Dr. Theodore Friedrich of the FAO explains the 3 Conservation Agriculture principles:
- Continuous minimum mechanical soil disturbance
- Permanent organic soil cover
- Diversification of species grown in rotation or association at the same time
He explains the implications of Conservation Agriculture for various aspects of conventional agriculture; particularly for seeding and planting, as well as with regards to tillage, mechanical and animal traction.
With regards to weed management, Friedrich introduces the viewer to some non-chemical options for weed control such as soil coverage of various means, which may be manual or aided by mechanical equipment
