- Duration: 44:56
- Updated: 28 Mar 2015
Language: Hindi, Topics Covered:
1. Recap of previous lecture:
2. Soil formation: 5 factors affecting it: rock, climate, relief, biota and time.
3. Transportation in soil: capillary and leaching process
4. Types of leaching process
5. 3 chemical process in soil: capillary action, leaching and gleying
6. Soil Profile, Leaching and capillary in horizons
7. Soil erosion: meaning, factors responsible and implications.
8. Soil conservation techniques: structural and non-structural
9. Structural solution for soil conservation: slopes, Stone pitching and wire netting
10. Structural solution for soil conservation: coastal areas- Tetra-pods, groyne
11. Non-structural solutions for soil conservation: afforestation, slopes, agro-practice reforms, Strip farming, mulching, desert margins – transverse farming
12. Soil salinity: reasons, implications.
13. Structural solutions to combat soil salinity- washing, underground piping, canals and amendments.
