Nebraska Agricultural Water Management Network (NAWMN)

The Nebraska Agricultural Water Management Network (NAWMN) project is designed to enable technology implementation in production fields to enhance agricultural water and crop production efficiency. The Network brings together groweres, UNL Extension, NRDs, NRCS, and crop consultants, and other interested partners to work on adoption of water and energy conservation practices. The Network functions are based on scientific research conducted by Professor Suat Irmak ( in different locations for different cropping systems.
