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.

Troubleshooting

Problems sometimes occur. Lagoon depth may fall below 2-foot minimum due to leak in artificial liner, clogged inlet pipe, low flow rate into lagoon, holes in dike from plant roots or burrowing animals, not enough clay in natural soil liner or not compacted.

Irrigation Management Publications from Nebraska Extension

Harvesting Crop Residues, NebGuide G1846 Issues of crop residue harvest, including nutrient removal and effects on erosion, soil quality, water loss, and yield are discussed in this NebGuide.
Nutrient Management

Nutrient Management

Water quality is affected by nutrient management when chemicals, soil, and residue move off of agricultural land or below it. This section focuses on a number of production issues that when managed correctly minimize the potential for off-site consequences because excess of the nutrients is limited or eliminated.
Soil Erosion and Sediment Control

Soil Erosion and Sediment Control

Soil erosion and sediment loss from construction sites has been documented as a major source of water pollution. Bare soil exposed to a rain event can become quickly eroded, leading to sediment that moves into adjacent storm sewers or lakes and streams. 

What happens in the lagoon?

Evaporation reduces the liquid volume of wastewater, returning water vapor to the environment. Solids settle to bottom and form sludge. There is an aerobic zone at the top of the wastewater layer where air movement introduces oxygen and aerobic microorganisms convert waste to carbon dioxide, ammonia, and phosphates.

Soil Water

Irrigation scheduling needs to begin with a discussion on soil and soil water. This is the basis of irrigation scheduling. Coarse soils, such as sands and gravels, have relatively large pores. However the number of pores is small when compared to a finer textured soil. Fine soils, like clays or clay loams, have relatively small pores. Having many small pores means that a fine textured soil can hold more water than a coarse textured soil.

Green roofs help manage stormwater by capturing rainfall.

Aquifers of Nebraska

There are at least seven major aquifer systems in Nebraska. By far, the High Plains/Ogallala aquifer is the largest in terms of volume of water in storage and withdrawals for irrigation. Several secondary aquifers exist in areas outside of the High Plains aquifer, providing water for irrigation, municipal supplies, and domestic use in parts of far western and far eastern Nebraska.

Septic systems operation and maintenance overview

Pump tank regularly. Have a professional inspect and pump the tank. Conserve water and spread usage over a period of time. Manage solids. Keep hazardous materials out. Let the system work naturally. Avoid drainfield compaction. Avoid introducing excess water to the drainfield. Maintain structural integrity of the drainfield.
