"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...

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...

The factors are important in trying to understand the trends measured in this project... Grains Research Update - August 04 Wellington investigations to either confirm traditional research or provide an opportunity to develop scientifically sound methodologies to compare what is happening in a real world situation... I believe using less fertiliser is better, to encourage better micro organism activity, but that's my guess...

I strongly believe that with good management in the right environment, livestock can complement a cropping enterprise in a number of ways and vice versa... The Environment Conventional cropping systems in the Central USA have low levels of biological diversity and rely heavily on synthetic fertilisers and herbicides... An experiment run over 10 years by Texas Tech University USA, has shown that an integrated crop/forage/livestock system compared with a cotton monoculture has decreased nitrogen use by 40% and lowered irrigation water use by 25% whilst maintaining similar profitability between the two systems...

Strategic tillage puts the pressure back on weeds.. The planting technology combines the functionality of a harrow for breaking up soil clods, removing weeds and covering seed on tilled paddocks, with that of press wheels used to compact the soil over seed in furrows... Using the RFM Ag press harrows to plant Kyabra chickpeas and Kennedy wheat into tilled soil this winter grains season, Darren says they have also cut downtime spent on machinery at seeding...

Three top tips to stop crown rot: rotate crops, observe plants for browning at the base of tillers and test stubble and soil... Reducing the risk before planting Reducing inoculum levels is vital to managing crown rot... In the short term these practices can increase infection rates in the next Figure 6: Crown rot distribution cereal crop, as broken up in infected cereal stubble...

Unfortunately cultivation spreads infected residues, which may increase plant infection rates counteracting any benefits from increased residue breakdown...
