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

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

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

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.

Naturally Occurring Elements in Groundwater - Part 3 of a Series - Fluoride

There are naturally occurring elements and minerals within Nebraska geology, and with that, it is not uncommon to find them in Nebraska’s groundwater. This month, the spotlight series continues with fluoride.

Water Optimizer Tool

The Water Optimizer tool evaluates single fields for several crop options. Irrigated crops include: corn, soybeans, sorghum, wheat, alfalfa, edible beans, sunflowers, and sugar beets. Dryland crops include: corn, soybeans, sorghum, sunflowers, alfalfa and wheat in continuous, summer fallow and eco-fallow rotations.

Example: Estimating Manure Phosphorus Application Rates

The Nebraska P-Index developed by the University of Nebraska (2006) will be used for analysis. The P Index risk value is the sum of the erosion and runoff components. The interpretation of risk and recommended manure application risk fall into one of four levels: low, medium, high, and very high.

Manure Spreader Calibration

As crops come out of the field, manure application equipment typically begins going in. While knowing the nutrient concentrations in your manure, the nutrient levels in the soil, and the nutrient needs of future crop needs are important, another critical component of the manure application process is using the right manure spreader setting, speed, and lane spacing during application. Combining all of these factors to optimize application efficiency is called calibrating the manure spreader.

National SepticSmart Week is September 17-21

National Septic Smart week is Sept. 17–21, 2018. The U.S. Environmental Protection Agency (EPA) uses a week in September each year to focus on improved awareness of proper operation and maintenance of septic systems across the U.S.  The wastewater of approximately 25 percent of the population of the U.S. is treated by on-site or individual wastewater systems. In Nebraska, that statistic holds consistent with approximately 25 percent of our state’s population served by onsite wastewater systems on farms, acreages, suburbs and even some small communities.

Operation & Maintenance

Now that you know how a lagoon works, here is what you need to do to operate and maintain your system for maximum efficiency and long life. Minimize your exposure to wastewater - it contains disease-causing bacteria and viruses. Wear waterproof gloves, wash hands or shower, and disinfect breaks in skin after exposure to wastewater.

Reduce Need for Irrigation by Maintaining Crop Residue and Reducing Soil Tillage

Leaving higher levels of crop residue and doing less tillage can increase the soil water balance by increasing the amount of water that infiltrates the soil from irrigation or precipitation, and decreasing the amount of water that runs off the soil surface. More residue and less tillage also reduce the rate of evaporation of water from the soil. Maintaining residue on the soil surface and doing less tillage can significantly reduce the amount of irrigation water needed to grow a crop.

Land Planning Standards

An important component in implementing effective best management practices for stormwater management is the regulatory context for land development. Land Planning Standards are changing, and there are many good examples that have been rewritten to provide a stronger framework for land development that integrates green stormwater management practices.

Groundwater Levels

Groundwater levels are an indication of how humans and climate have impacted the amount of water stored below ground, and the amount of groundwater that flows out of the ground to streams, rivers, springs, and lakes. Depletion of groundwater resources would have major social, economic, and ecological impacts in Nebraska and beyond.

How Does a Lagoon Work?

A traditional lagoon system is a two part system. A traditional system has plumbing from the house and a lagoon.
