Pivot irrigation system — When irrigating fields early due to drought, the most reliable method to know when and how much to irrigate is to monitor soil moisture at multiple depths.

Early Season Irrigation During Drought

June 7, 2023

For producers who are irrigating early this year due to drought, it's critical to monitor soil moisture to balance crop needs with the risk of losing nitrogen and other valuable crop inputs, while also avoiding the expense of over-irrigating.

Irrigation system in corn — Producers looking to take advantage of nitrate-nitrogen in groundwater to reduce nitrogen applications this growing season may want to test their wells to determine current levels. Information on testing requirements is available at all local NRD offices.
