Tallgrass Prairie Vegetation Response To Spring Burning Dates, Fertilizer, And Atrazine, Robert B. Mitchell, Robert A. Masters, Steven S. Waller, Kenneth Moore, Linda J. Young
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Tallgrass prairies provide an important source of hay and summer forage in eastern Nebraska. A study was conducted in 1989 and 1990 on 2 late seral tallgrass prairies near Lincoln and Virginia, Nebraska to determine if production of selected components of tallgrass prairie communities could be altered by burning (not burned, or burned in either early, mid-, or late spring) and applying fertilizer (0 and 67-23 kg N-P ha-1) and atrazine [6- chloro-N-ethyl-N'-(1-methylethyl)-1,3,5-triazine-2,4-diamine] (0 and 2.2 kg a.i. ha-1). Vegetation was harvested the year treatments were applied at about 30-day intervals starting in June and ending …

G96-1279 Drinking Water: Nitrate-Nitrogen (Revised November 1998), Paul J. Jasa, Sharon Skipton, David L. Varner, Delynn Hay
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide discusses practices recommended to manage nitrate-nitrogen in a domestic water supply. Many Nebraskans have questions about the impact of nitrate in their drinking water. Water quality monitoring shows that nitrate is present in groundwater throughout much of Nebraska and that concentrations are increasing in some areas. Nitrogen is essential for all living things as it is an essential component of protein. Nitrogen exists in the environment in many forms and changes forms as it moves through the nitrogen cycle. However, excessive concentrations of nitrate-nitrogen in drinking water can be hazardous to health, especially for infants and pregnant women.

This NebGuide discusses feeding strategies to optimize dairy cow performance while minimizing negative environmental impacts.
Reducing N, P and K Excretion--The Challenge
Increasingly, our society demands livestock production systems that not only produce economic, high-quality food products, but also minimize negative environmental impacts. Feeding management has improved continuously and helps explain increases in milk production averages. The future challenge for dairy producers and nutritionists will be to properly formulate rations for high production levels while simultaneously minimizing the environmental impact of excessive N, P and K excretion in the urine and manure. A realistic approach will be to keep formulation …
