The results showed soil nutrient status of N in CorePlant Gambir Garden Pakpak Bharat District. is likely to increase in the valley compared to the topof the hill and hillside. As for the value of pH and P are highly the same, while the value of K, Caand Mg rate tends to decrease.Keyword: land position, soil nutrients, gambir (Uncaria gambir Roxb.)
