Los factores ms importantes que determinan la biodisponibilidad de nutrientes para las plantas son los fenmenos que regulan su concentracin en la solucin de suelo y los procesos de transporte hacia las races. Por ello, en esta obra se tratan los procesos de liberacin de fsforo, potasio, calcio y magnesio a la solucin de suelo, la cantidad de estos macronutrientes que es aportada por flujo difusional y se establecen los coeficientes de difusin para las formas inicas analizadas. Adems, se analiza el efecto de la intensidad de cultivo sobre propiedades fsicas, qumicas y mineralgicas y sobre el flujo difusional y los coeficientes de difusin en parcelas con distinta historia agrcola. Se desarrolla el estudio de los procesos de difusin usando columnas de suelo con distintas geometras experimentales, empleando intercambiadores inicos sintticos para simular la accin de las races absorbentes. Se presenta evidencia sobre el importante efecto del factor de impedancia que da cuenta de la tortuosidad y continuidad de la red de poros sobre el flujo difusional de los nutrientes analizados.
