Abstract :
Macro-nutrients are essential nutrients that every vegetation needs in large quantities. The level of stand productivity is also related to the quantity and quality of nutrients on the land. On the lan there are silviculture actions that are used repeatedly so that macro-nutrients have the potential to decrease. The purpose of this study was to assess to balance of each macronutrient (N, P, K, Ca and Mg). Data analysis used the DRIS (Diagnosis Recommendation Intregreated System) method with Minitab 16 as a tool. Samples taken included selected stand leaves and stand soil samples analyzed at Balai Penelitian Tanaman Aneka Kacang dan Umbi (BALITKABI) Malang. Lead samples used were 12 leaves. The soil samples used were composite soil samples. The results showed the final result of the N nutrient of 0, P nutrient of -0.23, K nutrient of 0.19, Ca nutrient of 0.09, and Mg nutrient of 0. It can be concluded that plot experienced an imbalance or deficiency of P nutrients and bad abundant nutrients in K. The deficiency of P nutrient is due to the absorption of P nutrients with metal element (Fe), which affect the lack of P-available nutrients. Based on the results of this study, its is suggested that there is a need to increase the intake of soil organic matter in nutrient P trough fertilization either from compost, manure or P fertilizer which is able to release P sequatration soil pH.
