Tertiary Land Preparation
What is the purpose of tertiary land preparation?
- Lowers the porosity and permeability of soil which destroys the soil structure.
- Forms a soil plow pan.
- Reduces loss of water from the soil through percolation.
What is the perfect timing?
- One day before sowing or planting.
What are the techniques to be used?
- Soil is flooded and then the tillage is performed (known as puddling).
- Several rounds of puddling is performed to mix fertilizer well.
- Then the soil is leveled well, to develop a good seedbed that is well suited for plant growth.
What are the important factors that need special attention?
- Puddling supports retention of water in the field for a considerable time
- Levelling ensures a healthy seedbed which provide uniform conditions to the crop.
