Catalogue: GRDC Final Reports
Although biochar addition to soil did decrease inorganic N leaching, soil N mineralisation either decreased or did not change... The application of pyrolysed organic matter or biochar to soil can remediate decreased SOM and sequester C. The application of biochar to soil has also been shown to improve soil fertility and enhance yields of crops such as maize, wheat and peanuts... As biochar addition to soil can increase microbial community size and activity, previous research has hypothesised that this mechanism may be responsible for enhanced N mineralisation rates and contributes to the demonstrated improvements of N fertiliser use efficiency (up to 90%) in glasshouse-based agronomic research...

Not only do summer weeds rob growers of valuable soil moisture and nitrogen, recent research suggests it is also robbing growers of substantial profits through large yield losses... New South Wales Department of Primary Industries research and development agronomist Colin McMaster has led much of the research into the effects of summer weeds on plant available water and nitrogen in following crops and the yield benefit from controlling summer weeds... Temperature, moisture and organic carbon percentage are key drivers for nitrogen mineralisation a great opportunity for growers to build free nitrogen during the summer months when seasonal conditions allow...

, a simple computer program estimates water and nitrogen accumulation during fallows and complements more direct methods such as the push probe, soil cores and soil analysis... uses farm rainfall records for the current season to estimate the effectiveness of rain for future crop... Nitrogen mineralisation from the soil organic pool during the fallow period is also estimated based on soil moisture, temperature, soil type and years of cultivation...
