Fall Turnover: A Physical Look at Lakes

In most of Nebraska, deep lakes will tend to stratify or form layers, especially during summer. This happens because the density of water changes as its temperature changes. During the summer, a temperature difference is established between the upper water and lower water in a lake. The upper layer of water, called the epilimnion, is warm.  This layer is about as deep as the sun can penetrate.  The deep layer of water, called the hypoliminion is made of cooler water.

Scheduling the Last Few Irrigations of the Season Deserves More of Your Management Time Than Earlier Irrigations

Scheduling the last few irrigations of the season deserves more of your management time than earlier irrigations because one must not only focus on keeping the crop wet enough to produce optimal yields, but also on using up enough of the stored soil water to lower the level to 40% of plant available water in the top four feet. This level will give about 2.4 inches of water storage room in sandy soils and about 5.5 inches in silt loam soils. Unfortunately, many irrigators leave the soil fairly wet with little to no storage room according to a recent study.

Biological benefits of manure application on agricultural soils

Soil quality has been traditionally described in terms of chemical and physical properties; however, soil organisms play an important role in soil health. Some studies suggest that using manure as soil amendment could result in increased microbial biomass, which results in higher soil bacteria, fungi and higher microbial activity. Soil microbial activity is crucial for nutrient cycling, aggregate stability, fertility, and other soil characteristics leading to better crop productivity.

Improving Soil Structure for Increased Infiltration and Water Holding Capacity

Plant roots grow in soil pore spaces. Pore spaces are also where oxygen is found. Just as plant roots cannot grow without water, they cannot grow without oxygen. Soil pore space is important to plant growth and efficient water use. Soils with good structure have adequate pore space making them well drained while still having good water and nutrient holding capacity. Ideal soils have 50 percent soil particles and 50 percent pore space. An important aspect of good soil structure is soil aggregation.

Naturally Occurring Elements in Groundwater Last in a Series - Uranium

There are naturally occurring elements and minerals within Nebraska geology, and with that, it is not uncommon to find them in Nebraska’s groundwater. The final installment of the Spotlight Series is Uranium. Uranium

Slow it Down, Soak it in: Conserving Rainwater with Downspout Disconnection

When it rains in July and August, we are almost always thankful for the moisture. And yet this valuable resource is often directed off of properties and out of town as quickly as possible via downspouts and storm drains. Stormwater runoff is rainwater that does not soak into the ground. It flows from rooftops, streets, parking lots, sidewalks, driveways, bare soil, sloped lawns, and other areas.

Backyard Biogas Production from Animal Manure: Process and Utilization

This article outlines the process of production and benefits of utilization of biogas from manure for small scale animal farmers, especially those in developing countries. Apart from the sanitary benefit of proper management of manure, this article highlights other benefits that can be derived from animal manure. Thus, encouraging these farmers to store manure from their animal farms for use, thereby changing waste to valuable resources.

Update on 2019 Tunnel Collapse and Canal Washout, Irrigation Water Outlook for 2021

Irrigation is in full swing for the North Platte Valley in the Panhandle of Nebraska.  Water deliveries by the four major irrigation districts (Pathfinder, Gering-Fort Laramie, Goshen and Farmers) are expected to be near normal. The districts hope to deliver water to growers through the first week in September. Link to full article

Protecting Groundwater by Managing Animal Manure Products

Groundwater is often the main source of drinking water for rural communities, especially in the Midwestern United States, so it is important to keep that water at levels that are safe to drink while minimizing environmental impacts. Although animal manure has many benefits to farmers, it can contaminate groundwater supply if not managed properly. This article discusses important considerations when storing and applying manure and includes requirements for testing of well water.

Watering New Trees and Shrubs

Many new trees and shrubs are planted in April, May and June.  By far, the two most important considerations are implementing the proper techniques for planting and watering.

Manure Application Options for Beef and Dairy Systems

When it comes to animal manure from feedlots being applied to the land in Nebraska, developing management practices that efficiently uses the nutrients from manure while being environmentally sustainable can be a complicated process. This article introduces some land application approaches for beef and dairy feedlot systems.

Dietary Strategies to Reduce Nitrogen and Phosphorus Excretion in Feedlot Cattle

Dietary nutrients, specifically nitrogen and phosphorus, are excreted in manure from feedlot cattle. Dietary strategies, including calculated protein supplementation and phase-feeding programs, can be implemented by cattle feeders to decrease nutrient excretion and improve nutritional efficiency of the animal.

Naturally Occurring Contaminants – Part 4 of a Series – Arsenic

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 will continue with Arsenic. Arsenic

Periods of Critical Water Needs in the Vegetable Garden

In the vegetable garden, an even supply of water throughout the growing season is directly related to quality and yield of vegetables harvested from the garden. Generally, vegetable demand for water is high during the first few weeks of growth following germination, right after transplanting, and during flowering and fruit development. However, with each vegetable crop there are particular developmental stages when having a good supply of water is critical.

Water Law 101: Part 5, Groundwater - Wells

Part 5 of a series about basic water law in the United States, predominately in the western part of the country, and how it affects this finite resource. Water law can be traced back to Roman times and also has roots in English common law. Across the United States, it varies from state to state, and from East to West. When conflicts arise, courts usually determine the outcome, unless there are state or federal laws or previous case studies to resolve the issue. Exceptions to the law can arise from differences in each state’s water laws.

Applying Manure Management Concepts On-Farm

This year’s Land Application Recertification sessions, called Applying Manure Management Concepts On-Farm, are scheduled to be in-person at many locations across the state in June, with one taking place in May in Lexington. Manure trainings earlier this year were held virtually, but we’re making progress, and that means we’re looking forward to seeing everyone in-person for the next manure event.
