SP FAQ - Hairpinning and Shading by Residues

Q.
What is the disadvantage of seed becoming lodged in residue (a hairpin) that is pushed down into a no-tilled slot in a wet soil?

Q.
Does this not happen with Cross Slot openers too?

Q.
Are there any circumstances in which seed burn will not occur when residue is pushed into the slot of other openers?

Q.
Does that mean that in optimal soil conditions one would not expect to see major differences between Cross Slot and other no-tillage openers?

Q.
Do surface residues cool the soil down?

Q.
Does the shading effect in spring create problems for Cross Slot, which replaces the residues over the slot?
