture in a low-rainfall environment to increase average yields...
