  3. Decision Dashboard

  4. AgClimate View • Plot local temperature and precipitation variation as far back as 1980, • Track county crop yields and trends, and • Consider crop yields in the context of temperature, precipitation, and growing degree day data • Used in tandem with other decision resources, AgClimate View can help you find long-term correlations between climate trends and yields, while helping you put your recent crop experience into historical context.

  5. Start by Selecting a Location

  6. Historical Weather Data

  7. Combine the Data

  8. Corn Growing Degree Days • This tool puts current conditions into a 30-year historical perspective and offers trend projections through the end of the calendar year. GDD projections, combined with analysis of historical analog data, can help you make decisions about: • Climate Risks – Identify the likelihood of early and late frosts/freezes. • Activity Planning – Consider corn hybrid estimated physiological maturity requirements, along with GDD projections when making seed purchasing and other growing season decisions. • Marketing – Look at historical and projected GDD when considering forward pricing and crop insurance purchases.

  9. Pick Your Location

  10. GDD Graph

  11. Probable Fieldwork Days • This spreadsheet-based tool uses historical “Days Suitable for Fieldwork”, as computed by USDA, to determine the probability of completing in-field activities in a given time period. This tool explores: • Short-term Weather Risks – Quantifies historical risk of weather-related agricultural delays. • Activity Planning – Evaluates the potential to complete fieldwork with current equipment in a timely fashion.

  12. Probable Fieldwork Days

  13. List of Future Tools • In-season Nitrogen Application • A tool to evaluate the potential for in-season fertilizer application • Examines time needed for application • Incorporates yield benefit from application and/or penalty for non-application • Climate Patterns • A tool to show the monthly impacts from the El Niño Southern Oscillation (ENSO) and Arctic Oscillation (AO) by regions in a state. • Provides average monthly precipitation and temperature, along with deviations from normal by phase (El Niño, La Niña, etc.)
