Soil Analysis Using Mehlich 3 Extractant Technique for Sample Preparation

The Mehlich 3 extractant technique has been used in the determination of macro and micronutrients in soils and also for the agrochemical testing of agricultural soil in the Czech Republic since 1999. This application note describes how the Advanced Microlab Diluter was used for sample preparation of the soil extracts. The semi-automated dispensing capabilities can be used for accurate and precise dilutions of the extracts for determination of calcium, magnesium and phosphorous.
