Plant growth-promoting endophytic bacteria can increase plant nutritional efficiency thus favouring its yield. With the purpose of evaluating the influence of 10 previously selected isolates of growth-promoting endophytic bacteria on the uptake, utilization and transport of nutrients by tomato plants, greenhouse experiments were installed. The hypocotyl was cut in order to apply the endophytic bacteria to tomato seedlings cultivar Santa Clara. Fifty five days after transplanting the upper portion of the cut seedlings, the plants were collected to determine the […]

The use of mechanistic models based on principles of solute transport may be of great utility to estimate, for example, the impact of eucalypt forest cultivation on the pools and fluxes of nutrient in soils. Among the parameters required by such models are the values of the ion absorption kinetics constants Vmax, Km and Cmin. Thus, the objective of this study was to determine the values of Vmax, Km and Cmin for K, Ca and Mg, as well as to […]
