Organic wastes from different sources determine the variation of several soil physico-chemical parameters such as pH, heavy metal content, redox potential, complexing activity and degree of humification, what may affect the soil fertility in a positive or negative way. The organic fraction of low molecular weight is involved in ionic mobilization and humification processes, its presence is particularly important in soils with a low level of organic matter and micronutrients.
