Weekly Irrigation Newsletter: Using Soil Water Tension Sensors to Schedule Irrigation in Nebraska

Weekly Irrigation Newsletter: Using Soil Water Tension Sensors to Schedule Irrigation in Nebraska

In 2024, Nebraska Extension launched the Weekly Irrigation Newsletter to share timely insights on irrigation decisions, featuring three growers located in Nebraska. Due to the positive feedback, we are continuing the program in 2025. In each of their corn fields, we installed a set of three Watermark (Irrometer) sensors at 1-, 2-, and 3-foot soil depths to track soil moisture throughout the growing season. A rain gauge was also installed to monitor both rainfall and irrigation events. These instruments are connected to an IC-10 datalogger (Irrometer), which records data at one-hour intervals. With a telemetry system in place, the data is transmitted remotely, allowing for timely irrigation decisions.

Excess Nitrogen is Not Good and can Impact Plant Water Use and Water Quality

Excess Nitrogen is Not Good and can Impact Plant Water Use and Water Quality

Nitrogen is an essential plant nutrient. Like most things, too much of a good thing is not good. I recently visited with a gentleman who told me when he purchased a shade tree he was told to fertilize it once a week through the growing season. I’m also asked if trees need to be fertilized. The client is often asking because their lawn service is offering to fertilize their trees at the same time they fertilize the lawn.

The Shell Creek Watershed Improvement Group: A Nationally Recognized Success

Farmers, community leaders, researchers and extensionists met in March to recap successes of the Shell Creek Watershed Improvement Group (SCWIG). SCWIG has been active for 25-plus years to promote best management practices to improve water quality and reduce flood impacts. The group includes farmers and community leaders who worked with the Department of Environment and Environment (NDEE), Lower Platte North Natural Resources District, several local schools, and other groups and organizations, incrementally growing supporters and funding year over year.
Methods of Landscape Irrigation

Methods of Landscape Irrigation

Irrigation is important to all plants, especially as drought continues. We’ve been receiving rain across most of the state but are still in drought. Even when we aren’t in a drought, irrigation is necessary and very important to overall plant health. There are many methods of irrigation, and they all have pros and cons, but any type of irrigation is better than none.
Safety Matters: Cultivating a culture of safety

Safety Matters: Cultivating a culture of safety

Farming is among the most hazardous industries, but adopting a strong culture of safety can significantly reduce risks and protect workers. In this article, Jason Oliver of Cornell University discusses how farms can implement consistent safety training and empower all workers to take responsibility for safe practices by drawing inspiration from high-reliability organizations like U.S. aircraft carriers. By addressing one hazard at a time and combining multiple controls when necessary, agricultural operations can enhance both safety and productivity while showing workers that their well-being matters.

It’s Time for Private Well Maintenance

It’s Time for Private Well Maintenance

Mid-late spring or early summer is the prime time to conduct a private well maintenance check. Winter can be especially hard on outdoor systems; surfaces and landscaping that are subject to the elements. Getting in the habit of inspecting and maintaining your well system in the spring and the fall is a good habit to get into. It will help ensure everything operates efficiently and can potentially save you from shelling out money for costly repairs.

How much can irrigation and nitrogen management impact yields? In the 2024 TAPS contest, the difference was 68 bushels — find out why in a new webinar from UNL’s Center for Agricultural Profitability.
Groundwater regulation impacts on Nebraska land values

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%.

How much water do cattle need and what water problems should cattle producers watch for?

How much water do cattle need and what water problems should cattle producers watch for?

Water is a critical nutrient for cattle, especially during hot summer months. Lactating cows may require 20–24 gallons of water per day, while calves need 5–10 gallons. Poor water quality—caused by high nitrates, sulfates, or blue-green algae—can lead to serious health issues or even death. Producers should regularly test water sources and manage tanks and troughs to ensure clean, safe, and accessible water for all classes of cattle.
