The links below are my papers, I think, they will help you to decide about better biochar size.
Physical modification of biochar to expose the inner pores and their functional groups to enhance lead adsorption - RSC Advances (RSC Publishing) DOI:10.1039/C8RA06867D
Particle size and rate of biochar affected the phytoavailability of Cd and Pb by mustard plants grown in contaminated soils: International Journal of Phytoremediation: Vol 22, No 6 (tandfonline.com)

I have been using water and wood chipper to crush biochar. Most of it comes out as dust size (slurry of dust size particles)Is there any data from studies on best crushed size biochar for types of soils for fertility and life for sequestering purpose ?
I read on a facebook posting that biochar dust in sandy soils will wash away into groundwater.
Also, might dust not have the benificial micro pores ?
