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.

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.
Water Zones

Water Zones

Once good soils are in place, create water zones. Water zones are distinct sections of your property which contain plants with similar water needs. Group ornamentals into H-M-L zones in the landscape. Keep each distinct plant group by themselves – set watering minutes per zone accordingly.

Introduction to Watersheds

Introduction to Watersheds

Everyone lives in a watershed. A watershed is the land area that contributes water to a location, usually a stream, pond, lake or river. Everything that we do on the surface of our watershed impacts the water quality of our streams, wetlands, ponds, lakes and rivers. What happens in one locality affects other downstream areas.

Frequently Asked Questions

What is Algae? Algae are defined as simple rootless plants that grow in bodies of water relative to the amount of nutrients available. Blue-Green Algae or Cyanobacteria:

Methane (Anaerobic) Digesters

A methane digester system, commonly referred to as an AD (anaerobic digester), is a device that promotes the decomposition of manure or 'digestion' of the organics in manure to simple organics and gaseous biogas products.
Odor Management

Odor Management

Odor emission is of great concern to the general public. An odor management plan is required in the permit application for livestock operations with more than 1,000 animal units. Producers need to understand odor emission from animal housing, manure storage and handling, and land application and available management options.

Pesticide Leaching & Runoff Management

Runoff and/or leaching can occur when pesticides are carried off the application site into water such as rivers, lakes and streams, wells, storm sewers, or into groundwater. Runoff/leaching can occur when too much pesticide is applied or is spilled on the surface, too much rainwater or irrigation water occurs in a short period of time, or highly water soluble pesticides are used. To gain a better understanding of how, where and why water runs off and how to prevent pollution read the following UNL publications:

Watershed Planning & Management

Watershed planning and management comprise an approach to protecting water quality and quantity that focuses on the whole watershed. This approach is necessary due to the nature of polluted runoff, which in most watersheds is the biggest contributor to water pollution. Polluted runoff is a caused by a variety of land use activities including development, transportation and agriculture, and may originate anywhere in the watershed. Watershed planning and management involves a number of activities including:

Pond Management Tool

A pond is a delicate aquatic ecosystem where multiple interactions affect one another. Knowing the surface area and volume of a pond is critical information to making proper pond management decisions about chemical dose, evaporation/filling rates, fish stocking rates, etc. Inaccurate measurements of area or volume can lead to ineffective aquatic plant management via under dosing, or worse, overdosing. Overdosing can remove too much plant biomass causing oxygen depletion and can potentially lead to fish kills.

Design Tools for Small AFOs

This spreadsheet design tool is used to assist the Sprinkler Vegetative Treatment System  engineer in determining the flow rate, pipeline friction losses, elevation losses, pump capacity, and required horsepower for the pump station. This tool also evaluates the water flow characteristics in the towable sprinkler  system.  Here individual nozzle performance is evaluated along with tube friction loss and water velocity.
