Mr Panigrahi has studied conditions inside steel on-farm grain silos under South Australian conditions to develop a modelling system that can accurately predict thermo-physical and biological phenomena occurring within the stored grain ecosystem, and model the impact of factors such as aeration, solar radiation and wind on the silo wall.
Aeration studies of both galvanised and white-painted steel silos were conducted with GRDC support at Balaklava, South Australia during the 2017-18 and 2018-19 seasons. The resulting data formed the benchmark for developing the model and predicting the number of required fan hours to cool and condition the stored grain.
Accurate modelling will help optimise the use of aeration in silos to give the greatest cost/benefit outcomes for growers under SA’s hot, dry conditions.

Developing a successful stored grain ecosystem model requires input and interaction by engineers and scientists specialising in the subject.
The American Society of Agricultural and Biological Engineers 2019 Conference (ASABE 2019) provided an ideal opportunity to engage with global experts.
The core objectives of the project were to:
In the field
ASABE AIM 2019 was held in Boston, USA from 7 to 20 July 2019. The meeting comprised events in nine major Technical Communities:
Sessions within these fields of research were progressed with both oral and poster presentations. There were also Young Professional Communities for graduate students considering their future careers.
Total attendance was 1,808 industry professionals from 48 US states and 36 countries.
While attending AIM 2019, Mr Panigrahi met engineers from the United States Deptartment of Agriculture (USDA) and professors from various universities with extensive experience in the stored grains research area – including:
He took part in three panel discussions on improving current on-farm grain storage technology and co-authored the paper Effect of Mediterranean climatic conditions during aeration and silo wall coating in on-farm grain storage in South Australia Panigrahi, S.S., Singh, C.B. & Fielke, J.M. (2019, July) published in 2019 ASABE Annual International Meeting (p.1), American Society of Agricultural and Biological Engineers.
Value for growers
Through interactions, discussions, presentations and developing contacts with leading agricultural engineers from around the world, Mr Panigrahi will be able to advance grain storage ecosystem modelling specifically for South Australian climatic conditions.
His computational work following ASABE AIM 2019 is being supported by SAGCO (USA119) and will help enable the ongoing improvement of on-farm grain silo storage practices in South Australia.
