Pemetaan Status Hara Nitrogen Pada Lahan Sawah Intensif Di Kabupaten Sigi Provinsi Sulawesi Tengah

ABSTRACT
The purpose of this study was to identify and map the status of nitrogen nutrients in intensive rice fields in Sigi Regency, Central Sulawesi Province. Determination of the sampling location using the (Global Position System). Soil analysis was carried out at the Laboratory of Soil Science, Faculty of Agriculture, University of Tadulako, carried out from June to December 2020. The results showed that the N-total status in paddy fields in Palolo District was classified as very low, ranging from 0,01% - 0,08% covering an area of 207,1 Ha or 91,20%. Gumbasa District is classified as very low, ranging from 0,01% - 0,07% covering an area of 331,20 Ha or 100%. and Sigi Biromaru District was classified as very low, ranging from 0,01% - 0,07% covering an area of 137,21 Ha or 100%.
Keywords: Mapping, N-total, and Intensive Rice Field.
