| Abstract | Incorporation of sulphur rich crucifer tissues into soil is known to suppress a variety of soil-borne plant pathogens and pests. Although the 'biofumigant' effect has been attributed to release of toxic isothiocyanates (ITC) during crucifer tissue decomposition, little is known of the dynamics of formation of these compounds, or other non-glucosinolate derived toxic volatile S compounds, during the decomposition process. We compared concentrations of these two groups of compounds during decompos olate derived volatile S-containing compounds carbon-disulphide, dimethyl-disulphide, dimethyl-sulphide and methanethiol were the dominant headspace components, with maximum concentrations reaching 88, 39, 406 and 992 nmol g-1 dw leaf incorporated, respectively, in sandy-loam and 152, 22, 119 and 473 nmol g-1 dw leaf added in clay-loam. Only small quantities of glucosinolate hydrolysis products were detected. Maximum headspace concentrations of 2-propenyl-ITC were 12 and 2 nmol g |
