G74-174 Fertilizer Suggestions For Corn (Revised July 1995), Gary W. Hergert, Charles A. Shapiro, Richard B. Ferguson

University of Nebraska-Lincoln Extension: Historical Materials

Fertilizer nutrient requirements for corn are based on expected yield and nutrient levels in the soil. Nitrogen is the nutrient most often required for growing corn. Nearly all corn in Nebraska will need some nitrogen fertilizer unless there is substantial nitrogen in the soil from sources. Phorphorus is the second nutrient most likely to be needed, and needs are best determined with a reliable soil test. Potassium, sulfur, zinc, and iron fertilizer may be needed for growing corn on certain soils. Crop needs for calcium, magnesium, boron, chlorine, copper, manganese, and molybdenum are adequately supplied by Nebraska soils.

G74-154 Mosquito Control Guide (Revised 1974), John B. Campbell, David L. Keith, W. Kramer

University of Nebraska-Lincoln Extension: Historical Materials

Mosquitoes are insects belonging to the order Diptera. Although there are some 50 species of mosquitoes in Nebraska, fewer than a dozen are important.

G74-131 No-Till Corn In Alfalfa Sod, Alex R. Martin, Russell S. Moomaw

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska produces about 1,740,000 acres of alfalfa annually. Corn or grain sorghum usually follows alfalfa in the crop rotation. The moldboard plow or chisel plow are commonly used to break up alfalfa sod for corn planting. The plow is a high consumer of energy, requiring about 2.25 gallons of diesel fuel per acre.

Research conducted in Nebraska has been used to develop a system in which the alfalfa is killed with herbicides and corn is planted directly into the sod without tillage. Plowing is eliminated and energy requirements can be reduced to about 1/4 that used in the conventional plow …

G74-166 Creep Feeding Beef Calves, Richard J. Rasby, Ivan G. Rush, James A. Gosey

University of Nebraska-Lincoln Extension: Historical Materials

Effects of creep feeding calves are covered here. Gross income of the cow/calf enterprise is partially dependent on weaning weight of the calves. Three possible non-genetic ways of increasing calf weaning weight are to increase milk production of the dam, increase forage consumption of the calf, or provide supplemental feed to the calf to increase nutrient intake. Management practices exist to increase standing forage quality, but management of that grass for the calf only is difficult. Likewise, increasing milk production of the dam requires greater feed inputs and possibly supplemental feed. Creep feeding studies consistently have shown an increase in …

G74-100 Feeding High Moisture Corn, Terry L. Mader, Paul Q. Guyer, Rick Stock

University of Nebraska-Lincoln Extension: Historical Materials

In recent years the use of high moisture grain has become more popular due to the increased costs of handling and dry feed grains. For cattle feeders in particular, storing grains as high moisture is one practice that can improve their competitive position and reduce costs. Using high moisture grains allows greater opportunity to design a system that will minimize harvest, storage and feed processing costs.

Grains such as sorghum and wheat have been stored as high moisture, but corn is the principal high moisture grain stored. High moisture corn can be processed and stored as whole shelled corn, ground …

G74-149 Bloat Prevention And Treatment, Rick Stock, Richard J. Rasby, Duane Rice

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the types of bloat which may occur in cattle and methods to prevent and treat bloat.

Bloat is a form of indigestion marked by an excessive accumulation of gas in the rumen. Immediately after cattle consume a meal, the digestive process creates gases in the rumen. Most of the gases are eliminated by eructation (belching). Gases that are trapped and not eructated may form a foam or froth in the rumen which further prevents their elimination. Froth formation can be caused by many factors resulting from interactions between the animal, rumen microorganisms, and differences in plant biochemistry.

G74-136 Grain Sorghum Processing For Beef Cattle, Rick Stock, Terry L. Mader

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the feeding value of grain sorghum relative to corn and various grain processing methods for grain sorghum.

It has been widely recognized that grain sorghum (milo) must be processed to be efficiently used by finishing cattle. Grain sorghum shows more improved utilization from processing than corn, wheat and barley. Dry ground or rolled grain sorghum has a relative feeding value of 85% to 95% (avg 90%) of dry rolled corn. Processing grain sorghum by more sophisticated methods (early harvesting, steam-flaking, etc.) greatly enhances its feeding value.

Chemical composition suggests that there should be less difference in the …

G74-170 Nitrates In Livestock Feeding, Richard J. Rasby, Rick Stock, Bruce Anderson, Norman R. Schneider

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes symptoms, causes, prevention and treatment of nitrate poisoning in livestock.

Nitrate poisoning in cattle occurred long before the use of nitrogen fertilizers. In the late 1800s there were reports of cornstalk poisoning in Nebraska, and nitrate poisoning from oat hay in North and South Dakota and from weeds in the high-organic matter soils in Florida and Wisconsin.

Nitrate concentrations in feeds for livestock depends more on plant species and environmental conditions prior to harvest than on the amount of available nitrogen in the soil.

G74-99 Estimating Corn And Sorghum Silage Value, Paul Q. Guyer, Douglas D. Duey

University of Nebraska-Lincoln Extension: Historical Materials

Arriving at fair and equitable prices for silage requires judgment and attention to detail.

Arriving at fair and equitable prices for silage requires judgment and attention to detail. The amount of grain and moisture contained have major influences on its feed value, and can be used to increase the accuracy of silage pricing.

Grain usually comprises 50 to 55 percent of the dry matter and produces 65 to 70 percent of the protein and energy value in corn varieties selected for grain production. On the other hand, silage varieties are more variable, with some having considerably lower grain yields and …

G73-57 Hot Weather Livestock Stress, Allen C. Wellman

University of Nebraska-Lincoln Extension: Historical Materials

During periods of high temperatures and humidity, livestock losses can occur from "Hot Weather Stress." How weather stress is particularly hazardous to closely confined livestock (those in feedlots, sorting and holding pens, trucks and rail cars). High relative humidity when the temperature is at 80 degrees or higher adds to the likelihood of profit-stealing losses if necessary precautions are not taken.

Nebraska livestock producers can make their livestock handling and marketing plans flexible enough or take necessary precautions to reduce or eliminate livestock hot weather stress by following this Livestock Weather Hazard Guide.

G73-62 Webworm Control In Sugarbeets (Revised March 1979), Arthur F. Hagen

University of Nebraska-Lincoln Extension: Historical Materials

The sugarbeet webworm and the alfalfa webworm attack sugarbeets. Frequent outbreaks have been reported in sugarbeets from both species, so they are now generally listed only as "webworms." Their life history, damage and control are similar and are discussed in this publication.

G73-71 Lettuce (Revised April 1990), R.E. Neild, Roger D. Uhlinger

University of Nebraska-Lincoln Extension: Historical Materials

Successfully growing and harvesting lettuce is the focus of this NebGuide.

Lettuce is an increasingly popular vegetable in the United States. Because it is a basic ingredient in salads, lettuce is eaten more frequently than any other vegetable. Lettuce can be served alone with a variety of dressings or mixed with other fresh vegetables.

Its fresh color and crisp texture serve well as a garnish, and its leaves may be stuffed with fruit, cheese, seafood, poultry, ham, or egg salads. Although usually consumed fresh, leaf lettuce and chopped green onions "wilted" with warm vegetable oil and vinegar make a pleasing, …

G73-15 Handling Feed Moisture In Ration Formulation And Inventory Control (Revised December 1983), Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

Nutritional quality control begins with knowing and adjusting for variation in the moisture content of feed ingredients. Moisture variations in feeds are almost always of more importance than variations in protein, mineral, and energy. Inventory control is affected by moisture content of feeds. Some feeds on hand are constantly changing in moisture content, and these changes frequently lead to financial losses when a price adjustment is not made for moisture losses.

G73-42 Slaughter Cattle Sale Choices (Revised June 1976), Allen C. Wellman

University of Nebraska-Lincoln Extension: Historical Materials

Cattle sold for slaughter can be sold either on a live or carcass weight basis. The ability to compare bid price for these two alternatives is necessary if the producer is to receive the maximum return from the cattle being sold. This publication discusses these choices for the livestock producer to use.

G73-20 Fertilizing Through Center Pivots, Paul E. Flschbach

University of Nebraska-Lincoln Extension: Historical Materials

There are two decisions and three sources of information that are needed before applying fertilizer solutions through a center-pivot sprinkler system. These are discussed in this publication.

The decisions are: the amount of nitrogen to be applied per acre through center-pivot sprinkler system; and the kind of fertilizer solution to be applied.

The information needed is: the number of acres that will be irrigated in one revolution of the center-pivot sprinkler system; the amount of time required to make one revolution of the center-pivot sprinkler system; and the rate at which your porportioning pump can inject a fertilizer solution into …

G73-58 Programmed Soil Moisture Depletion: Top Yields With Least Water (Revised), Paul E. Fischbach, Burt R. Sommerhalder

University of Nebraska-Lincoln Extension: Historical Materials

The development of automated irrigation has introduced a revised concept to irrigation water management that will mean savings of water and energy. By not completely refilling the root zone each irrigation, soil moisture storage capacity is left within the root zone to take advantage of any rainfall that occurs after an irrigation. Conservation of water is important because supplies are being depleted in many areas.

G73-66 Mound Design For Feedlots, Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

Shaping each feedlot pen to minimize mud problems is an important part of feedlot design.

Mud is our most costly weather hazard. Shaping each feedlot pen to minimize mud problems is an important part of feedlot design. While mud cannot be eliminated, proper shaping can reduce the number of days when it is a profit robber. And, proper shaping will also reduce the number of fly breeding areas within the pen, adding to summer comfort and gains. The cost is minimal at most locations if shaping is done before installing fencing, bunks, waterers and aprons.

G73-2 Fertilizer Management For Alfalfa (Revised August 1977), Delno Knudsen, George Rehm

University of Nebraska-Lincoln Extension: Historical Materials

Adequate soil fertility is necessary for alfalfa production on both dryland and irrigated soils of Nebraska. With adequate, but not excessive fertilizer programs, irrigated alfalfa should produce 6 to 8 tons per acre. Dryland alfalfa on the same soils should, on the average, produce 2 to 3 tons per acre.

This NebGuide covers the following areas for fertilizer management for alfalfa: soil and water tests, lime, fertilizer for establishment, phosphorus, potassium, sulfur, micronutrients, nitrogen recommendations and special problems.

G73-60 Working With Wood I. Home Drying Lumber (Revised July 1987), Michael Kuhns, Richard Straight

University of Nebraska-Lincoln Extension: Historical Materials

Avoid the expense of kiln-dried lumber by processing and drying your own lumber at home.

Anyone who has done much woodworking knows how expensive high quality, kiln-dried, hardwood lumber can be. Even kiln-dried construction lumber is expensive. Besides expense, there also may be problems with finding certain species of wood, highly figured wood, or hardwood boards thicker than one inch (4/4).

One way to avoid these problems is to dry your own lumber. Green, unsurfaced, or unplaned lumber can be obtained from many small sawmills in Nebraska and surrounding states. You may also want to obtain your own logs and …

G73-14 Grain Processing For Feedlot Cattle, Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

Several changes have occurred in the cattle feeding business which have focused attention on grain processing. The first of these was, the arrival of big feedlots provided an opportunity to use larger and more sophisticated processing equipment at reasonable cost per ton of feed produced. Also, the need to minimize feed separation and digestive disturbances encouraged the use of more sophisticated methods of processing.

A second development that is now focusing attention on grain processing is the rapidly increasing costs of equipment, fuel and labor involved in grain processing. In recent years, these have been increasing more rapidly than the …
