A Little Bit about U2U
Our goal is to help producers make better long-term plans on
what, when and where to plant, and also how to manage crops
for maximum yields and minimum environmental damage.

Decision Support Tools
Ag Climate View
– provides easy access to historical climate and crop data
Growing Degree Days (GDD) Tool
– tracks real-time GDD accumulations and outlines climate
risks for corn development

Ag Climate 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, Ag
Climate View can help you find long-term correlations
between climate trends and yields, while helping you
put your recent crop experience into historical context.

Growing Degree Days Tool
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.
