30 October 2018 - Please participate in the Minnesota Geospatial Priorities Survey before Nov 6
The MN Geospatial Advisory Council (GAC) is defining statewide geospatial priorities for 2019, and needs your input. The GAC is asking members of the Minnesota geospatial professional community to respond to a short survey about geospatial needs. The survey will be open through November 6.
Why does the GAC create priorities?
- To create a voice for the Minnesota geospatial community
- To direct work plans of the GAC and its committees
- To recommend priorities to MnGeo
- To allow other organizations to compare priorities and align efforts
- To inform outreach and policy related efforts
- Having clear direction helps motivate people to participate
There’s some great questions on spatial data overall, and some crucial questions on LiDAR. This support is needed for extremely high resolution and high quality LiDAR data on the state's next collection campaign, which would be beneficial for precision agriculture research and tenchnology transfer moving forward.

Advances in Crop Simulation Modeling - From Basic Research to Practical Applications
Abstract - During the past decades, computer models that predict crop growth, development, and yield have become an integral part of agricultural research, outreach, and education. These simulation models have been implemented for many different spatial and temporal applications, ranging from gene-based crop modeling to climate change impact assessment and adaptation studies for policay recommendations. In this seminar, Dr. Hoogenboom will present a general overview of crop modeling and provide some specific applications of the international modeling platform DSSAT (Decision Support System for Agrotechnology Transfer).
Sustainable Cropping Systems Seminar in Waseca, MN
Tuesday, September 18 | 10:00 AM | Conference room, SROC (Waseca)
Crop Modeling as a Tool for Research and Extension
Abstract - Crop simulation models are a relatively new discipline in the field of agriculture. In general, crop simulation models can be used to predict the dynamic interaction between Genotype, Environment, and Management. When interfaced with decision support systems, crop models can also be linked to the economic components of the agricultural production system. Following evaluation with local experimental data, the crop models can be used to evaluate short- and long-term management practices for local environmental conditions. In this seminar, Dr. Hoogenboom will present a general overview of crop modeling and specific applications of the international modeling platform DSSAT (Decision Support System for Agrotechnology Transfer).
Dr. Gerrit Hoogenboom | Preeminent Scholar, Institute for Sustainable Food Systems, University of Florida Professor, Agricultural and Biological Engineering, University of Florida
About the speaker - Dr. Gerrit Hoogenboom is a Preeminent Scholar in the Institute for Sustainable Food Systems, and Professor of Agricultural and Biological Engineering at the University of Florida, USA. Prior to joining the University of Florida, he was the Director of the AgWeatherNet Program and Professor of Agrometeorology at Washington State University. He has over 25 years of experience in the development of crop simulation models and decision support systems. Applications range from freeze forecasting to climate variability and climate change, water resources management, biofuels, economic and environmental sustainability, and food security. He currently coordinates the development of DSSAT, a crop modeling system that is being used world-wide by many scientists and others interested in systems analysis and decision support. He received his Ph.D. from Auburn University, M.S. in Theoretical Production Ecology and M.S. and B.S. in Horticulture from Wageningen University, the Netherlands.
About the seminars – The seminars are a joint effort of the Cropping Systems research groups at the Southwest and Southern Research and Outreach Centers led by Axel Garcia y Garcia and Gregg Johnson, respectively. Our goal is to generate sound debate on current and future cropping systems that increase profitability and resiliency, improve resource use efficiency, and contribute to environmental quality.

27 February 2018 - U of M licenses technology to monitor crop nitrogen status to ag-tech firm Sentera
Sentera, a Minneapolis-based supplier of technology solutions to the agriculture industry, has signed an agreement to bring University of Minnesota-developed corn nitrogen deficiency technology to the market. The technology allows growers to more precisely match applied nitrogen fertilizer to the optimal needs of the crop. Minimizing over-application of nutrients saves money; reduces the risk of fertilizer runoff into lakes, streams and rivers; and preserves crop yield. Under an exclusive agreement, Sentera will integrate the capability into their FieldAgent™ Platform, a software using drone technology to advance precision agriculture. The company will begin field trials with several of its largest customers this year, with commercial rollout planned for 2019. Read more...
