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 …

G73-42 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.

G73-58 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.

G73-2 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.
