No Till Seeding Explained, excerpt #2.mp4

No sales pitches. The DVD is aimed at nurturing your understanding of the seed-installation process, and we have tried in the utmost to be truthful and objective, and to deliver highly useful insights and tips. We sincerely want no-tillers to succeed, whether or not they buy any hardware from Exapta.
Detailed narrative and visuals to guide you through everything from off-season overhauls of your planter & drill, to exact step-by-step adjustments of your seeder in the field. Actual footage of Matt Hagny excavating seeds in furrows (both planters and drills) and discussion of what good seed placement looks like, and why. Troubleshooting. Maintenance tips. Aftermarket upgrades. Seedling growth. Fertilizer placement. Agronomy. How uniform timing of emergence overshadows uniform spacing for yield influence. For highly effective no-till seeding, this video has it covered.

@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.

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,

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.
