In the Onattukara wetland paddy fields special agricultural zone, this study aims to identify various topographic aspects and the properties of macronutrients in soil samples. The precise locations of multiple soil sampling spots located in various Onattukara blocks were identified using the Global Positioning System (GPS). In soil samples collected from several locations in the paddy fields region, the macro (N, P, K) nutrients were examined. 16 soil samples were collected, and their locations were determined using GPS technology in this field's Onattukara special agricultural wetland zone. Nearly all soil samples contained low levels of nitrogen and phosphorus, although potassium availability was found to be moderate. According to the data, soils are deficient in N, P, and K, making it necessary to add more fertiliser and manures in order to cultivate them and encourage healthy growth.
