I'm finding that one of the beauties of the Mediterranean climate is that it is possible to build a soil by the direct application of organic matter, which in a wetter climate breaks down too quickly (
biochar is a solution there). We heat with wood and also have sheep, which uses/processes a lot of the organic matter into
ash and manure/litter. But there is still a yearly quantity of prickly or poisonous prunings, dead stalks from this and that, and paper and
cardboard (though a lot of this I soak, roll up and tie, and dry out to burn) which needs something done with it....left lying around it is a fire hazard and rodent habitat. So I have three raised beds bordered with metal, with mesh underneath to keep gophers out (thus preventing rodents in general from getting in. I use these for
root veggies which otherwise would feed the gophers. Each year I dig out most of one bed and pile this soil onto the others, into wheelbarrows, etc. and then put the accumulated brush, etc. into the bottom of the nearly empty bed. It's a good place for
humanure compost too, provided the root veggies grown in it are for cooking only (like potatoes). Then I add other compostables like sheep and poultry litter, and pile some of the soil back in. This "cleans up" the
yard for the year....although a new brush pile will begin accumulating soon enough. The next year, another bed is on deck for digging out and re-filling. By the 3rd or 4th year when the rotation comes back, all the stuff is pretty much composted.....
