The key to knowing the correct setting for a chemigation pump is to first determine how many acres per hour the pivot will cover at the desired irrigation application depth or rate.
The amount and timing of irrigation applied in recent years may have very little to do with what's needed this year. Review the factors before making a decision.
In 2024, Nebraska Extension started a new collaboration with three growers located in east-central Nebraska. We installed a set of three watermark sensors at 1-, 2-, and 3-feet soil depth and the sensors were connected to datalogger (IC-10 model from Irrometer) to record and store hourly data at one-hour intervals. The data can also be accessed remotely for quick irrigation decision.
Nebraska growers share Week 2 results of their irrigation management decisions based on soil moisture sensor data, as part of a new collaboration with extension educators.
