✦ Synopsis
Results from a 3-year experiment carried out to detect the consequences of using municipal solid waste compost (MSW) in agriculture are reported. To assess the persistence of its effects in time, the compost was spread only in the first year. In particular, the effect of the compost upon top soil compaction caused by a wheeled-tractor equipped with traditional and low pressure tyres was considered. It was found that soil treated with compost was less compactable than normal soil and that this effect lasted into the third year. However, the lower bulk density in undisturbed soil resulting from the compost diminishes with time. The lower compaction achieved using low-pressure tyres occurred only after the first pass of the tractor; after the second pass, compaction was practically the same as with conventional tyres. Crop yield was reduced by the application of compost and this decrease arose in the first year. No significant difference in yield resulted from the use of the low-pressure tyres, apart from some trend towards higher production in the second and third year in less compacted soil.
