Se describen los resultados obtenidos durante 1981 por la seccion de Microbiologia del Suelo del Programa de Pastos Tropicales del CIAT, cuyos objetivos especificos son: 1) seleccionar leguminosas forrajeras promisorias que no requieren inoculacion; 2) seleccionar cepas de Rhizobium para legumino
Chemical analysis and missing element trials with Sorghum vulgare L. showed that three Panamanian soils, representative of three great soil groups, were deficient in both nitrogen (N) and phosphorus (P).
This paper reviews the experimental basis for the lectin-recognition hypothesis and considers ways in which the host/Rhizobium interaction might be manipulated to enhance the benefits of symbiotic nitrogen fixation in the tropics.
Biological nitrogen (N2) fixation in both free-living and symbiotic organisms is an energy-requiring process dependent upon a supply of carbon and energy.
