Ec98-793 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Worksheet 16: Crop Pesticide Application Management, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Why should I be concerned? Pesticides are important agricultural production tools that provide many benefits. Pesticides have been developed and used because human beings compete with insects, weeds, diseases and rodents for food, fiber and habitation. Proper management of these pests requires a responsible, systematic approach, which Integrated Pest Management (IPM) provides.

Ec98-791 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Worksheet 15: Irrigation Wellhead Protection, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Why should I be concerned? Nebraska’s 80,000+ irrigation wells can provide a direct conduit for contaminants to reach groundwater supplies unless properly located, constructed, and protected. Groundwater is the source of drinking water for essentially all of Nebraska’s rural residents and most residents of our towns and cities. It is critical that every effort be made to protect groundwater quality. Irrigation wells can be constructed and maintained to assure that groundwater quality is protected. Improperly constructed or maintained wells can allow bacteria, pesticides, fertilizers, oil products, or other pollutants to contaminate groundwater.

Ec98-790 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Worksheet 14: Crop Nutrient Application Management, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Why should I be concerned? Most Nebraska farmers apply some source of plant nutrients to help improve their crop production each year. Nutrients come from applied chemical fertilizers, manure or sewage sludge, and soil organic matter or legumes. When nutrients move off site or leach out of the root zone, they can pose a threat to the environment and the water we drink.

Ec98-789 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Fact Sheet 14: Improving Crop Nutrient Application Management, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Economics, energy and the environment are three primary reasons to be concerned about nutrient management, especially nitrogen (N) management. Nitrogen ranks high on a list of sixteen nutrients needed for the health of most plants, but unfortunately it also ranks high as a contaminant of Nebraska’s surface and groundwater. Most other nutrients occur naturally in the soil. Besides nitrogen, phosphorus and potassium are the nutrients most often added to Nebraska soils.

University of Nebraska-Lincoln Extension: Historical Materials

Stormwater is water from irrigation, rain or melting snow that does not soak into the ground. It flows from rooftops, over paved areas and bare soil, and across sloped lawns. As it flows, this runoff can collect and transport soil, pet waste, livestock manure, salt, pesticides, fertilizer, oil and grease, leaves, litter and other potential pollutants. A heavy rainstorm isn’t needed to send pollutants rushing toward streams, wetlands and lakes. A garden hose alone can supply enough water.

Nf98-375 What Is The "Cooperative Agreement" For Endangered Species Habitat Along The Central Platte River?, Gary R. Lingle, Thomas G. Franti

University of Nebraska-Lincoln Extension: Historical Materials

The governors of Nebraska, Colorado and Wyoming and the Secretary of the Interior signed a historic agreement on July 1, 1997. This agreement addresses endangered species issues affecting the Platte River Basin upstream of its confluence with the Loup River. The Cooperative Agreement for Platte River Research and Other Efforts Relating to Endangered Species Habitats Along the Central Platte River, Nebraska provides funding and an administrative structure to allow the states and the federal government to work together in enhancing water and land resources for endangered species. The agreement has two main objectives: 1. To develop and implement a "recovery …

G98-1355 Cropshare Leasing Patterns In Nebraska - 1996, Bruce B. Johnson, H. Douglas Jose, John D. Cole

University of Nebraska-Lincoln Extension: Historical Materials

Leasing agricultural land is very common in Nebraska. This NebGuide discusses the most common leasing arrangements in the state in 1996.

Nearly half, 47 percent, of Nebraska's agricultural land is leased each year; and of the cropland acreage, cropshare leasing remains the primary leasing arrangement used throughout most of the state. In cropshare arrangements, the landowner and the tenant agree to specific shares of the crop production as well as shares of certain key crop input costs. In principle, the division of the output between the landowner and the tenant should reflect the relative level of contributions of inputs each …

G96-1362 Soil Temperatures And Spring Planting Dates, Steven J. Meyer, Allen L. Dutcher

University of Nebraska-Lincoln Extension: Historical Materials

Dates on which soil temperatures reach a threshold value are presented as a spring planting guide for agronomic and horticultural producers.

For a seed to germinate it must have good contact with the soil and be placed in a favorable soil environment. A good soil environment is one that has suitable soil temperature, adequate soil moisture, good aeration, and for certain seeds, light. Conditions necessary for germination depend on the species and variety of seed being planted. Alone, none of these factors guarantee germination; rather it is the interaction of these factors that affects seed germination.

In Nebraska, soil moisture …

Nfs-1 Forestry Best Management Practices For Nebraska

University of Nebraska-Lincoln Extension: Historical Materials

A reference guide for loggers, landowners and managers.

Nebraska's Forest Resource

Forests cover 947,000 acres in Nebraska. Other land with scattered tree cover, including narrow wooded strips along streams, windbreaks, and wooded pasture lands, occupy an additional 1,252,000 acres. Managing Nebraska's forest lands can produce significant benefits without negative impacts; however, careless activities in woodlands can damage water resources, soils, wildlife habitat, aesthetic values, and even the ability to produce future benefits.

G96-1346 Plants For Shade Landscapes, Don Steinegger, Donald E. Janssen, Roch E. Gaussoin, Steven Rodie, Anne Streich

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide includes a plant list for shade landscapes.

While some may think of shade as a deterrent to gardening, it can be an asset if the special needs of shade-loving plants are considered. There are also ways to reduce the amount of shade, allowing more sunlight and air circulation into the landscape. To solve shade garden problems, shade's positive and negative aspects need to be considered.

G98-1372 Management Recommendations For Blocked-End Furrow Irrigation, Dean E. Eisenhauer, Brian L. Benham

University of Nebraska-Lincoln Extension: Historical Materials

Proper blocked-end furrow irrigation management practices can minimize water application, irrigation costs and the leaching of agri-chemicals below the root zone.

The goal of every irrigator should be to apply the right amount of water uniformly to meet crop needs. To do this, irrigators need to know how much water is applied and where it goes. In other words, they need to know how uniformly the irrigation water infiltrates into the soil profile. Achieving a uniform water application is not easy when using furrow irrigation. However, with a better understanding of how irrigation system management affects water distribution and a …

G98-1358 Feeding To Maximize Protein And Fat, Rick J. Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes feeding guidelines to increase milk fat and protein production.

Proper feeding management of dairy herds can both improve the economy of production and provide a healthier cow. To achieve these goals, producers must feed to increase production of milk with maximum levels of milk fat and protein.

Milk solids components include fat, protein, lactose and minerals. Normal values for milk fat range from 3.7 percent (Holstein) to 4.9 percent (Jersey); milk protein ranges from 3.1 percent (Holstein) to 3.8 percent (Jersey). Lactose is usually 4.6–4.8 percent for all breeds; minerals (ash) average .74 percent. Because current milk …
