We investigate the impact of household use of labor-saving farm technologies on first-time out-migration after the household agriculture and consumption survey was conducted in 1996. Building on the labor substitution framework, we hypothesize that household use of labor-saving technologies (e.g., tractors, farm implements, chemical fertilizers, and pesticides) increases individual out-migratio...

PURPOSE This study used a randomized control design to evaluate the effectiveness of AgTeen, an in-home, family-based farm safety intervention, in decreasing extra riding on tractors by youth. Having children as extra riders on tractors has deep roots in farm culture, but it can result in serious injury or death. METHODS The study randomized 151 families into 3 groups: parent-led intervention...

Variations in sinkage and cone index are of crucial importance when planning fieldwork, and for determining the trafficability of farm machinery. Many studies have highlighted the link between higher values of these parameters and dramatic decreases in crop yield. Variations in the dry bulk density and cone index of clayey soil in Southern Spain were measured following each of five successive p...
