Rapid Test Kit for N-P-K in Soil

Soil analysis is conducted to evaluate the availability of nitrogen (N), phosphorus (P), and potassium (K) nutrients for rapid soil-fertilizer management in economic crops—within just 5 minutes. The method involves analyzing soil using color-developing reagents that are specific to each form of N, P, and K. Results are compared with a standardized color chart, ensuring accuracy and reliability. For more information, please contact Assoc. Prof. Natthaphol Chittamart, Department of Soil Science, Faculty of Agriculture, Kasetsart University. Tel: 0-2942-8104-5, 08-8068-6188 Line ID: @SoilKuNPK
