Biochar from the burn... when straw or leaves burn cool and quick it leaves behind a lot of charcoal. I’d guess where it burns fastest it’s up to 90% charcoal left behind and just 10% ash. The ash won’t hurt either because the soil here is acidic and ash is mostly calcium and potassium and sweetens the soil.
Generally, slash and burn agriculture on acidic soil might work well for one year but beyond that it’s terribly unsustainable and hard on natural resources. Adding old hay or leaves to a garden is reasonably sustainable though right?... so maybe the use of ‘slash and burn’ here is different / not all bad...???
Again, I would not recommend adding uncomposted lawn clippings because this will feed legions of pests rather than the plants. I think browns like straw/old hay and dead leaves is safe even when not composted because there is not enough energy or nutrition in them to directly feed the worst garden invertebrates (bug pests).
