The ANDB generated from MRWP and ADB produced from Barwon Water were transported to the two experimental sites.
The ANDB used in the experiment were from MRWP (stockpiled on-site for 1-3 months) and were categorised as C2/T3 (contaminant grade 2 and treatment grade 3).
The hypothesis tested was that the mineralisation rates currently adopted by EPA Victoria for the calculation of NLBAR are different from the actual mineralisation rates for ANDB and ADB on two sites in Victoria.
However, they also determined the fate of N supplied from ANDB and ADB applied to a clay loam soil in the subtropical climate of South East Queensland, in a forage sorghum production system.
For comparison, Table 6 summarises the results from several experiments conducted on ANDB and ADB under different climatic conditions, with different soil types, using different techniques for the estimation of the mineralisable organic N.
