Area of CCS having manure injected into soil via liquid spreader
Land use Total CCS area
Absolute or % area of farm land in CCS
Absolute or % area of pasture land in CCS
Absolute or % area of crop land in CCS
Human population Total human population in CCS

aCCS = consolidated census subdivision. Area of CCS is in square kilometers; absolute = absolute squar
