Soil problems and their management: soil erosion, waterlogging, salinisation, structural deterioration
Human farming practices can damage soil in four main ways. Each type of damage reduces the land's ability to grow food, but farmers and governments can manage or reverse the harm.
Real World
In Pakistan's Indus Valley, decades of poorly drained irrigation have caused widespread salinisation, rendering over 6 million hectares of formerly productive farmland too salt-damaged to grow crops.
Exam Focus
For 'suggest' questions, state the management strategy, explain the mechanism by which it works, and link back to the specific soil problem named.
