Aquatic Plant Control

Aquatic Plant Control

Managing aquatic plants in a pond or lake can be like walking a tight rope, especially in shallow lakes.  When lakes receive excess nutrients, primarily phosphorus in Nebraska, the result can be a dense growth of aquatic plants.  But when too many aquatic plants are removed, water clarity and algae problems may follow.
Utilization of Woody Biomass as an Agronomic Land Treatment and Conservation Practice in the Middle Niobrara Natural Resources District Long Pine Creek Watershed

Utilization of Woody Biomass as an Agronomic Land Treatment and Conservation Practice in the Middle Niobrara Natural Resources District Long Pine Creek Watershed

A value-added market for woody biomass (wood chips) generated during management of Eastern Red Cedar and native trees in riparian forests and rangeland is critical to offset the cost to landowners of managing forested areas for fire prevention, invasive plant species control, improving wildlife habitat and ecological preservation. Utilization of wood chips alone and co-mingled with livestock manure or nitrogen fertilizer is being investigated (since 2015) as a land treatment practice on local landowner crop fields with research focused on evaluating impacts on soil moisture holding capacity, temperature, biology, & other properties that impact crop productivity.

Value of Using Sensors to Manage Irrigation and Tips for Proper Installation

Use ET Gages and soil moisture sensors to help manage your irrigation this season.
Abandoned swine lagoons and earthen storage basins may contain valuable nutrients

Abandoned swine lagoons and earthen storage basins may contain valuable nutrients

When a swine lagoon is abandoned, the owner has the choice of decommissioning the lagoon or maintaining the integrity of the lagoon. Decommissioning means dewatering the lagoon and land applying the sludge at the bottom. One cannot just fill in the hole. The process of removing the water and the sludge is time consuming and takes resources and planning to complete properly. One aspect of the process does have some cost recovery and that is utilizing the sludge in a beneficial way.
Is Your Irrigation System Ready For the Season?

Is Your Irrigation System Ready For the Season?

Simple checks you can preform on your center pivots to make sure they are ready for the irrigation season.

Nebraska Weather and Your Water Supply

Nebraska weather is anything but stable and predictable. February reiterated that point to us as we saw record numbers of days with highs in the 70s, our first thunder of 2017 followed by up to two feet of snow in some parts of the state. Severe thunderstorms and tornadoes are most common during May, June and July but they can occur at any time and are increasingly common as warm air patterns begin to dominate during the spring months.
Finding Win/Win Opportunities for Manure

Finding Win/Win Opportunities for Manure

This article is Part 1 of a two-part discussion on the value of manure. Part 2 focuses on soil quality benefits provided by manure and appeared in the March 6, 2017 CropWatch.

Pesticide Safety

Pesticides are a commonly used method of managing pests in our landscapes. However, pesticides are poisons, so they need to be handled carefully. With spring here and summer coming right around the corner, it is a good time to reinforce those safety precautions to everyone who might be using pesticides. 
2017 Sandpit Lake Management Workshops

2017 Sandpit Lake Management Workshops

Nebraska Extension, the Nebraska Department of Environmental Quality, and Game and Parks again have partnered to offer a series of pond and lake management introductory workshops.  These workshops are free and open to everyone who makes decisions for and about lakes and ponds or anyone who wants to learn more about protecting them.  If you’ve ever had an algae bloom, fish kill, murky water, or just want to know what’s going on in the lake, this workshop is for you.  All 2017 workshops are focused on sandpit lakes.
2017 Spring Stormwater Symposium

2017 Spring Stormwater Symposium

The 2017 Spring Stormwater Symposium brought together professionals from both public and private sectors to learn from local, regional and national experts. The symposium will focused on examples of stormwater program funding and management, and took an in-depth look into the life cycle of a successful stormwater management project.

CropWater App for Irrigation Management

CropWater App for Irrigation Management

The CropWater App is one of the earliest irrigation management apps developed many years ago and its functions are based on the research conducted by Dr. Suat Irmak. It is a product of our efforts in the NAWMN to enhance technology implementation in agricultural production.

Cover Crops

Crops including grasses, legumes or forbs used for seasonal cover and other conservation purposes. SARE Publications 2007, Managing Cover Crops Profitably, 3rd Edition. Beltsville, MD: Sustainable Agriculture Network, 244 pgs. $19 for book; PDF version available.

Economics & Costs

The University of Nebraska's Bureau of Business Research conducted a study in 2003 to determine the impact of irrigated agriculture on Nebraska 's economy. The net total economic impact was computed by comparing impacts with irrigation to what would have resulted without irrigation. The research examined actual 2003 impacts and what would have occurred if average precipitation had occurred. For normal precipitation the total impact of irrigation would have been just over $3.6 billion per year. Since 2003 was a drought year, the actual economic impact was more than $4.5 billion.

Estimating Manure P App Rates

Manure phosphorus application rates should be estimated. These estimates should be based upon the most recently available information for manure nutrient concentration (manure sample) and the estimate of crop nutrient needs. Since this information is not typically available at the time of a permit application, estimating manure phosphorus application rates as part of a permit is, at best, an educated guess made without essential information.

Stormwater Regulations

The National Pollution Discharge Elimination System (NPDES), established through the Federal Water Pollution Control Act (FWPCA) Amendments of 1972 (later amended and known collectively as the Clean Water Act), regulates water quality by requiring a permit for point source pollution discharges to waters of the United States.

Other Systems

Some areas in Nebraska are not appropriate for a conventional septic tank/drainfield system or a residential lagoon. We consider these environmentally vulnerable areas.

Manure Nutrient Management

Manure Nutrient Management

Water quality protection is primary to good stewardship of our environment; and fundamental to good stewardship is application of manure and fertilizer nutrients at field-specific agronomic rates with careful consideration of timing and location. Following nutrient management principles is a requirement for compliance with Nebraska and U.S. environmental regulations for all permitted animal feeding operations.
Conservation Subdivision Design

Conservation Subdivision Design

Conservation subdivision design (CSD) entails a broad range of design principles and parameters that collectively enhance environmental quality, the aesthetics and quality-of-life of residents in the subdivision, and the profitability of the development for the developer.
