As the 2025 irrigation season approaches, it is essential to prepare your irrigation system and use effective scheduling tools to ensure efficient water use. After planting and crop emergence, irrigating at the right time can increase yields and save energy, especially during expected dry conditions.
Center pivot systems are the most common in Nebraska. Check the pump connection, electrical source, and engine operation to avoid inefficiencies. Verify discharge and pressure using flow meters and pressure gauges.
Walk the pivot to inspect nozzles, leaks, and sprinkler uniformity. Replace faulty nozzles and repair leaks to maintain good water distribution. Also, check pivot tracks to prevent damage and confirm flow meter accuracy.
For drip irrigation, inspect the field for leaks caused by animals or damage. Clean or replace flow meters if needed, and make sure filters are clean to avoid emitter clogging. Open manifold inlets fully to maintain pressure and check water quality to prevent emitter blockage.
Furrow irrigation requires open furrows with a gentle slope for smooth water flow. Ensure the drainage canal is clear and furrows are wide and deep enough for uniform water distribution. Proper drainage at the field end prevents waterlogging.
Using irrigation scheduling tools is crucial. These tools monitor soil moisture and help decide when to irrigate. Select easy-to-use, reliable technology that integrates with your farming operations. A strong internet connection is important for real-time data from soil sensors. Install sensors in healthy crop areas for accurate results.
Before the first irrigation, measure soil moisture in the top 12 inches. Avoid irrigating too early, which wastes water and energy and may cause nutrient loss. Typically, irrigation starts in late May or early June but adjusts based on soil moisture and weather.
In summary, check your irrigation system and invest in good scheduling tools. Use soil moisture data to avoid unnecessary watering and energy use during the dry 2025 season. This approach improves water use efficiency and helps achieve better crop yields.
