Cc90-342 Soil Compaction...Fact And Fiction: Common Questions And Their Answers, Alice J. Jones, Robert D. Grisso, Charles A. Shapiro

University of Nebraska-Lincoln Extension: Historical Materials

What causes soil compaction? Compaction occurs when soil particles move closer together because of external forces exerted by humans, animals, equipment and water droplets. It can be found on the soil surface and at almost any depth. Compacting soils leads to conditions that are less than optimum for crop growth, soil water management and efficient use of agricultural chemicals.

University of Nebraska-Lincoln Extension: Historical Materials

Proper nut cultivar (variety) selection is important for successful and satisfying results from the home gardener's efforts.

G90-963 Narrow-Row Soybeans, Roger Wesley Elmore, Russell S. Moomaw, Roger Selley

University of Nebraska-Lincoln Extension: Historical Materials

Narrow-row spacing of soybeans may be a profitable practice with modern herbicides and new lodging-resistant varieties. This NebGuide describes considerations for producing narrow-row soybeans. Early in this century crop row spacing was determined by the breadth of the animals used to work the fields. Spacing had an impact on methods of weed control and the varieties of soybeans developed. Even a decade ago row spacing was determined by tractor tire size since cultivation was required. Also, the tall varieties of soybeans lodged severely in narrow-row systems. However, the broad spectrum of herbicides now available and lodging-resistant soybean varieties have made …

G90-992 Evapotranspiration (Et) Or Crop Water Use, Norman L. Klocke, Kenneth Hubbard, William L. Kranz, Darrell G. Watts

University of Nebraska-Lincoln Extension: Historical Materials

What must irrigators consider in the most efficient use of water? Read on.

Irrigators in the Great Plains have two major challenges in the years ahead:

1. Maintain groundwater quality by adjusting management to minimize the leaching of agri-chemicals from the crop root zone;

2. Continue profitable production in the face of a less abundant and increasingly costly water supply.

Irrigators must learn to convert water to grain the most efficient manner possible. Applying only enough water to meet full evapotranspiration (ET) of the crop is one key to efficient water use (ET is also called crop water use.)
