Sampling and analytical errors in the estimation of copper, cadmium, zinc and lead in soils locations
Aims

To establish soil sampling and analysis protocols for micronutrients.

Key messages
  • The sources of variation which contribute to errors associated with the assessment of soil zinc and copper were established.
  • Variation between soil cores greatly exceeded variation between chemical determinations.
  • Hence for a given investment of resources, errors can be more effectively reduced by increasing the number of cores per bulk sample than by increasing the analytical replication.
