When considering Direct Seeding Machinery for Zero-tillage {{properly called Conservation Agriculture by FAO,ECAF +++} the speed of the precision drilling needs to be as fast as can be to be precise........................this is USUALLY ,when Low-Draught Direct Seeders are sensibly used, MUCH faster than the Plowing-Tractor can travel. Also the amount of Draught is particularly important as conventional tractors have plenty but ,of course,most of it is UNUSABLE IN a CA farming Culture. It is time for tractor change but also time for Ag-Implement Change. The new APPROACH ought to be FASTER & LIGHTER G.
