In spain it's called jable (pronounced hablay) and it's volcanic and extremely porous, in the same way that biochar is. It can hold water and nutrients very well, and also, somehow it manages to stay in place on terraces rather than eroding away during flash floods. It can get a bit hard and compacted if it's been left in the sun unused for a few years, so needs disturbing a bit before planting seeds
Where in the world are you? Greece? I used to have a place south of Kalamata but I never came across this Jable type rock in that region.
Hi.Thank you for
the answer ,do you mean pumice stone? I am in North of Pelloponisos ,near Patras.Kalamata is in the southern part.
The rock i am crushing is lightweight ,but still is heavy compared to a pumice stone that is so porous.The thing is that due to continuous weeding,the soil on the main parts has
been degraded with no organic matter and it is exposed in the harsh sun.So i am putting this kind of rock to reflect the sun and i will throw clay seebals of cover crops when the first
autumn rains begin.
