Contamination by bacteria is a leading cause of impairment in U.S. waters, particularly in areas of livestock agriculture. We evaluated the effectiveness of several practices in reducing Escherichia coli levels in runoff from fields receiving liquid dairy (Bos taurus) manure. Runoff trials were conducted on replicated hay and silage corn (Zea mays L.) plots using simulated rainfall. Levels of E...

BACKGROUND: The ability of a plant to resist or tolerate pests is grounded partially in favorable physical, chemical and biological properties of soil. OBJECTIVES: Investigate the influence of nutrient sources on Podagrica uniforma and Nisota dilecta infestation, population dynamics and performances of okra. METHODS: </stro...

Traditional corn (Zea mays L.) (TC), the primary grain used in swine (Sus scrofa) diets, stores a majority of its P as phytate, which is largely unavailable for digestion by nonruminant animals. Low-phytate corn (LPC) contains similar amounts of total P but a smaller percentage of P as phytate. When fed to swine, LPC increases P utilization and reduces P content of manure. While differences in ...

in order to investigate the effects of high corm planting density and applying manure on flower and corm yields of saffron (crocus sativus l.), a field experiment was conducted at research station, faculty of agriculture, ferdowsi university of mashhad, iran, during growing season of 2010-2011. a completely randomized block design with three replications and 20 treatments was used. the experime...

Phosphorus (P) runoff from fields fertilized with swine (Sus scrofa domesticus) manure may contribute to eutrophication. The objective of this study was to evaluate the effect of aluminum sulfate (alum) and aluminum chloride applications to swine manure on P runoff from small plots cropped to tall fescue (Festuca arundinacea Shreb.). There were six treatments in this study: (i) unfertilized con...

Due to the increase in environmental problems and air pollution during the heating period, it is important to promote clean heating in cold regions, thereby meeting the heating demand in a green manner. In order to allocate resources more effectively and facilitate the consumption of renewable energy, this paper designs an integrated heating system that incorporates geothermal energy into the f...

OBJECTIVES Liquid manure systems and manure pits are major hazards in the agricultural workplace. The incidence of accidents related to manure is unknown. The objective of this study was to survey the liquid manure facilities of farms in eastern Switzerland and find the incidence of accidents related to manure in the region. METHODS Retrospective cohort study and cross sectional survey of 210...

abstract use of organic fertilizer in production of organic products is important. a field experiment was conducted to investigate the effect of different levels of poultry manure on some growth characteristics and crop yield of iranian melons. the design was split plot in a randomized complete block design with four replications. levels of poultry manure (pm) included: 0, 5, 10, 15 and 20 tons...

Introduction ield experience and research demonstrate that manure nutrients can be readily substituted for commercial fertilizer. Fertilizer needs depend on soil test levels. Substituting manure at a lower cost than commercial fertilizer can result in signifi cant savings if relatively uniform application and distribution can be maintained. The less nutrient-dense manure requires more hauling o...
