Winter cereal rye planted as a cover crop has been shown effective in capturing nitrate before it leaches from the root zone. We conducted on-farm trials in central and southern Minnesota to determine if a rye cover crop would capture significant root-zone nitrate in the fall and spring but release it in time to maintain yield in the subsequent corn crop.

With a tip of the cap to National Groundwater Awareness Week, which was March 11-17, the landscape and gardening industry must do their part to prevent groundwater and surface water pollution on the properties we manage.

Boating season is once again upon us and it is time to remember to clean, drain and dry watercrafts, angling equipment and any other items that come in contact with a waterbody between uses.  Zebra mussels, an invasive small mussel species, can live out of water for up to 2 weeks in the summer time in the right conditions and cleaning, draining and drying watercrafts and equipment for at least 5 days before launching in a different waterbody is pertinent.  Currently there is no effective way to eliminate 100% of zebra mussels from a waterbody so prevention is key. 

Planting for Water Savings Spring will be here before we know it, which is very exciting for plant enthusiasts. We can get outside and do some cleanup once it starts to get warm. Don’t get too excited though, winter could still show up for a couple more months. One thing you can do now, though, is plan your garden. Choose Well-Adapted Plants

Spring will be here before we know it and that means enjoying the outdoors! Its time for kayaking, swimming and fishing. And, if you are a pond or lake owner, it's time to think about what kind of management strategies you will use for your pond or lake this year.

Land application of organic materials for soil management in Nebraska is important. The availability of applied organic N and the fertilizer N substitution values of applied organic materials is not well predicted. The uncertainty of applied organic N availability leads to over-application of fertilizer N resulting in low efficiency of applied N use. Research has been done to validate or adapt canopy sensor guided in-season N application practices for fields with manure or other organic material applied, and to improve the prediction of the fertilizer N substitution values for organic materials.

A new University of Nebraska-Lincoln led partnership is helping agricultural producers explore emerging technologies and identify ways to strengthen profitability without increasing risk.

The UNL CropWater App. A handy tool for irrigators to use in the field to aid in irrigation scheduling.

As we begin a new year and will soon be thinking about lawns and landscapes, here is a reminder to focus on water. A limited resource we can’t live without. A New Year’s landscape resolution can be to conserve and protect water resources.  Now is a good time to analyze past growing seasons. When the weather was dry, were there plants that needed more frequent irrigation to prevent them from wilting? Could these be replaced with drought tolerant plants?

A resource reality of cattle production is that only 10-30% of the nitrogen (N) that is consumed (i.e. fed protein) is utilized by animals for growth, reproduction, milk production, and maintenance needs. Unused N is excreted, primarily in urine. While livestock production is not the only source of N, producers should recognize that agriculture is clearly the dominant contributor of N to the environment on regional and national scales, and animal manure is a key source along with commercial fertilizer. In April of 2017, the DC Circuit Court of Appeals ruled that EPA would have to require animal feeding operations to report ammonia emissions. EPA expects to receive a court mandate on January 22, 2018, enforcing its ruling and opening livestock and poultry operations to consideration under CERCLA/EPCRA.

Soil health management refers to the preservation and improvement in soil physical, chemical, and biological properties to maximize the productive capacity of soil. Cover crops and reduced tillage are promoted for improving soil health; however, soil amendments such as application of livestock manure and municipal biosolids have received less attention as a soil health improvement practice. A literature review, funded by the North Central Region Water Network and the Soil Health Institute, was conducted to summarize and discuss results of studies reporting chemical, physical, and biological soil properties from application of livestock manure, animal by-products (i.e. compost), and municipal biosolids and to identify further research needs.

The workshops and online course are designed to help farmers increase the economic value of manure and to understand and implement the nutrient management planning requirements of Nebraska’s Department of Environmental Quality regulations. Topics covered include: updates on manure management regulations, value of manure as a fertilizer and soil amendment, biosecurity on livestock operations, and more. Anyone currently using manure or considering adding manure to their cropping system fertility program is encouraged to participate.

In Nebraska, extreme winter temperatures can come on quickly and hang around for extended periods.  Those extended periods of cold can be hard on things, but what impact do they have on your septic system? Can they affect your well and your water system? And what can you do to limit any impact?

It’s hard to think about our plants in the winter months. It is even harder to realize that they are still alive and sometimes need care in the winter months. Once plants go dormant for the year many people believe that they need nothing until spring, but that isn’t always the case, especially in years with low or no snow or rain throughout the winter months.
