About article:
Organic hydromulches can be an interesting alternative for weed control in perennial crops, but can also
reduce soil water evaporation. To examine the effect of a hydromulch layer on soil water content in dry conditions
laboratory experiments were conducted at constant 25°C, 40% air RH. Both for small soil containers with a short time
course and for larger soil columns (with two sensors at depths of 6 cm and 11 cm) with a longer time course, the
presence and also the thickness of hydromulch were significant factors for the temporal evolution of soil water content.
Two distinct stages of the evaporation process, the first or initial stage and the last or final stage, were identified,
analysed and compared for these experiments. General linear models performed on the soil water content temporal
evolutions showed significant differences for the first and last stages at the top and bottom of the soil columns with and
without hydromulch. Hydromulch application delayed the evaporation process in comparison with the control.
Moreover, the hydromulch layer, which was tested for mechanical resistance to punching, offered enough resistance to
prevent its perforation by the sprouts of weed rhizomes.
