During the lawn fertilization season, use responsible practices to help keep nutrients out of streams, rivers ponds, and lakes. For those who live in town, it is important to know that most curbs and storm sewer systems drain directly into surface water. As rainwater flows over surfaces like pavement and bare soil, it collects materials such as soil, plant and animal waste and fertilizers, which contribute nutrients to surface waters.

Nitrogen (N) budgeting, where accounting principles are applied to measured quantities of individual N sources, is one tool for understanding how long-term fertilizer-N use and irrigation contributes to nitrogen leaching. Here, we explore this tool by going through commonly-used conversions and calculations for N supply and nitrate-N leaching to account for changes in aquifer nitrogen contamination.

Flood-soaked grain or hay is almost certain to be contaminated, making it unfit for use as food or feed.  This summary describes regulatory considerations and recommended actions for management of agricultural grains and forages deemed unusable for food or feed following flooding.

Many areas of Nebraska have experienced higher than normal precipitation events recently, with some areas receiving rainfall that far exceeded a 25-year, 24-hour storm event. This abnormally wet weather pattern has caused drainage and flooding issues in some parts of the state. The Nebraska Department of Environmental Quality and Nebraska Extension would like to remind producers and landowners to be vigilant in monitoring lagoon and runoff holding pond levels.

Five methods are approved for the routine disposal of livestock carcasses in Nebraska: composting, burial, incineration, rendering and land-filling. In an emergency situation – such as when livestock losses occur due to extreme weather or another non-disease related event – these five options still exist, but may not be suitable in all situations. The feasibility of carcass disposal via incineration, rendering or land-filling will depend on existing infrastructure or resources and, therefore, will not be discussed here. Acceptable processes for emergency composting and burial of livestock carcasses are described here.

Here in the dead of winter, a valuable service to hire to maintain a residential property is a snow removal company.  No more aching back, slipping and falling and shivering in the cold.  Of course all of that comes at a price, so you have to determine if it’s worth it.  As well, as their employees clean off the snow, there’s a chance that your mailbox or landscaping might be harmed, so that may be a factor in the decision.

If you are an owner or employee on a permitted animal feeding operation, you know very well that maintaining complete and accurate manure management records is necessary to comply with your nutrient management plan (NMP). While you may have enough land within your operation to utilize all manure nutrients produced, it is quite common for manure to be transported from a livestock operation where it was produced to a neighboring crop farm for land application.

The Nebraska Lakes Association (NLA) is an organization which brings lake owners, managers and experts together to address the issues private lake management. The mission of the (NLA) is to provide a forum for information and resources to educate members so their lake experience is safe, healthy and enjoyable.

The City of Auburn, population 3,000, is located in southeast Nebraska, near the Little Nemaha River, approximately seven miles upstream of its confluence with the Missouri River. The City receives its drinking water from a wellfield located east of the community within an alluvial aquifer along the Little Nemaha River. The wellfield consists of 11 vertical wells averaging 45 to 50 feet below the ground's surface, pumping up to 150 million gallons per year.

Iowa State University researchers concluded from a long-term field study that poultry manure, when applied at a rate to meet the crop nitrogen (N) requirements, can reduce nitrate loss and achieve equal or better yields in corn soybean production systems. While this research focused on nitrate (NO­3-N) loss by field-tile drains (typically placed 3 to 6 feet deep), similar trends would be anticipated in Nebraska for nitrate leaching below the crop root zone and the eventual impacts on surface and ground water quality.

Spring manure applications may provide environmental and crop production advantages compared to fall manure applications. These benefits include reduced nitrogen leaching, increased crop yields, and higher phosphorus and potassium nutrient soil storage.

When it rains, do you know where rainwater from your property goes? Does it spread out and soak into the lawn or landscape beds to recharge soil moisture and benefit plants; or does it run off into the street and down a storm drain where it often transports pollutants to surface water?

Land Application Training events are coming up in February. Several new hands-on activities will focus on using weather forecasts to minimize manure application odors, considering where to stockpile manure prior to land application, selecting the “best” routes for hauling manure to fields and defining who is responsible for manure under various scenarios.

With winter in full swing, it is a common practice to use deicers on our sidewalks and driveways to prevent falling on ice. With deicing agents, we need to be careful to not harm our plants when we use them and make good choices on what we use.

Cedar trees are spreading into grasslands and reducing forages that support cattle grazing. The Nebraska Forest Service is promoting management practices to keep the trees from spreading outside of their usual habitat and into grasslands and areas along the banks of rivers and streams (called ‘riparian forests’). So what do cedar trees have to do with manure? Since 2015, two resourceful farmers have generously given up a few acres of their fields for UNL researchers to test various applications of mulch alone or co-mingled with cattle or swine manure.

As we move into winter, store lawn and garden pesticides correctly and securely. Read and follow the label for safety and to help prevent accidental poisoning or spills that could contaminate storage areas or water resources.

As a part of the North American Manure Expo events, participants were invited to tour a family-operated dairy farm located in Hamlin County, SD to witness first-hand some of the improvements that have been added to their manure management system over the past few years. I was able to observe how, in trying economic times for the dairy industry, this family farm has modified their manure management system to get the most out of precious resources – water and nutrients.

Freezing temperatures are ending the growing season and its time to do yard and garden cleanup to help reduce overwintering diseases and insects; and to reduce the amount of plant debris washed into streams, lakes, and ponds where they contribute to water pollution.
