Ec98-750 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Risk Worksheet 12: Silage Storage, 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? Silage is an important feed for livestock-based agriculture. When properly harvested and stored, silage poses little or no pollution threat, but improper handling can lead to a significant flow of silage juices (or leachate) from the silo. Leachate is an organic liquid that results from pressure in the silo or from extra water entering the silo. It is usually a problem only when silage is fresh, or just after storage. This loss of leachate represents a loss of nutrient value from the silage.

Ec98-754 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Risk Worksheet 7: Hazardous Materials And Waste 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? Consider the variety of products commonly used in households, on acreages and on farms: paints, solvents, oils, cleaners, wood preservatives, batteries, adhesives, and pesticides. Also consider the amount of these products which goes unused or is thrown away. Some common disposal practices can create an unsafe environment around the home and may contaminate groundwater. Additionally, many of these common disposal practices violate Nebraska law.

Ec98-751 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Risk Fact Sheet 9: Improving Livestock Manure Storage, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Manure storage is an important manure management option for livestock producers. Stored manure can be applied to the soil when nutrient uptake by crops can be maximized and weather related losses minimized. Preplant applications of manure incorporated into the soil ensures maximum crop nutrient value, while reducing risks of water contamination.

Ec98-756 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Risk Worksheet 13: Milking Center Effluent Treatment, 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? Milking center effluent is usually considered a dairy sanitation problem. If not properly managed, however, the effluent can contaminate both groundwater and surface water.

Ec98-766 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Worksheet 3: Drinking Water Well Condition, 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? Essentially all of Nebraska’s rural residents use groundwater to supply their drinking water and farm needs. Wells should provide clean water. If wells are improperly constructed or maintained, however, they can allow bacteria, pesticides, fertilizer, oil products, or other pollutants to contaminate groundwater. These contaminants can put family, pets and livestock health at risk.

Ec98-763 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Worksheet 6: Petroleum Product Storage, 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? Aboveground and underground storage of liquid petroleum products such as motor fuel and heating fuel presents a threat to public health and the environment. Nearly one out of every four underground storage tanks in the United States may now be leaking, according to the U.S. Environmental Protection Agency. If an underground petroleum tank is more than 20 years old, especially if it’s not protected against corrosion, the potential for leaking increases dramatically. Newer tanks and piping can leak, too, especially if they were improperly installed.

Ec98-761 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Worksheet 10: Livestock Yards 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? Livestock yards, such as barnyards, holding areas and feedlots, are areas of concentrated livestock wastes and a potential source of nutrient, solids, and bacteria contamination of surface and groundwater. Yards that are abandoned permanently or are inactive temporarily also represent a potential risk.

Ec98-792 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Fact Sheet 16: Improving 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

Though pesticides are especially harmful to the target pest, they are also potentially harmful to most living and breathing creatures and non-target plant life. Proper handling and application management of pesticides are important to protect you and to protect surface and groundwater from contamination. Pesticides were first found in groundwater in the 1970s. Prior to that, the general belief was that pesticides did not leach into the groundwater with normal use.

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.

Ec98-796 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Worksheet 17: Stormwater Management At Residential Sites, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

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.

Nf98-372 Preparation And Use Of Wheatgrass Stands After Crp And Associated Costs/Income — Part I, Patrick E. Reece, Tom Holman, David W. Cook

University of Nebraska-Lincoln Extension: Historical Materials

Wheatgrass species (Agropyron spp.) were seeded on many Conservation Reserve Program (CRP) acres in western Nebraska and adjoining states. These species included crested (A. cristatum, desertorum), intermediate (A. intermedium), pubescent (A. trichophorum) and western (A. smithii) wheatgrasses. Good to excellent stands of wheatgrass can be valuable forages sources for livestock during the spring, summer, or fall, however, accumulation of large amounts of poor quality residual herbage during 10-year CRP contract periods can reduce animal performance.

This NebGuide discusses field evaluations, results, recommended preparations, spring and summer grazing after CRP; and associated …

Validating A Vegetative Filter Strip Performance Model, Puneet Srivastava, Thomas A. Costello, Dwayne R. Edwards, James A. Ferguson

Biosystems and Agricultural Engineering Faculty Publications

Vegetative filter strips (VFS) reduce losses of nutrients, solids, and other materials from land area treated with fertilizers and manures. A number of models are available that simulate nutrient and sediment transport in VFS. While VFS effectiveness is considered to depend on lengths of pollutant source area and VFS areas, few published studies have tried to validate these models using variable pollutant source area and VFS area. The objective of this study was to validate an event-based nutrient transport model (Chaubey et al., 1995) that simulates soluble nutrient transport in VFS. This model links three sub-models: modified Green-Ampt infiltration, non-linear …

A State-Dependent Model Of Forest Floor Development, Ertuğrul Bi̇lgi̇li̇

Turkish Journal of Agriculture and Forestry

A state-dependent, dynamic forest floor development model is presented. The model considers litterfall as input. The decomposition of the litter was modelled as influenced by the quality of litter and miccroclimatic conditions (temperature and moisture). Microclimatic conditions were determined based on weather data and stand structure. The predictions of the model compared with an independent data set suggested that the model functions realistically under a range of weather and stand conditions. The resulting model should be valuable in the prediction of fire behavior.

Turkish Journal of Agriculture and Forestry

Some quality characteristics of frankfurter type sausages (with 30% total fat) produced by adding sunflower oil at different levels (10%, 20% and 30%) were determined and compared to control with 30% animal fat. Increasing of sunflower oil content resulted in lower process yield. Cholesterol content and water holding capacity of frankfurters also decreased at the levels of sunflower oil from 10 to 30% (P

Seed Vigor Of Four Isoline Pairs Of Sweet Corn With Two Endosperm Types At Four Temperatures, Ronglin Wang

Masters Theses

Sweet corn (Zea mays L. var rugosa ) is the fourth most important fresh vegetable in the U.S.. Supersweet corn with shrunken-2 endosperm is more popular with consumers than traditional sweet corn with sugary endosperm because sh2 kernels have more sugars and retain this sweet flavor longer than su kernels. However, its acceptance by growers is hindered because of its inferior seed quality and poor seedling vigor, especially when temperature is low.

Seed vigor of four isoline pairs ( C68, Oh43, Il442a and Ia453 ) with two endosperm types ( sh2 and su ) was studied in this investigation. In …

Resource management technical reports

High water use vegetation systems for salinity control were trialed on a 70 ha catchment located about 15 km north of Williams, Western Australia. The catchment receives about 545 mm annual rainfall and 1870 mm annual evaporation. Development of salinity is characterised by passive discharge upslope from a dolerite dyke. Because recharge exceeds the discharge capacity of current seeps, there is potential for new seeps to develop in the mid to lower slopes.
