What We Do

  • During the growing season we provide weather, soil and crop information (across scales) to support decision making  
  • Before/after the growing season we benchmark economic and environmental performance, and perform what-if scenario analyses to explain causes and design strategies for the future.

Why We Do It

  • To provide data to assist decision making for increased profitability and environmental sustainability. 
  • To improve the science behind predictive tools, and explore different approaches to accurately forecasting yields and aspects of cropping systems.

How We Do It

We combine the use of;

a) the Agricultural Production Systems sIMulator (APSIM) to simulate plant growth and soil water and N dynamics

b) actual, historical, and forecasted weather information 

c) frequent soil and crop measurements from fields in Iowa,

d) machine learning algorithms, advanced statistical and visualization tools to disseminate the information. Read more about

FACTS is an ongoing project developed to forecast and evaluate in real-time soil-crop dynamics at  specific ISU research fields (field scale) and at regional scale. Predictions will be frequently updated as new information becomes available. The project investigators and Iowa State University are not responsible for extrapolations made by individuals to other fields.
