Determination of Available and Slow-release Potassium in Tobacco Field Soil with Flow Autoanalyzer

Abstract

Abstract

The available potassium(AP) and slow-release potassium(SRP) in tobacco field soil were determined with a flow autoanalyzer.The results indicated that the RSD and recovery of AP and SRP were ≤1.11% and 94.9%-102.6% and ≤ 2.55% and 95.2%-103.1%, respectively.The flow autoanalyzer was suitable for fast determination of AP and SRP in tobacco field soil.
