Yes, and in addition this increase in retention capacity is spectacular. In fact, I have three different stages in the vegetable garden (following the various extensions): the old vegetable garden of 35m2, it has been under hay and other MOs for a year and a half; first expansion, under MO for ten months; and then the ultimate expansion, because I had too many plants, under hay since the end of February. Between the old vegetable garden and the first extension there is a difference in fertility and water retention capacity, but it is much less important than I would have thought. And the third part on the other hand, for fertility it is better what I thought, but question of water retention, well it is not completely zero of course, because covered, but it is very quickly very dry. I draw one conclusion above all: cultivating under living cover (I thought to do it on small plots, which change location) here is not (yet?) The good option, too greedy in terms of watering, because that even if I have a good borehole, even if the water table is good (still, for how long), I try not to waste.
