Adding Value To Swine Manure Through Accurate Prediction Of Organic Nitrogen Availability, Charles S. Wortman, Charles Shapiro, Aaron Nygren

Department of Agronomy and Horticulture: Faculty Publications

Animal manure contains organic and inorganic nitrogen. The inorganic N, which is mostly ammonium-N but nitrate-N can be significant in composted manure, is typically considered to be 100% plant available if there are not significant losses, especially due to volatilization of ammonia-N. The availability of organic N, which is mostly from undigested and partially digested plant material needs to be mineralized to become plant available, is less predictable. Field research was conducted in eastern Nebraska to improve the basis for estimating organic N availability from injected or incorporated swine manure and from surface applied composted and stockpiled FM. The factors …

Sorghum Lager And Stout Beer: A Boost To The African Economy, Intsormil

INTSORMIL Impacts and Bulletins

For millennia, sorghum has been the basis of traditional African beers such as the clear beers of West Africa (dolo and pito) and the opaque beers of southern Africa. These beers are part of the African tradition and remain very popular but today Africans also enjoy lager and stout beers. These beers, of European origin, use barley as their major ingredient. This presents a major problem as barley is a temperate cereal and the African climate is unsuitable for cultivation. Thus, barley grain or barley malt must be imported which requires the use of valuable foreign exchange and increases the …

Ethylene Production As An Indicator Of Stress Conditions In Hydroponically-Grown Strawberries, Justin Donald Hogan

Theses, Dissertations and Capstones

With the worldwide phaseout of methyl bromide, the use of hydroponic systems has increased as an economic alternative for the growth of many horticulturally-important crops, including strawberries. In this study, the effect of hydroponics on strawberry plant physiology was examined by first measuring ethylene levels, a plant hormone known to increase due to stressful conditions, and plant growth and yield. Using a gas chromatograph, ethylene was measured from plants which showed that light and temperature have minimal effects, but placement of plants could have an effect on plant growth and yield. Next, the mechanism of ethylene production was examined by …
