Nutrient Status Of The Soil Layers Of Rice Fields In Taratara Satu District, West Tomohon District Tomohon City
Research in the field aims to determine the nutrient status condition in rice fields' soil layers. The things studied are N, P, K, C-organic, soil pH, and soil texture. The research is a survey method with a composite soil sampling technique at 0, 10, and 20 cm depth. Soil samples were taken at six different rice field points in the Taratara area. The nutrient status of N, P, K, and soil pH were analyzed using the Paddy Soil Test Kit (PUTS). C-organic using the Walkley and black method and for soil texture using the pipette method. The data from the analysis is then arranged in table form and explained descriptively. The research results from the six locations studied showed that: 1). N nutrient status is at low status; 2). P nutrient status is low, medium, and high; 3). K nutrient status is at medium and high status; 4). C – Organic nutrient status is at very low and low status and 5). Soil pH is slightly acidic and 6). Soil texture conditions are in the criteria of loam, silty loam, and silty clay loam. Keywords: Nutrient Status, Paddy Soil Layers.
