What is the primary goal of soil conservation in agriculture?
Maximising soil erosion
Depleting soil nutrients
Minimising soil loss and maintaining soil health
Promoting monoculture
Which of the following is an erosion control technique in agriculture?
Excessive ploughing
Deforestation
Cover cropping
Monocropping
Why is soil moisture conservation important in agriculture?
To promote waterlogging
To deplete groundwater resources
To ensure optimal plant growth and reduce water runoff
To encourage desertification
What is the primary objective of conservation tillage?
Maximising soil disturbance
Minimising soil erosion and preserving soil structure
Accelerating soil degradation
Eliminating all soil organisms
Which conservation tillage practice involves leaving crop residues on the soil surface?
No-till farming
Conventional tillage
Deep ploughing
Harrowing
How does cover cropping contribute to erosion control?
By increasing soil disturbance
By providing a protective cover to the soil
By promoting monoculture
By encouraging excessive ploughing
What is a potential benefit of soil moisture conservation for crop production?
Increased water runoff
Reduced irrigation needs
Enhanced soil compaction
Depletion of groundwater resources
Which erosion control technique involves planting vegetation along contours on sloping land?
Terracing
Mulching
Contour ploughing
Strip cropping
Why is conservation tillage considered environmentally friendly?
It maximises soil disturbance
It eliminates all soil organisms
It reduces fuel consumption and carbon emissions
It accelerates soil degradation
What is a potential drawback of excessive ploughing in agriculture?
Enhanced soil structure
Increased soil erosion
Improved water infiltration
Preservation of soil health
