Résumé
Nine physically and chemically different soil samples from five study sites in which agaves grew, or were grown, were investigated to evaluate the effects of soil physical and chemical properties on the growth habits of agaves. In five Arizona study sites, biomass data of seven agave species has been recorded for the past ten years. Agaves were grown experimentally in the greenhouse using two widely different soil types from the five sites to evaluate growth under controlled conditions. Influence of edaphic factors on agave growth for the study sites and greenhouse experiment was evaluated. The results show that the determinant primary factors were water availability and temperature. Soil texture, soil pH, soil CO2 concentration, nitrogen, and soluble salt concentration were placed as influential secondary factors for the growth of agave. The degree of influence of these soil factors depends highly upon the genetic characteristics of agave species
