Abstract

Compaction results from compressive forces applied to compressible soil by machinery wheels, combined with some tillage operations, particularly when the soil is moist to wet and most prone to deformation. Human and draft animal-pulled equipment may also cause soil compaction, but a huge gap exists on experimental data to ade- quately assess their impacts and, actually, animal traction is an option seen with increasing potential to contribute to sustainable agriculture, especially in (but not restricted to) mountain areas. This study was conducted to assess the impacts on soil compaction of tillage operated with motor tractor and draft animals. In a farm plot (Vale de Frades, NE Portugal) treatments were applied in sub-plots (30mx3m), consisting in a two-way tillage with tractor, pair of cows and pair of donkeys. Undisturbed soil samples (120) were taken before and after operation for bulk density, porosity and saturated hydraulic conductivity.Results of thisfirstexperiment, althoughseeminglypointing animal traction as a sustainablealternative to conventionalmotorizedoperations, are notyetconclusive, showingth- eneedforfuture experimental researchonthisissue.
