To ascertain the major differences in soil types in the region, and provide more accurate and timely information on a broad, generic scale that would have better relevance for growers in the region.
The model was very accurate at the actual soil site location. Inaccuracies can be due to a number of reasons - namely weed burden at the site, frost, variations of soil type across the paddock and variations of rainfall received in the paddock versus the recording location. Furthermore, if the soil classification is slightly different in the model than is actually the soil physical properties, this could cause deviation as well. Lastly, as crop phenology can vary from cultivar to cultivar, this can cause discrepancy too.

Soil cores were taken by Ecoprobe on 21 and 22 April 2012, to establish the soil physical and chemical properties. 5 cores were taken at each site, with one core being left out for observation purposes during the season. This information is then fed into the Yield Prophet computer model in the online site. |
