Global increases in consumption of chemical nutrients, application of pesticides, and water withdrawal to enhance agricultural yield have resulted in degraded water quality and reduced water availability. Efforts to safeguard or improve environmental conditions of agroecosystems have usually focused on managing on-farm activities to reduce materials loss and conserve habitat. Another management...
Toxoplasmosis has been reported to occur in several animals and humans causing different clinical manifestations. The study was conducted to determine the frequency of Toxoplasma gondii antibodies (IgG) in water buffalo (Bubalus bubalis) across farms in Trinidad using a latex agglutination test. Of a total of 333 water buffalo tested, 26 (7.8%) were seropositive for T. gondii antibodies. Seropo...
Efforts to exclude disease organisms from farms growing irrigated lettuce and leafy vegetables on California's central coast are conflicting with traditionally accepted strategies to protect surface water quality. To begin resolving this dilemma, over 100 officials, researchers, and industry representatives gathered in April 2007 to set research priorities that could lead to effective co-manage...
Many measures have been proposed to mitigate gaseous emissions and other nutrient losses from agroecosystems, which can have large detrimental effects for the quality of soils, water and air, and contribute to eutrophication and global warming. Due to complexities in farm management, biological interactions and emission measurements, most experiments focus on analysis of short-term effects of i...
The organizational injury theory focusing on management issues could provide new viewpoints on causes and prevention of injuries in agriculture. The objective of this study was to test whether the quality of farm management is associated with farm injuries. A cohort of 134 farms was used to examine the relationship between farm injuries and selected management, farm, and farm operator character...
This study was on the analysis of livestock waste management practices among rural farmers in Abia State, Nigeria. A multi-stage sampling procedure was employed to select the 60 respondents for the study. Primary data used the study were collected using well-structured questionnaire. Descriptive statistical tools such as frequency counts, percentages, means, and multinomial logit regression wer...
This paper presents a model of the farm management process. The model suggests that certain socioeconomic characteristics of farm managers will influence their decision-making process. Several characteristics are hypothesized and tested using multivariate techniques (multivariate analysis of variance, range tests, and multiple comparisons). The analysis indicates that the soil zone, value of ma...
The fast changing environment, including difficult market conditions and a high exposure to financial risks are major reasons for changing production policy. Farm Management Information Systems (FMIS) appear to be a powerful tool to deal with the new conditions. However, farmers still rely more on their intuition than on proper management tools, when it comes to running a farm business. Many fa...
The virtual elimination of the principal point sources of human bacterial pollution through advanced treatment systems has not produced 100% compliance with microbial standards at all UK bathing water locations where they have been installed. This is partly explained by the existence of diffuse bacterial pollution derived from agricultural activities within catchments draining to the bathing zo...
