Abstract

 

Soil is the
most precious gift of God to mankind and its proper management is a key to
sustainable crop production and other life existence on this planet earth. In
arable crops production soil tillage is usually noted for having greatest
requirement for energy and labour consumption. Thus one of the important soil
management is the proper amount and type of tillage system in use by the
farmer, because the potential for erosion either by water or wind of a specific
soil type depends largely on the number and types of tillage operations. Any
method adopted must ensure the long – term productivity of soil,
environmentally friendly and profitable. Tillage operations improve chemical,
biochemical, biological, physical and hydro-physical properties of soils and these
consequently increase soil water conservation and yield of crops. Surface
sealing and roughness, crusting, hardpan and soil compaction reduce drastically
with proper tillage operations of which will increase soil water storage and
availability to crops. This paper reviewed various terms used for soil tillage
its potentials and draw back in agricultural sustainability.

 

Keywords: Aggregation, crop yield,
