Not if the seeds don't survive at all unless they're buried. The video mentions dehydration and "being eaten" as some major reasons why seeds on the surface don't survive. Also, this seems to be an invention aimed at seeding/reforesting large amounts of land at once from airplanes. Using many more seeds than needed may be cost prohibitive for large areas. Shaving up a tree and making a billion of these tiny wooden thingies seems like it could be automated extremely well so they might be very cheap per unit.
