- The productivity of a stand is determined by where it grows, where it stands. A growing place or also referred to as a site is a place or area that supports the growth of a stand. According to Yamani, "Good and fertile soil is a soil that is able to provide balanced nutrients and in accordance with the needs of plants which can then be absorbed by plants. This situation can be seen from the productivity of the land by analyzing the concentration of nutrients contained in the soil and the leaves. "(Yamani, 2007). The increasing demand for teak wood is needed improvement, one of which is improving soil fertility by knowing the status of soil nutrients and plants. Determination of actions to improve soil fertility is by knowing the status of nutrients. Diagnosis of nutrient status can be done such as by analyzing soil and plants. Julianti further explained that "The results of several studies that have been carried out show that the analysis using the DRIS method is better able to see the nutrient sequence that most limits production (can determine the order of nutrient needs of plants and nutrient balance of plants), more effective in correcting nutrient deficiencies at the age of plants. young, and can explain the response of plants. "(Juliati, 2010). The purpose of this study is to analyze the status of nutrient sites on JPP (KU I) plant forest vegetation and determine nutrient balance in JPP plants and fertilization recommendations with the DRIS (Diagnosis and Recommendation Integrated System). This research was carried out in the 12G plot of RPH Rejosari BKPH Sengguruh KPH Malang, Perhutani Public Corporation, East Java in March 2018. As for the analysis of soil and plant samples, it was carried out at the Balitkabi in March-May 2018. which is done randomly, both composite and whole. Whereas for leaf sampling, it is by dividing the characteristics of the leaves classified as good and bad growth types. The results of the study obtained balanced nutrient ratio status on teak plus Perhutani (JPP) vegetation on KU I namely N / P 5.1-7.1; N / K 0,893-1,146; N / Ca 0.49-0.65; N / Mg 2.37-4.53; P / K 0,516-0,184; P / Ca 0,086-0,103; P / Mg 0.393-0.766; K / Ca 0,509-0,618; K / P 5,393-6,526; K / Mg 2,313-4,406; Ca / Mg 4,343-7,516. Based on the DRIS index shows that N and P nutrients are deficient in nutrients, while the nutrients Ca and Mg experience excess nutrients and P nutrients are declared balanced.
