Ec89-724 Irrigation Scheduling Using Tensiometers In Sandy Soils, William L. Kranz, Thomas Dorn, Dean E. Eisenhauer
University of Nebraska-Lincoln Extension: Historical Materials
Monitoring soil moisture is fundamental to determining how much irrigation water should be applied and when the soil is able to store the amount of water to be applied. Establishing when and how much water should be applied is often referred to as irrigation scheduling.
This extension circular discusses soil moisture terms; what is a tensiometer, its installation and use; and worksheet.

Causes of crown and upper root rot, symptoms and management are discussed here.
Alfalfa (Medicago sativa L.) is the most important forage crop species in North America. It is widely adapted, energy efficient, and produces the most protein yield per acre. Alfalfa is well-suited to both dryland and irrigationd soils of Nebraska.
Many factors contribute to the decline in productivity of an alfalfa stand. Under favorable growing conditions and proper management, alfalfa stands in Nebraska can last over 10 years.
G89-901 Understand Your Soil Test: Sulfur, K.D. Frank, Delno Knudsen
G89-901 Understand Your Soil Test: Sulfur, K.D. Frank, Delno Knudsen
University of Nebraska-Lincoln Extension: Historical Materials
Factors leading to sulfur deficiency, soil and water tests, soil test interpretation and fertilizer materials that contain sulfur are covered here.
Sulfur, one of the macro-nutrients, may be deficient in some sandy soils but usually is plentiful in other soils of the state. The amounts contained by healthy crops are on the same order as phosphorus, ranging from 0.2 percent to .5 percent sulfur. It is a component of certain amino acids, and so is part of several proteins essential for plants and animals.
