Residue Management

The tilled plots in the foreground of this photo had considerable soil loss and runoff during intense spring rains. The tilled soil surface was susceptible to raindrop impact, causing erosion and surface crusting. The crop residue on the no-till plots in the background absorbed raindrop impact and allowed more water to infiltrate into the soil. With the improved soil structure, the crop is healthier in the no-till.

Controlling Emissions

Good stewardship calls upon livestock and poultry producers to limit emissions of air pollutants where feasible. Odor control practices and technologies may take several forms. Information on control strategies may focus upon the type of emissions controlled or the source of air emissions.

Rain Gardens

You can reduce water runoff from your yard by planting a rain garden. A rain garden is a small depression planted to flowers and ornamental grasses. It is designed to temporarily hold and soak in rain water from a roof, driveway or open area. A rain garden is not a pond or wetland. It is dry most of the time and holds water after a rain. Water collected in the rain garden slowly soaks into the soil and disappears in less than 48 hours.

Tillage Concepts

Tillage of the soil has been used to prepare a seedbed, kill weeds, incorporate nutrients, and manage crop residues. The goal of the tillage system has been to provide a proper environment for seed germination and root growth for crop production.

LB 677 and Its Impact on Nebraska Animal Feeding Operations

U.S. Environmental Protection Agency (EPA) rules that took effect April 14, 2003 defined the procedures for defining animal feeding operations (AFOs) as well as concentrated animal feeding operations (CAFOs). CAFOs are required to obtain a National Pollutant Discharge Elimination System (NPDES) permit from Nebraska Department of Environment Quality.

Landscape Management Practices

Aim downspouts towards planted areas or pervious hardscape and away from impervious paved areas. Collect rainwater from rooftops in rain barrels or cisterns for reuse in landscape irrigation. Amend soil with organic matter. Core aerate lawns to help avoid or reduce soil compaction, increase water infiltration, and promote healthy root systems. Follow University and label recommendations and calibrate spreaders when using fertilizers and pesticides.  Only use these products when needed. Read and follow label directions for all lawn chemicals.

Pesticide Drift Reduction & Prevention

Pesticide drift occurs when pesticides are transferred in air away from the intended application site into adjacent areas. Pesticides can move as spray droplets, vapor drift, or solid particle drift.

Frequently Asked Questions about Watersheds

What is a watershed? A watershed is an area of land that drains to a common waterway, such as a stream, lake, estuary, wetland, or, ultimately, the ocean. Do I live in a watershed? Yes, everyone lives in a watershed. How can I find out my watershed address? Go to the EPA web page Surf Your Watershed What are water quality protection practices or best management practices?

What is Toxic Blue-green Algae?

Author: Tadd M Barrow, formerly Water Quality Extension Educator, School of Natural Resources NOTE: The Volunteering Monitoring Program referred to on slide 11 below (Flash application) has been discontinued, and Tadd Barrow is no longer with the University. Private lake testing is at the discretion and expense of the owner. 

Am I Current with Inspections & Records?

Documentation is critical to demonstration of a CAFO's compliance with regulations and good environmental stewardship. Records are especially important if a farm experiences a spill. A farm's ability to demonstrate continued good management prior to a spill will be an important consideration in determining liability and potential penalties.

Stormwater

What is stormwater? It's water from rain or melting snow. Watch the video and learn about rain water runoff and why it can be a problem.

Integrated Pest Management

Integrated Pest Management, or IPM, is a long-standing, science-based, decision-making process that identifies and reduces risks from pests and pesticides. It coordinates the use of pest biology, environmental information and available technology to prevent unacceptable levels of pest damage by the most economical means, while posing the least possible risk to people, property, resources and the environment. IPM provides an effective strategy for managing pests in all areas from developed residential and public areas to crop and wild lands.

Agricultural Irrigation & Water Quality

Research has shown that concentrations of nitrate - nitrogen have accumulated in the groundwater beneath areas where irrigation is intense and where the soils are permeable allowing for leaching of nitrogen fertilizer. Leaching is most severe for surface irrigation systems used to irrigate sandy soils. The Platte River Valley and Eastern Sandhills have been most severely affected.

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.

Separate Turf and Ornamentals

Do you have trees growing right in the middle of your lawn? Do you swear under your breath every time you mow, having to trim around them and practice some fancy footwork trying to maneuver the mower around the trunk? If so, perhaps it's time to redesign your landscape, separating the grass and all of the other plants. If you are building a new home, or moving to one with little or no landscaping, you can avoid this maintenance nightmare by simply thinking of turf as a part of the landscape unto itself.

Weekly Irrigation Newsletter: Using Soil Water Tension to Schedule Irrigation in East-central Nebraska

In 2024, Nebraska Extension started a new collaboration with three growers located in east-central Nebraska. We installed a set of three watermark sensors at 1-, 2-, and 3-feet soil depth and the sensors were connected to datalogger (IC-10 model from Irrometer) to record and store hourly data at one-hour intervals. The data can also be accessed remotely for quick irrigation decision.
