Tillage is performed in arable cropping systems for
many reasons, including burial of crop residues and
weeds for disease and insect control; incorporation
of fertilizers and chemicals; creation of aggregates
and a condition of macroporosity for improved aeration,
water infiltration, and root growth; promotion
of soil drying and warming; and reduction of weed
competition at planting and lay-by (final cultivation
and spraying). Tillage depth can range from shallow
operations that barely scrape the surface 1-2 cm
(0.4-0.8 in.) of soil to deep operations that disturb
or even invert soil to depths of 0.5 m (1.6 ft). Subsoiling
(sometimes called ripping or deep chiseling)
is deep tillage using implements that produce little
or no inversion of the soil profile (see illus.).
