This innovative tool integrates corn development stages with weather and climate data for location-specific decision support tailored specifically to agricultural production.

Determine the feasibility and profitability of using post-planting nitrogen application for corn production. This product combines historical data on crop growth and fieldwork conditions with economic considerations to determine best/worst/average scenarios of successfully completing nitrogen applications within a user-specified time period. Now available for 12 states in the north central US.

The U2U Irrigation Investment DST lets you explore the potential profitability of installing irrigation equipment at user-selected locations across the Corn Belt. Discover how many years from 1980-2005 irrigation would have been profitable, calculate the net present value of investment, and compare dryland and irrigated corn and soybean yields under different rainfall conditions.

Disclaimer on the Use of Data and Products from the HPRCC


Climate products and tools are developed by the HPRCC and its partner Regional Climate Centers to provide users with a means to routinely access recent weather and climate data. While applied research has demonstrated that the use of such data in decision making can reduce risk and lower a user's cost, it must be pointed out that near-real-time data are preliminary in nature and sometimes contain errors. Although care is taken to remove known errors, it is possible that some data will change after receipt of written records and final quality control steps. Users are therefore forewarned to consider any negative impact that errant data might have on their business and use preliminary data and information at their own risk.
