While the majority of the data currently in ASRIS has come from government sources, this is not a policy restriction.
As a data repository, ASRIS has the benefit of being administered by CSIRO, which unlike most State agencies, does not have a regulatory function; hence, there may be greater community acceptance of direct lodgement of data into ASRIS, rather than via State databases.
If soil science (in particular soil carbon work) is to proceed across Australia in a manner that will achieve maximum value for investment and future use of data, researchers must ensure that minimum site description standards are met, sites are accurately located, and that data are lodged in State agency systems and/or ASRIS.

For the ASRIS project, the agricultural zone was defined as catchments designated by the State and Territory agencies as containing significant agricultural activity.
The objectives of this paper are to inform the research community of the existence of the ASRIS database and to describe its components.
ASRIS is a collation of the best available information that is needed to produce, for Australia's agricultural zone (1):
A new conversion was developed for ASRIS (Henderson and Bui 2002).
The new field pH data for topsoil is overlain on a raster image of the ASRIS Layer 1 pH dataset (www.
One notable region where the two datasets give clearly divergent results is in central-western Queensland (between 'g' and 'h') where the NGSA measurements indicate fairly acidic conditions (pH 4-7), compared to alkaline conditions according to ASRIS.
It is hoped that the recently released NGSA soil field pH dataset can be integrated into the ASRIS compilation to assist in providing a better and more widespread knowledge on this fundamental soil property across the country.
