Nebraska Continues To See Modest Groundwater Decline

March 15, 2018
Based on tests in 5,200 water wells across the state, Nebraska has seen a modest decline in groundwater levels in the last five years. A new university report tracks well levels in 1-year, 5-year, 10-year, and pre-irrigation increments to identify trends.

Impacts of Extreme Heat Stress and Increased Soil Temperature on Plant Growth and Development

June 21, 2016
Both corn and soybean are susceptible to extreme heat (and water) stress during early vegetative stages as well as later critical growth stages (pollination for corn and flowering for soybean). Extreme heat stress can reduce plant photosynthetic and transpiration efficiencies and negatively impact plant root development, which collectively can negatively impact yield. The author recommends that during an extended heat wave (air temperature equal to or greater than 90 F for 7-10 days), applying 0.25-0.40 inch of water can be very beneficial.
