mineralisation

Catalogue: GRDC Updates (North)
The project has supported the development of farming systems that incorporate forage (lab lab) and ley (butterfly pea) legumes into grain farming systems... Growing canola is like having a fallow period as far as VAM populations in the soil are concerned... Research in the area of AWM is looking at tactics that can be implemented during the summer...

Model your nitrogen to account for in-crop mineralisation.. Growers should use models to determine their nitrogen budget to take into account the complicated factor of in-crop nitrogen mineralisation, according to CSIRO Research Fellow Dr John Angus... The rate of mineralisation cannot be effectively measured in the field for two reasons - the crop is taking up nitrogen as soon as it mineralises, so it is challenging to measure the input of plant available nitrogen through mineralisation, and the process of sampling to take measurements disturbs the soil and stimulates microbes, which changes the result...

Understand the factors that affect mineralisation.. The rate of mineralisation varies with soil temperature, water content and, depending on the soil type, it can vary with the amount of organic matter and residues, and pH - mineralisation is slower in acidic soils... During the growing season, the amount of mineralisation is reasonably predictable and models are available that will estimate mineralisation over time periods ranging from days to years...

Specific management practices alter the abundance and activity of microbes capable of processing both organic and mineral-N... Once we better understand the soil biological and chemical factors governing N-transformations in our agricultural systems, we can determine how agronomic practices can be used to synchronise N supply, from both fertiliser and soil sources, with crop demand... A primary goal of this project was to develop and use molecular tools to detect these N-cycling communities in Australian agricultural systems...

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...
