Question

Conservation tillage is in
(a) Terrace tillage
(b) Reduced tillage
(c) No-tillage
(d) Both b and c

Answer 1

Hint: The techniques which prevent the soil erosion and retention of organic matter in the soil and increase the ability of soil to retain water without disturbing the soil or with minimal disturbance of soil

Complete step by step answer:
The generic term which is used to describe tillage systems that have the potential to conserve water and soil that is reduced due to agricultural preparations of soil is called conservation tillage. It is a tillage system that creates a suitable soil environment by a reduction in the intensity of tillage, and retention of plant residues for the production of crops and conservation of soil. In this conservation tillage, there is a reduction in tillage or no-tillage is used.
So, the correct answer is ‘both (b) and (c)’.

Additional information:
- Preparation of soil by agricultural methods such as digging, stirring, and overturning is called tillage
- Reduction in the intensity of tillage by conserving water and soil is called conservational tillage
- Generally, there are four types of conservational tillage namely mulch tillage, ridge tillage, zone tillage, and no- tillage.
- The main forms of conservation tillage are direct drilling which is called zero tillage, reduced tillage, and minimum tillage.
- Conservational tillage provides several benefits such as soil conservation, reduction in soil erosion, retention of soil organic matter, and improvement of soil quality on the surface.
- Another important advantage of conservational tillage is the reduction of carbon dioxide in the atmosphere by reducing fossil fuel use by reducing the tractor passes and other types of equipment

Note:
- In no-tillage type, the plants are grown repeatedly year after year without disturbing the soil which helps in increases the amount of water that infiltrates into the soil, the retention of organic matter in the soil, and retention of cycling of nutrients
- In the reduced tillage technique, there is minimal disturbance of soil and crop residue to remain on the soil instead of throwing away.
