Palintest Soil Test Kits are designed to allow field testing of soil samples which should be comparable to standard laboratory methods.

All Palintest soil extraction methods are based on the method recommended in the UK by MAFF/ADAS ‘The Analysis of Agricultural Materials’ Reference book 427 where possible.
