dig-irnas-es-10261-673812016-02-17T13:45:54Z Successive applications of composted municipal refuse. II. Effect of selected soil characteristics Murillo Carpio, José Manuel Hernández Reina, José Manuel Barroso Paz, Mercedes Gómez Asencio, E. Municipal refuse Soil characteristics 10 pages, 3 figures, 3 tables, 16 references. The effects of composted municipal refuse from the city of Seville on selected soil chemical properties and heavy metal accumulation in a calcic, loam soil were studied. Compost was annually added for six years to a series of cropped plots at two rates that generated a total amount of compost equivalent to 150 and 400 t ha-1 respectively. Organic matter (O.M.), N, P and CEC values showed significant increases at the surface (0-10 cm) and deeper (12-22 cm) soil layers, thus corroborating the existence of an effective nutrient migration process downwards in the soil. The K potential, measured by the equilibrium activity ratio aK/(aCa +aMg)1/2, ARk, the exchangeable Na and the soil pH did not undergo any significant changes. Despite its enhancement of soil fertility, compost also caused an increase in the total and DTPA extractable fractions for all the heavy metals analysed in the surface soil and deeper (12-22 cm). The exchangeable, bound to carbonates, Fe-Mn oxides and organic matter fractions also showed significant increases for most of the heavy metals analysed, thus indicating a significant degree of soil pollution.
