Good stuff however their is science to support better yeilds from other "furrow" shapes than that created by a double disc opener.i.e. an "inverted Tee" furrow or slot, reduced Hair pinning of straw,and no side wall compaction.
The 'inverted T' furrow shape resulting from the cross-slot has plenty of compaction issues, since the wings are smearing the soil to create that shape. It's a miniature sweep plow. This smearing/compaction just below (& above) the seed is a significant problem for no-till cropland w/ any soil moisture & clay content. The 'inverted T' has further problems with lack of a seed-firming mechanism at the seed's location (squashing from surface is undesirable).Regards,
@MHagny Is your comment an opinion or based on science? Could you please provide references for me to review any data . The Research at WSU (Pullman) and Massey Uni,(NZ) summarised in Publication “ No-till Seeding in Conservation Agriculture” ISBN 1-84593-116-5 and Field trials carried out by FAR (Foundation for Arable Research, NZ ) over the last 5 years , would suggest the issues you raise are not reflected in the yields.
