Ion-selective electrodes for simultaneous real-time analysis for soil macronutrients
(University of Missouri--Columbia, 2006)
, and of cobalt rod-based phosphate ISEs were satisfactory for measuring N, P, and K ions over typical ranges of soil concentrations. The nitrate ISEs, when used in conjunction with the Kelowna extractant (0.25M CH₃COOH + 0.015M NH₄F), provided soil NO₃-N values...
