Resumen
The uncontrolled accumulation of livestock or urban waste may threaten the environment. Although the use of manure or biosolids as an organic amendment improves soil physical, chemical, and biological properties, it may introduce certain trace elements (ET) into soils. Due to the fact that some soil properties may be modified in depth with the application of waste of biological origin, the objective of this work was to study the vertical variation of pH, electrical conductivity, and organic and inorganic carbon content dissolved in a disturbed soil of sandy texture superficially amended with cow manure, biosolids and biosolids plus ash. Soil columns were used. The three amendments originated a significant increase in pH and EC in the superficial layer (0-1.7 cm) compared to control. The concentration of dissolved organic carbon (COD) was significantly higher (22-72%) in the upper layer of the amended soil columns compared to control. Manure treatments presented a significantly higher COD concentration in all layers compared to biosolids or biosolids plus ash treatments, suggesting that manure’s organic matter presented a higher degree of mineralization than the corresponding to the other two amendments
