The evaluation of the amount of total and soluble P in surface waters is insufficient to diagnose their pollution potential. This study aimed to evaluate the P fractions and soil properties related to P release from eroded sediments of landscape units with different pressure levels of anthropogenic activity. Water + sediments were sampled in two landscape units of a sub-watershed of the small watershed Arroio Lino, in Agudo, RS, Brazil. The following properties were evaluated: pH, sediment concentration, total organic […]
