| La existencia de una racionalidad ecológica implícita en el manejo de los recursos naturales em agricultores tradicionales, ha permitido la sustentabilidad de los agroecosistemas. Comprender la racionalidad ecológica en agricultores con características diferentes a la agricultura tradicional, podría contribuir a avanzar hacia una agricultura sustentable. Sin embargo, esto no es sencillo debido a la propia complejidad del término y la ausencia de una metodología que permita abordarla. En este contexto, se propone y valida una metodología para abordar la racionalidad ecológica en tres grupos de agricultores hortícolas del partido de La Plata, Argentina. La propuesta consta de ocho pasos: 1) definición del marco conceptual, 2) planteo de hipótesis, 3)... |

| Cultivated and associated plant diversity, were compared (the last at 3 scales: alpha, beta and gamma), in 2 farms under conventional and organic management in La Plata. The relevé method was used for associated species recording in spring and summer. At farm level we assessed total spontaneous specific richness (γ diversity), genus and family richness. Richness – species total per crop- was used as index of α diversity. We also calculated the median richness per crop sample unit. A randomization method was used to assess the degree for which differences between the observed and expected median richness per crop in a management style are attributable to chance. β diversity values were compared to a random framework, separately for each farm.
