The Effect Of 2,4-D, Grazing Management And Nitrogen Fertilizer On Pasture Production, M. K. Mccarty, M. L. Cox, D. L. Linscott

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Many pastures in eastern Nebraska and surrounding areas have gradually decreased in productivity. Over a long period of heavy grazing, native warm-season grasses have been largely replaced with Kentucky bluegrass, other less desirable grasses, and broadleaf weeds. A program was started in 1949 to study the effectiveness of protection from grazing in changing the botanical composition and yield of a pasture where the predominant forage was Kentucky bluegrass. Several weed control treatments were included in this experiment to determine if mowing or spraying would hasten the return of more desirable forage. After weed control and differential grazing treatments had been …

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.

G74-131 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 …

G74-174 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.
