Distributions, Densities, And Relative Abundances Of Grasshoppers (Orthoptera: Acrididae) In A Nebraska Sandhills Prairie, Anthony Joern

Entomology Papers from Other Sources

Grasshoppers (Orthoptera: Acrididae) represent a conspicuous and often important component of grassland systems (Odum et al. 1962, Smalley 1960, Sinclair 1975, Van Hook 1971, Wiegert 1965). Often, assemblages of grasshoppers are quite diverse and may, on occasion, consume a large fraction of the available vegetation (Hewitt 1977, Hewitt et al. 1976, Mitchell and pfadt 1974). As such, grasshoppers have the potential of being very important in the nutrient and energy flow in grassland ecosystems. However, to understand the impact of grasshoppers at the ecosystem level requires that the densities and fluctuations of populations as well as the species composition of …

Ec82-1738 Tree Planting Guide, William R. Lovett, Bruce E. Bolander

University of Nebraska-Lincoln Extension: Historical Materials

Site Preparation

Proper site preparation is essential to your tree planting operation, and varies with the different climates and soil types.

Chemical Control: On sandy soils, rough terrain, or other highly erodible sites, tillage is not recommended. Chemical weed and/or grass killers may be applied to the site in the fall or before planting in the spring.

Summer Fallow: This practice is recommended on heavy soil in western Nebraska to conserve soil moisture. This may be accomplished with the aid of occasional disking, subsurface tillage, or chemicals to control weeds.

Fall Tillage: In the eastern areas of the state fall …

G82-602 Predicting The Last Irrigation For Corn, Grain Sorghum And Soybeans (Revised August 1991), Norman L. Klocke, Dean E. Eisenhauer, Terry L. Bockstadter

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide presents criteria and "rules of thumb" for predicting the last irrigation for corn, grain sorghum and soybeans.

Determining when to apply the last irrigation of the season is an important water management decision. One extra irrigation may mean wasting an additional one to three inches of water and two to five gallons of diesel fuel per acre. On the other hand, applying that one extra irrigation could mean several bushels per acre in crop yield.

G82-587 Understanding Potassium For Crop Production In Nebraska, George W. Rehm

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the availability of and the need for potassium in Nebraska soils

Potassium (K) is an essential nutrient absorbed from soils by crops in relatively large amounts. Therefore, it is classified as a major nutrient. Although large amounts are absorbed, potassium is not necessarily needed in a fertilizer program. Numerous studies conducted with all major crops have definitely shown that adding potassium to a fertilizer program does not lead to yield increases on the large majority of soils in Nebraska.
