G02-1466 Determining The Need To Fertilize Landscape Trees And Shrubs (Revised March 2004), Scott J. Dewald, Steven D. Rasmussen, Charles A. Shapiro, Scott J. Josiah

University of Nebraska-Lincoln Extension: Historical Materials

Most Nebraska soils are fertile enough to support tree and shrub growth without applying fertilizer. However, when woody plants exhibit poor growth or reduced vigor, yet have had adequate moisture and are not experiencing pest problems or other environmental limitations, the proper applicatin of fertilizer may be necessary. This NebGuide explains how to determine if fertilization of established trees and shrubs is required and how to apply the needed amount.

G96-1306 Feeding Dairy Cows To Reduce Nitrogen, Phosphorus, And Potassium Excretion Into The Environment, Rick J. Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses feeding strategies to optimize dairy cow performance while minimizing negative environmental impacts.

Reducing N, P and K Excretion--The Challenge

Increasingly, our society demands livestock production systems that not only produce economic, high-quality food products, but also minimize negative environmental impacts. Feeding management has improved continuously and helps explain increases in milk production averages. The future challenge for dairy producers and nutritionists will be to properly formulate rations for high production levels while simultaneously minimizing the environmental impact of excessive N, P and K excretion in the urine and manure. A realistic approach will be to keep formulation …

G90-978 Byproduct Feedstuffs For Beef And Dairy Cattle, Don J. Kubik, Rick Stock

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide details the type of byproduct feedstuffs available for beef and dairy cattle, a description of their characteristics and discussion of their nutrient value. Byproduct feeds have become a stabilizing factor in the economic success of many beef and dairy operations. Byproduct feeds are the residue that remains after feeds have been processed. The processing of soybeans into soybean meal results in a large supply of soybean hulls. Processing corn into high fructose syrup provides corn gluten feed and corn bran. Converting corn starch into ethanol provides distillers grains. Hominy, a byproduct of processing corn starch for human consumption, …

G79-430 Oat Production In Nebraska (Revised March 1992), Russell Moomaw, Charles A. Shapiro

University of Nebraska-Lincoln Extension: Historical Materials

Information is provided for various oat production practices including seed selection, fertilizing, planting, weed control and harvest. Oats were among the first crops grown by pioneers who settled eastern Nebraska. As recently as 1950, Nebraska produced 2.7 million acres of oats. Acreage has declined steadily, however, and in 1990 there were just 300,000 acres. Oats are grown throughout the state, with the majority being in eastern Nebraska where the cool, moist climate provides for the best growth. The feed value of oats also favors its production in northeast Nebraska where swine, dairy cattle, and beef cattle production are heavy. An …

G77-350 Mineral Nutrition Of Range Beef Cattle, Marvin W. Heeney

University of Nebraska-Lincoln Extension: Historical Materials

Minerals play a very important role in the well-being of the range beef herd. Minerals are essential for practically all of the metabolic functions of the beef animals. Minerals are classified as 1) major and 2) minor or trace. The major minerals include calcium, phosphorus, magnesium, sodium, potassium, chlorine and sulfur. The trace minerals include copper, cobalt, iodine, iron, manganese and zinc.

Each mineral is discussed here in terms of its function, deficiency symptoms and availability in the range beef cattle diet.

G74-174 Fertilizer Suggestions For Corn (Revised November 2003), Charles A. Shapiro, Richard B. Ferguson, Achim R. Dobermann, Charles S. Wortmann

University of Nebraska-Lincoln Extension: Historical Materials

Fertilizer nutrient requirements for corn are based on expected yield and nutrient levels in the soil. Crop production in Nebraska typically requires applying nitrogen to supplement that available in the soil. Phosphorus is the second most likely nutrient to be deficient in the soil for good corn yields.

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.

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.

Ec31-133 The Management Of Nebraska Soils (Revised March 1936), P.H. Stewart, D.L. Gross

University of Nebraska-Lincoln Extension: Historical Materials

The agricultural lands of this country are its greatest natural resource. History points out that nations with vast areas of good farm land are most likely to prosper and survive over long periods of time. Local communities, too, prosper and flourish in proportion to the productiveness of the surrounding land. Schools, social life, and business develop best in areas where the land is productive and properly managed and conserved.

Nebraska, in common with other states, has suffered by the depletion of soil fertility. The reduction in acres in legumes and grasses, and the deplation of the organic matter in the …
