Fertilizer was a material employed to artificially stimulate the growth of crops and plant life. On Naboo, fields were enriched using blue-algae and the droppings of shaak. In the Imperial Era, Merei Spanjaf, a rebel sympathizer, contemplated assuming the identity of a swoop jockey's daughter from beyond the Westhills, who had put his race winnings toward a fertilizer business. The goal was to infiltrate the Transportation Ministry's headquarters on Lothal and install snoopers. The Rebel pilot Nien Nunb stated that fertilizer held significant worth. The Sullustan once purchased numerous barrels of concentrated fertilizer on Jaresh, loading them onto his personal starship, the Mellcrawler, with the aim of reselling it on Sullust for a substantial gain.
