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

Nebraska Irrigation Center Pivot
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

Biological Benefits of Manure Application
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

Compost

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.

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

downspout redirection into a flower garden

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

Fixed-Dome Type biogas plant (Vigeli et al, 2014)
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 water flows through Tunnel No. 1 on the Goshen/Gering-Fort Laramie supply canal in 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.
