tRiparian buffer zones have the potential to capture chemical contaminants and to mitigate detrimentalside-effects in aquatic ecosystems derived from excess fertilizers used in agro-food production. No-tillfarming systems are well known agricultural practices and are widely used in temperate areas. In thatregard, different settings and widths of riparian buffer zones (12, 24, 36, 48 and 60 m) with woody veg-etation, shrubs or grasses were assessed. The methodology was comprised of the evaluation of a largenumber of experimental sites and the sampling was conducted after the first rain period and respectivefertilizer applications. The results point to the fact that effectiveness is largely controlled by buffer zonewidth and vegetation type. Indeed, buffer zones with 60 m width composed of woody soils were moreeffective in phosphorus (99.9%) and nitrogen (99.9%) removal when compared to shrub (66.4% and 83.9%,respectively) or grass vegetation (52.9% and 61.6%, respectively) areas. Woody vegetation has deep roo-ting systems and woody soils have a higher content of organic matter when compared to grass and shrubsareas. |
