Abstract: This study aims to evaluate the nutrient status in the leaves of patchouli grown in Inceptisols soil in Aceh, Indonesia. The experiment utilized a randomized block design (RBD) with three replications. The study’s factor was applying fertilizer nutrients across eight treatments designed according to omission trials. The response to fertilizer nutrients was analyzed for N, P, K, Ca, and Mg concentrations in patchouli leaves 120 days after planting seedlings in pots. The patchouli seeds used were local varieties from Aceh (“Tapak Tuan”). Urea (45% N), triple phosphate/SP-36 (15.65% P), potassium chloride (49.8% K), calcium carbonate (40% Ca), magnesium oxide (60% Mg), and S elementary (88.9% S) are used as fertilizer sources of N, P, K, Ca, Mg, and S, respectively. The Inceptisols soil used was topsoil (0–20 cm). The experimental results showed that fertilizer nutrient stress treatment influenced the nutrient content of patchouli leaves in Inceptisols. The concentrations of N, P, K, and Ca in the patchouli leaves were below the adequacy threshold, showing deficiency symptoms. The critical nutrient levels in patchouli plants for macroelements N, P, K, Ca, Mg, and S were 4.5%, 0.35%, 1.2%, 2.5%, and 0.25%, respectively. Only Mg reached the nutrient adequacy standard in patchouli. The limiting nutrients for patchouli plants in Aceh Besar Inceptisols are N, P, K, and Ca. It is necessary to add nutrients of N, P, K, and C macro fertilizers to increase the growth and yield of patchouli in Aceh Besar, Indonesia.
