@jebba I am familiar with them & have not used them. They can be effective, though I'm curious to know how it failed for you. As far as techniques for decomposing organic ingredients there are a host of ways, including #biodigesters, various ferments, sheet #composting (a favorite), #vermicompost, etc. In my thin sand "soils", #biochar does some heavy lifting. Also fond of pits for ALL paper / cardboard to feed worms, pill bugs, fungi.

The coolest thing at Larnach's Castle is the remains of the biodigester toilets they used to make gas for lighting etc. In the 1800s!

To do, cont. "2. HEALTHY #SOILS: crop rotation, #mulching, non-tilling, mycelia, compost teas, worm farming, animal poop, #biodigesters, reusing sediment in one area for another
3. #EARTHWORKS: swales, weirs/#CheckDams, small #ponds, #terracing, #KeyLine system, rocks, guiding downhill rainfall to seep into ground replenishing, #gabions, zuni waffle garden, water piano."
