-bulk density correlated with yield
While I do not have the bibliographic info in front of me, it
is my recollection that R.R. Bruce et al. (Southern Piedmont
Conservaton Research Center) have found that high residue no-till
systems which restore degraded soils by dramatically increasing
infiltration, moisture retention, soil C, aggregate stability... also
promote significicant yield increases.
Is anyone of aware if any studies that compare aggregate
stability for soils with uniform managment across different soil
