Great idea Mark, thanks for all you do!
Diggin that grinder. Burn baby burn!!!!
Outstanding!👍
Excellent work. Some people argue against grinding them up to the size of sand grain thinking that they need biochar of different sizes don't understand that it's not easy to disperse the biochar in such a large quantity without heavy machinery which in turn, cost fuel to run. Grinding the char to this consistency allows earth worms to swallow the grains which serve two purposes simultaneously: dispersion of the char into the soil and innoculate the biochar inside the worms gut.
But different sized biochar acts as slow release, bigger particles taking longer to break and absorbing and holding the water longer than small sized particles. In short, you will need to disperse bio char more often the smaller you grind it. Both have their pros and cons.
@@kamalpreetsinghgill1396 Bigger particles don't hold water better than the smaller ones since biochar relies on the porous structure and electrical charge to hold onto the water molecules. In fact smaller particles will always have better water holding capacity because their smaller size increases the total surface area exposed to the soil. Larger particles are harder to disperse, any particles bigger than a grain of sand would be very difficult to be moved by water or animals especially small animals like earth worms.
Smaller fragments are desirable, but milling the char post-pyrolisis into such small fragments destroys most of the tubular structure of the wood. Ideally, the feedstock should be reduced to the target fragment size before pyrolisis (i.e. run the wood through a chipper before the burn).
@@macoppy6571 That is the ideal solution but I work mostly with sugarcane waste and straw so they are already crumbly after Pyrolysis. Indeed in most of the research papers I have read they work with saw dust and similar pre- shredded feed material, another reason for that is because most of the Pyrolysis machines have a rotating kiln design so they only work with pellets and powdered feed material.
It's Ron Swanson ! :D
Correct me if I’m wrong, but isn’t biochar and charcoal the same thing, biochar has just had nutrients and bacteria added for the use as a soil amendment?
I know it's hard to find the right replacement PTO cover, even such universal replacement kits can still be dangerous. one could make a large placed over plywood box, over it, yet then if it loosens up and it goes flying and thus more dangerous. needs to be some retired tecnitions running on donations sneaking on to farms and pimping out peoples PTO's. Well I tend to drill holes in golf balls and pacing them on rebar property markers anonymously, even after the safety engineer placed coloured survey tape on them, in thinking that no one ever slips and falls.
