This is presentation on topic of Conservation Tillage, it gives You information about conservation tillage, types of conservation tillage, Practices used in conservation tillage. It enhanced Your knowledge about conservation tillage.
2. ο
Any tillage or planting system in which at least 30
percent of the soil surface is covered by plant residue
after planting , To
Reduce water and wind erosion .
It optimize conservation of soil and water resources.
Conservation Tillage
3. ο
ο There are are five types :
ο 1) No tillage
ο 2) Mulch tillage
ο 3) Strip or Zonal tillage
ο 4) Ridge till
ο 5) reduced till
Types of Conservation
Tillage System
4. ο
ο Planting crops in previously unprepared soil by
opening a narrow slot, trench or band
ο Sufficient depth and width to obtain proper seed
coverage.
ο Herbicides used for weed management .
ο Effective conservation practice for reducing soil
erosion and improving water quality.
ο Minimum tractor power used .
No Tillage /Zero Tillage
5. οο This is done by heavy implements .
ο Sow seed and applied fertilizer at the same time .
ο Zero tillage have increased yields in wet areas.
No Tillage /Zero Tillage
6. ο
ο It is also called stubble mulch forming .
ο Causing least soil disturbance .
ο Leave maximum crop residues on soil surface .
ο A chisel plough used for break hard pan of soil .
Mulch Tillage System
7. ο
ο Protection of soil against raindrop impact
ο Improved infiltration capacity .
ο Mulch stability depends on rate of residue
decomposition .
ο Climate and soil properties .
ο Relief and rainfall characteristics .
Benefits
8. ο
ο The seedbed is divided into a seedling zone and a
soil management zone .
ο 5-10 cm wide tilled the soil for germination and
seedling establishment .
ο The inter row zone left and protected by mulch.
ο Strip tillage achieved by chiseling in row zone.
Strip Tillage System
9. ο
ο One third of the soil surface is tilled at planting with
sweeps or row cleaner .
ο Planting of row crops is done on performed
cultivated ridges .
ο Weeds are controlled by herbicides .
ο Sometimes ridges goes on to six seasons .
ο Planting is done on ridges .
Ridge Till System
10. ο
ο It is used in dry areas for collects of runoff water .
ο It induce waterlogging in clay soils .
ο Ridges are 20-30 cm wide and 10-20 cm high .
ο It increase the water holding capacity of soil.
ο Fertilizer and organic matter concentrated in ridges.
Benefits
11. ο
ο Any farming practice which involves less cultivation.
ο Minimize soil disturbance .
ο Weeds and grasses are controlled by herbicides .
ο There are three types of reduced tillage :
ο 1) reduced cultivation
ο 2) direct drilling
ο 3) minimum tillage
Reduced Tillage
12. ο
ο It involves grazing of crops stubble and weeds .
ο Followed by one cultivation .
ο Followed by contact herbicides .
Reduced Cultivation
13. ο
ο It involves no cultivation sowing directly into
undisturbed soil.
ο Stubbles removed by grazing .
ο Remaining stubbles is burnt after rainy days .
Direct Drilling
14. ο
ο It involves retention of stubbles and weeds
controlled by herbicides .
ο It involve one mechanical cultivation .
Minimum Tillage
