soil microbial biomass

Catalogue: GRDC Updates
" Date: 08.10.2009 USING ROTATION CROPS TO IMPROVE SOIL QUALITY.. Soil structural differences are measured with a cone penetrometer which determines the force needed to push a metal probe slowly into the soil to 600 mm depth... We measured the microbial properties using surface soil samples (0-10 cm) from the crop rotation experiment...

Catalogue: GRDC Final Reports
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...
