Question

Mention three advantages of Conservation Tillage.

State any two advantages of conservation tillage.

Answer 1

1. Seedbed preparation
2. Increase in nutrient use efficiency
3. Weed control
4. Evaporation suppression
5. Water infiltration enhancement and improved water-retention capacity
6. Erosion control and maintains the productivity of upland soils by reducing erosion
7. Maintains a favourable soil temperature
   These benefits together result in increased and sustained crop yields.

Answer 2

Conservation tillage is a tillage method that leaves the previous year’s crop residue on fields before and after planting the next crop to reduce soil erosion and runoff.

Advantages of conservation tillage are:

1. It conserves water by reducing evaporation at the soil surface.
2. It conserves energy, time, fuel, and money by reducing the number of trips across the field. The cost of labour and machinery is also lessened.
3. Reducing potential air pollution from dust and diesel emissions.
4. Crop residue provides food and cover for wildlife.
5. Improves soil moisture by enhancing crop growth in dry periods or on droughty soils.
