This research aims to map the nutrient status of N, P, and K in wetland soils in Pamulihan District, Sumedang Regency. The study was conducted to determine fertilization recommendations for wetland soils, especially for paddy fields, according to the guidelines for using the Soil Test Kit (PUTS). The research was conducted from July 2024 to August 2024 in Pamulihan District. The research method involved collecting primary data through field surveys, determining the number and location of sample points using random sampling with ArcGIS 10.8, sampling at the designated points, and analyzing the chemical properties of dryland soils in Pamulihan District according to the guidelines for using the Soil Test Kit (PUTS). Geographic data were collected and analyzed using GIS technology to map the nutrient status of N, P, and K in wetland soils in Pamulihan District. The results of the nutrient status testing in wetland soils in Pamulihan District showed low nitrogen (N) status in 145.89 ha (63.35%), medium phosphorus (P) status in 155.40 ha (67.47%), and high potassium (K) status in 192.11 ha (83.41%) of the total wetland area sampled, according to the guidelines for using the Soil Test Kit (PUTS). These were mapped on a semi-detailed map with a scale of 1:50,000. Fertilization recommendations for nitrogen (N), phosphorus (P), and potassium (K) in wetland soils were prepared from the district level, village level, and sample point level according to the fertilization recommendations of the Soil Test Kit (PUTS). The conclusion of this research is that the nutrient status of wetland soils in Pamulihan District shows low nitrogen (N), medium phosphorus (P), and high potassium (K) status, mapped on a semi-detailed map with a scale of 1:50,000, and fertilization recommendations were prepared according to the guidelines for using the Soil Test Kit (PUTS).
