Raindrops hit exposed soil and displace soil particles
Deep channels called gullies are formed
Surface runoff detaches and transports soil particles
Which of the following is NOT an impact of excessive erosion on agricultural productivity?
Loss of organic matter
Exposure of nutrient-rich topsoil
Increased water infiltration in soil
Breakdown of soil structure
The presence of which clay mineral leads to high phosphorus fixing capacity in red soils?
Kaolinite
Montmorillonite
Vermiculite
All of above
How is sheet erosion caused?
By surface water runoff
By raindrop splash
By downward cutting of streams
By wind-blowing soil particles
