Abstract

Odell and Cowan's (1987) experimental study largely confirms and extends results obtained by Lewarch and O'Brien (1981) on the effects of tillage on artifact distributions in the plow zone. In contrast to earlier studies, however, they find no relation between artifact size and lateral-displacement distance. The lack of relation between these two variables may be a consequence of defects in experimental design and analysis and should be considered suspect until better controlled data are available.

Résumé

Résumé

El estudio experimental de Odell y Cowan (1987) confirma largamente y extiende los resultados obtenidos por Lewarch y O'Brien (1981) acerca de los efectos del arado en la distributión de artefactos encontrados en zonas de labranza. En contraste con estudios previos, sin embargo, ellos no hallan ninguna relación entre el tamaño del artefacto y la distancia de desplazamiento lateral. La falta de relación entre estas dos variables es una consecuencia de defectos en el diseño experimental y en el análisis, y debería ser considerada sospechosa hasta que se disponga de datos controlados más estrictamente.
