Contour cultivation, contour strip-cropping, mixed-cropping and tillage are examples of which of these terminologies? Correct Answer Mechanical and agronomic soil and water conservation

The correct answer is Mechanical and agronomic soil and water conservation.

Key Points

  • Agronomic conservation measures function by:
    • Reducing the impact of raindrops through interception and thus reducing soil erosion.
    • Increasing infiltration rates and thereby reducing surface runoff and soil erosion.
  • These measures can be applied together with physical or biological soil and water conservation measures.
  • In some systems, they may be more effective than structural measures.
  • It is the cheapest way of soil and water conservation.
  • The differences in erosion rates caused by different land-use practices on the same soil are much greater than the corresponding values from different soils under the same land use. 
  • Agronomic measures are often more difficult to implement compared with structural ones as they require a change in familiar practices.

Additional Information

  •  Integrated Pest and nutritional management
    • Integrated pest management is a broad-based approach that integrates practices for Organization defines IPM as the careful consideration of all available pest control techniques and subsequent integration of appropriate measures that minimize risks to human health and the environment.
    • The introduction and spread of invasive species can also be managed with Integrated Pest Management by reducing risks while maximizing benefits and reducing costs.
    • Entomologists and ecologists have urged the adoption of IPM pest control since the 1970s. IPM allows for safer pest control.
  • Watershed based management system
    • The word watershed introduce in 1920 was used for the water parting boundaries.
    • A Watershed is a land area that drains or contributes runoff to a common outlet.
    • A Watershed is defined as a geohydrological unit draining to a common point by a system of drains.
    • All lands on earth are part of one watershed or another.
  • Resource conserving technologies
    • Resource conserving technologies refers to those practices or technologies that enhance resources or input use efficiency such as new varieties that use nitrogen more efficiently, zero or reduced tillage practices that save water, etc, which may be considered as RTCs.
