Maintenance of soil physical health at its optimum
level is essential for sustainable crop production and
rational use of natural resources without jeopardizing
their quality. The ongoing conventional tillage practices
for crop production using intensive ploughing
and removal of crop residue from the field have
resulted in an increase in surface crusting, soil
compaction, soil erosion, decrease in water infiltration
and ultimately aggravation of the overall soil physical
health deterioration. In recent years, many agricultural
scientists across the world have recommended
conservation agriculture as a solution to overcome the
adverse effects of conventional tillage practices on soil
physical health. Conservation agriculture is mainly an
integration of three crop management practices, viz.
minimum or no-tillage, permanent retention of crop
residue and crop rotation. The present data indicates
that conservation agriculture can improve soil physical
properties and associated processes especially, soil
water infiltration and storage, soil aeration, soil structure
and soil porosity. It reduces soil erosion, soil
compaction and crusting, and optimizes the soil temperatures
for successful crop production. This article
reviews the role of conservation agriculture in
improving soil physical health and its associated processes
