I have probably a trash barrel worth of charcoal left over from burning brush. I've been reading up on bio char, and it seems like it may be beneficial to the lawn. Is anyone making use of it by adding it to lawns and gardens? The soil over the new septic field needs amending, and this is where I was thinking of dispersing it. The grass has not come in thick yet, so I figure if I broadcast out and run it over with the lawn tractor, it should pulverize nicely. I can run the dethatcher over it to mix it in to the topsoil. Any ideas would be great.
I don't think there would be any isue in spreading it thru your lawn. Would be much like ashes from a wood or pellet stove. Don't put it next to acid loving plants, or where you plan to plant seedlings. Depends on how hard teh charcoal is whether it would be okay to use your lawn tractor to pulverize - it may take a toll on your blade.
I put it under fruit trees around here. Acidic loving plants like it. Peppers and Tomatoes. Putting it near the bottom might do the job and leave a buffer of soil between the pot or if you’re digging a hole for a well established plant.
I raked it into piles. The finer charcoal got scooped up and mixed with loam and peat moss to fill in spots in the front yard and cover grass seed. The rest I'll put through the small shredder and mix with leaves. Some will get mowed right in the immediate area as the soil needs ammending.
