Chemical forms of organic P have been partially characterised in these soils... A future project using the data generated from UA00062 and using outputs from other GRDC research projects on C and N decomposition could be aimed at the construction of a combined C:N:P organic matter mineralisation model relevant to farming systems on southern Australian soils that will underpin the development of a P fertiliser decision tool... Biochemical composition (e.g. lignin content, total and water soluble P, C and N) for a number of different plant residues were measured and related to release of plant-available P as well as changes in organic P (labile, microbial and stable) pools...

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...
