University of Nebraska-Lincoln Extension: Historical Materials

Why is the site evaluation important? The effect of farm, ranch or homesite practices on groundwater depends in part on the physical characteristics of your site: soil type, subsurface characteristics and depth to groundwater. That’s why evaluating the soils and geologic characteristics of your site is such an important step in protecting the groundwater you drink. This evaluation focuses primarily on the farmstead or homesite and risk to groundwater, but, to a limited extent, also addresses surface water. The worksheet can be applied to land beyond the farmstead or homesite, but the variation in soils and geologic materials would have …

Bioavailability Of Nutrients And Metals Following Land Application Of Organic Wastes, Jianqiang Zhao

Doctoral Dissertations

Field, greenhouse and laboratory studies were conducted to investigate the effects of soil-incorporated organic wastes on nitrogen release patterns, groundwater nitrate-nitrogen levels, nutrient/metal uptake, and plant yield.

Three field studies with corn (Zea mays L.) were conducted during 1993 to 1997 at three locations in New Hampshire using a randomized complete block design with three or four replications, two or three waste materials as main plots, and various application rates as subplots. Compared to dairy manure, Concord biosolids showed a slower release rate measured as soil NO$\sb3$-N concentrations in early season but higher post-harvest levels of soil NO$\sb3$-N.

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.

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.

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.

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.

The biological properties of these isolates and those of a mechanically transmitted virus obtained from I. purpurea were compared with a previously characterized sweet potato feathery mottle virus strain (SPFMV-C) from North Carolina. The symptoms induced in a range of hosts indicated that two of the isolates were associated with russet crack symptoms in the cultivar Jersey; however, none of them could be associated with …

Quantifying Sustainability In Aquaculture Production., Rex Hall Caffey

LSU Historical Dissertations and Theses

Despite increasing institutional focus in aquaculture, sustainability remains an amorphous and much debated concept. Little consensus has been identified on the issue beyond the general recognition that the concept should contain environmental, economic, and sociological considerations. This study addressed the specific, relevant question of whether politically diverse aquacuiture interests can collectively develop and agree on production-level goals and indicators of aquaculture sustainability. The research partitioned sustainability into its three subcategories: environmental, economic and social. This division facilitated the use of existing conventions of measurement and expression in each subcategory. Employing a modified Delphi technique, over 100 aquaculture stakeholders in the …
