Abstract

ANALYSIS OF NUTRIENT CONTENT OF TOTAL NITROGEN ON PADDY FIELD OF TAPADAKA VILLAGE OF SOUTHEASTERN DUMOGA DISTRICT OF BOLAANG MONGONDOUW REGENCY

Research was aimed to analyze the content of Nitrogen on paddy field area of Tapadaka Village of Southeastern Dumoga District of Bolaang Mongondouw Regency. This place was conducted for soil sampling. Soil analysis was in the Laboratory of Ecophysiology of BALIT PALMA, Mapanget Village, Talawaan District, North Minahasa Regency, North Sulawesi Province. The research was conducted by using the method of Survey with composite-sampling soils in technically (whether systematic, or random) for two months. Each composite sampling soil has taken in one area for three points of different plots then mixed them into one plastic bag. There were nine composite samples, i.e. in codes of P1A, P2A, P3A, P1B, P2B, P3B, P1C, P2C, and P3C. The soils samples were both analyzed directly in field by using Paddy field Soil Test Device and kjedahl Method in laboratory. Results of this study were analyzed that nutrient content of total Nitrogen by using Paddy field Soil Test Device was categorized in low, and the total Nitrogen for all samples were about 0.05% - 0.25% in criteria of very low to moderate.
