These images explore the unique agricultural practices of Lanzarote, where farmers rely on picon. The volcanic ash that is mined all over the island surface is being used to cultivate their fields. The series follows the journey of picon from extraction over distribution, to application and use, documenting its crucial role in local farming. Picon, a porous volcanic material, helps retain moisture and regulate soil temperature in the island’s arid climate. 

However, it does not replace natural soil; instead, it acts as a protective layer that must be carefully maintained. Farmers must take great care to avoid mixing picon with the underlying soil, as this could disrupt its beneficial properties. The project also highlights the agricultural cycle, from the treated fields to the local farmers' markets, where the island’s harvest is sold. Additionally, it examines the increased water needs of crops despite the water-retaining properties of picon, revealing the delicate balance between tradition, nature, and sustainability in Lanzarote’s farming landscape. Although picon is mined in many places all over the island, and every plant needs it to become fertile it is a dying industry. 

Since the picon never runs out of its protective and retaining characteristics if not mixed with the soil itself the industries days are counting down. The time will come where all the fertile soil will be covered with picon and no more is needed. Latest when the whole island resembles a black rock and white cornered shells.
