Preparation of soil samples 土样制备 ការរៀបចំសំណាកដី
Sample preparation and storage depend on the type of samples and the desired analysis. It is best to always check with the laboratory technicians who will be doing the sample analysis to find out what is required in terms of sample processing, transport, and storage. Preparation of air-dried, less than 2 mm samples is standard for many nutrient analysis.
