Cornell Computational Agriculture Initiative


Funded by the USDA, the Cornell Computational Agricultural Initiative accelerated the solution of agricultural research problems using the latest advanced computing and consulting services. For example, CAC improved weather data accessibility in order to help farmers make better crop management decisions. Today, farmers use Adapt-N to improve nitrogen management for corn. In 2017, Adapt-N was acquired by Yara International USA who plans to make the tool available worldwide.
