Crop Production

The production of crops is the heart of Nebraska's economy. Water is essential to all plant growth. Thus Nebraska's economy relies on a plentiful supply of water to produce crops – in both rainfed and irrigated environments. Several factors involved with producing crops interact with either water supply or water quality issues – or both.

Groundwater regulation impacts on Nebraska land values

With new regulations being implemented in Nebraska because of falling groundwater levels, you may be wondering how they will impact the value of agricultural lands in those regions. Ag economists from the University of Nebraska - Lincoln and Daugherty Water for Food Global Institute analyzed what has happened historically. Their findings: Land values were unaffected by groundwater allocations. Neither allocations or well moratoria had any significant effect on the value of land that had already been developed for irrigation. Well moratoria reduced the value of dryland acres by 9%.
