Nosaukums<p>This document describes a method to compare the quality of soils by determining the fatty acid composition of the leaves of plant species grown in these soils.</p> <p>This method does not make it possible to determine an optimal value of the Omega-3 index and, therefore, cannot be used to determine the intrinsic quality of a soil from a specific area (regarded as homogeneous). The method can only be used to compare the quality of soils between various areas.</p> <p>This method is applicable to:</p> <p>— soils from contaminated sites;</p> <p>— amended soils;</p> <p>— soils after remediation;</p> <p>? soil with waste products (e.g<i>.</i> slurry, manure, sludge or composts).</p> <p>Alternatively, the quality of soils can be assessed by determining the Omega-3 index of <i>Lactuca sativa</i> seedlings grown in these soils under controlled conditions (i.e. phytotronic chamber) and by comparing these values to those obtained from control soils (see Annex B).</p>
