G98-1777 Windbreak Renovation, James R. Brandle, Jon Wilson, Craig Stange, Mike Kuhns

University of Nebraska-Lincoln Extension: Historical Materials

Windbreaks are an integral part of many farms and ranches and provide critical protection for farmsteads, livestock and crops. Unfortunately, many windbreaks planted in the 1930s and 1940s are losing their effectiveness due to age, poor health or neglect. In some cases, the windbreak no longer has the necessary density to provide winter protection. In other cases, overcrowding may have reduced the health and vigor of the windbreak, or the windbreak may have been invaded by aggressive sod-forming grasses such as smooth brome, reducing tree growth. Whatever the reason, many older windbreaks need renovation.

Ec94-132 Freeze Injury To Nebraska Wheat, Robert N. Klein, Drew J. Lyon, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska’s adverse weather conditions affect winter wheat during much of its growth. The newer varieties of wheat have increased winter hardiness, and better management practices have reduced winter injury of winter wheat, yet low temperature injury during winter and spring can be destructive. Wheat has little resistance to low temperatures after it begins growing in the spring; therefore, injury from freezes at this time can occur in any part of the state. This publication describes temperature conditions that cause winter injury, symptoms of injury at different spring growth stages, and management practices to use when wheat is injured.

G87-836 Coldframes And Hotbeds, Dale T. Lindgren

University of Nebraska-Lincoln Extension: Historical Materials

Coldframes and hotbeds can help the home gardener in many ways. This NebGuide explains uses, construction, and management.

Hotbeds and coldframes are mini-greenhouses in that both use solar energy and sunlight. Coldframes and hotbeds can help the home gardener start, grow and maintain plant material and the commercial grower propagate and display plant material.

The main difference between hotbeds and coldframes is that hotbeds have a supplemental heat source. This supplemental heat source may be organic, such as manure, or non-organic, such as an electric heating cable. Construction can be simple and inexpensive or quite sophisticated. Hotbed/coldframe size can vary.
