Ec92-124 Nebraska Handbook Of Range Management, James L. Stubbendieck, Patrick E. Reece

University of Nebraska-Lincoln Extension: Historical Materials

Every Nebraskans should be interested in rangeland. The plants, soil, and water are the foundation of Nebraska's economy and quality of life. Rangeland is one of Nebraska's most important and valuable natural resources because it:

• produces forage for livestock and wild game;

• provides a varied habitat for many wildlife species;

• protects the soil from wind and water erosion;

• preserves a "germplasm bank" for many plant species that may become important for yet unknown uses;

• purifies and enhances the environment by cleasing the air, filtering the runoff to streams, increasing the intake of precipitation, and aiding …

How to grow successfully broccoli, brussels sprouts, cabbage, cauliflower, and kohlrabi.

Cole crops, which include broccoli, brussels sprouts, cabbage, cauliflower, and kohlrabi, can be successfully grown on most soils if drainage is good and the crop is supplied with adequate water and nutrients, particularly nitrogen. Light-textured soils usually produce earlier crops but heavier soils hold more moisture and tend to produce crops that hold quality longer at maturity.

Cole crops have shallow root systems. Inadequate moisture may cause small cauliflower heads to form prematurely. Rainfall or irrigation following a prolonged dry spell may cause splitting of cabbage and kohlrabi. Supplemental …

G92-1094 Controlling External Swine Parasites, John B. Campbell, Barbara Straw

University of Nebraska-Lincoln Extension: Historical Materials

Mixing, safety, restrictions, and precautions for insecticides used to control external swine parasites.

Hog Lice and Mange Mites

External parasites of swine include the hog louse and two species of mange mites (the common itch mite and the less common hog follicle mite). Excessive scratching and rubbing by pigs nearly always indicate an infestation of hog lice or mange mites.

Hog lice and mange mites infest a high percentage of swine slaughtered at Midwest slaughter plants.
