A field study was conducted at the Department of Agricultural Education Experimental Farm at Institute of Ecumenical Education Thinker’s Corner Enugu South Eastern Nigeria to investigate the effect of different sources of animal wastes on the growth and yield of Okra. The experiment was laid out in a Randomized complete Block Design (RCRD) with four replicates, Poultry manure (12KgPM/plot), Pig...

Anaerobic digestion is an efficient and renewable energy technology that can produce biogas from a variety of biomasses such as animal manure, food waste and plant residues. In developing countries this technology is widely used for the production of biogas using local biomasses, but there is little information about the value of these biomasses for energy production. This study was therefore c...

Livestock odors are closely correlated to airborne concentrations of volatile organic compounds (VOC), which are a complex mixture of carbon-, sulfur-, and nitrogen-containing compounds produced primarily during the incomplete anaerobic fermentation of animal manure by microorganisms. Volatile fatty acids, alcohols, and aromatic ring compounds comprise a substantial fraction of VOC, yet very li...

Understanding the environmental pathways of Cryptosporidium is essential for effective management of human and animal cryptosporidiosis. In this paper we aim to quantify livestock Cryptosporidium spp. loads to land on a global scale using spatially explicit process-based modeling, and to explore the effect of manure storage and treatment on oocyst loads using scenario analysis. Our model GloWPa...

In most phosphorus (P) sorption studies, P is added as an inorganic salt to a predefined background solution such as calcium chloride (CaCl2) or potassium chloride (KCl); however, in many regions, the application of P to agricultural fields is in the form of animal manure. The purpose of this study, therefore, was to compare the sorption behavior of dissolved reactive P (DRP) in monopotassium p...

BACKGROUND: Vermicompost has many characteristics such as high porosity, ventilation and proper drainage, high moisture absorption and maintenance power, high uptake level for water and food stuffs, and its use in sustainable agriculture is very useful to improve soil porosity and thus more availability of nutrient elements required by plants. Manure plays an important role in ...

Many studies on methane (CH4) and nitrous oxide (N2O) emissions from livestock industries have revealed that livestock production directly contributes to greenhouse gas (GHG) emissions through enteric fermentation and manure management, which causes negative impacts on animal environment sustainability. In the present study, three essential values for GHG emission were measured; i.e., i) maximu...

Many environmental problems of current concern are due to the high production and local accumulations of organic wastes that are too great for the basic degradation processes inherent in nature. With adequate application rates, animal manure constitutes a valuable resource as a soil fertilizer, as it provides a high content of macroand micronutrients for crop growth and represents a low-cost, e...

PM 1970a July 2004 Practices to control odor emissions associated with livestock production can be applied to animal housing areas, manure storage areas, and land where manure is applied. This document provides an overview of practices for each situation, highlights their advantages and disadvantages, and provides producers with sufficient information to make informed choices after evaluating p...

In this study, the kinetic of biogas production was studied by performing a series laboratory experiment using rumen fluid of animal ruminant as inoculums. Cattle manure as substrate was inoculated by rumen fluid to the anaerobic biodigester. Laboratory experiments using 400 ml biodigester were performed in batch operation mode. Given 100 grams of fresh cattle manure was fed to each biodigester...
