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 …

G79-430 Oat Production In Nebraska (Revised March 1992), Russell Moomaw, Charles A. Shapiro Jan 1979

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 …

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 Jan 1974

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.

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 …
