Governments intervene in the agricultural sector through policies that both support and shape agricultural production. This leads to two important outcomes. First, agriculture specific programmes intended to increase the welfare of farmers can become capitalised into asset values. Second, many...

The method described in this Test Guideline is based on soil column chromatography in disturbed soil. Two types of experiments are performed to determine (i) the leaching potential of the test substance, and (ii) the leaching potential of transformation products in soils under controlled...

This Test Guideline describes a laboratory test method designed to investigate long term potential effects of a single exposure of agrochemicals/non agrochemicals on carbon transformation activity of soil microorganisms. A minimum of two test concentrations are recommended for agrochemicals...

This Test Guideline is designed for assessing the effects of chemicals on the reproduction of collembolans in soil. The parthenogenetic Folsomia candida is the recommended species for use, but an alternative species such as sexually reproducing Folsomia fimetaria could also be used if they meet...

The method described in this Test Guideline is designed for the evaluation of the mineralisation rate of a 14C-labelled compound in soil. The method is applicable to volatile or non-volatile, soluble or insoluble compounds which are not inhibitory to micro-organisms. The basic test consists on...

This Test Guideline describes a laboratory test method designed to investigate the long-term effects of chemicals, after a single exposure, on nitrogen transformation activity of soil microorganisms. Sieved soil is amended with powdered plant meal and either treated with the test substance or...
