Fertilization of its soils was done through generations of farmers by gathering sargassum seaweed from the ocean, to fertilize the infertile soil. The parish is home to Póvoa de Varzim Horticulture Association - the Horpozim.
This refers to a long-standing agricultural tradition of using sargassum seaweed as fertilizer in this specific location. The Horpozim plays a significant role in maintaining this practice.
