This paper aims to construct an empirical model for the analysis of two principal simultaneous decisions of farm operators: participation in the off-farm labor market, and the amount of resources to invest in farm capital. We first develop a theoretical model analyzing the effects of exogenous shocks on farmers’ decisions. Then, we estimate jointly a multinomial probit model of farmers’ off-far...
OBJECTIVE Develop and test a farm health and injury prevention educational intervention for high school agriculture students. SETTING Twenty one high schools in Kentucky, Iowa, and Mississippi. METHODS A quasiexperimental crossover design was used to test the effectiveness of two sets of instructional materials designed through participatory action research with agriculture teachers and stu...
The extent to which farm families engage in off-farm employment activities is a topic of central importance to understanding the financial well-being of farm households. The degree of financial stress experienced by U.S. farm families is always a concern to policy makers. Yet, policy considerations often ignore the substantial involvement of most farm households in nonfarm labor markets. It has...
BACKGROUND The Swedish control program for salmonella includes restrictions and on-farm control measures when salmonella is detected in a herd. Required control measures are subsidised by the government. This provides an opportunity to study costs for on-farm salmonella control. The aim of this study was to describe the costs for on-farm salmonella control in Swedish cattle herds and to investi...
The paper describes the hierarchical control concept for wind farm power/load optimization with emphasis on compensation of disturbances. The control concept was developed for the EU-FP7 project Distributed Control of Large-Scale Offshore Wind Farms – Aeolus. The Aeolus project approaches the wind farm control problem by considering wind turbines in a wind farm as individual power actuators aff...
The article investigates the investment and financial constraints for French, Hungarian and Slovenian farms using FADN panel data with different econometric estimation approaches. Farm gross investment is positively associated with real sales growth and cash flow implying the absence of soft budget constraint. Gross farm investment is positively associated with investment subsidies. Specific re...
Fecal egg count reduction tests (FECRT) and larval migration inhibition tests (LMIT) were conducted to assess the efficacy of ivermectin (IVM) against gastrointestinal nematodes on 2 cattle farms in northern Japan in 2009 and 2010. Twelve to 20 calves on each farm were treated topically with 0.5 mg IVM/kg 2 (Farm 2) or 4 times (Farm 1) during the grazing season (May-October). On Farm 1, fecal e...
Rollover protective structures (ROPS) are an effective engineering control known to prevent tractor overturn deaths, the leading cause of occupational fatalities for farmers and farm workers in the U.S. However, the use of ROPS is known to vary greatly from farm to farm. A national sample of 11,458 farm operators from the 2004 Occupational Injury Surveillance of Production Agriculture (OISPA) s...
In order obtain suitable and effective farm machinery performance besides higher crop yield, on time farm machinery field operations are essential. Farm tractors are important machines that used for soil tillage, crop planting and protection. It is even used for harvesting crops in some areas. Thus, any failure in farm tractors influences the series of field operations. Farm managers are usuall...
The 1992 public information campaign, Safe Farm, made farm safety messages available to a diverse and independent target audience of 104,000 full-time and parttime Iowa farm operators and their families. The print portion of the campaign reached 5.03 million Iowa newspaper subscribers. A series of public service announcements received at least 180 h of air time on more than 100 Iowa radio stati...
