5. Soil Resources
Soil resources play a crucial role in agriculture and the ecosystem, supporting plant growth through various types of soil, each with unique characteristics. Key soil types in India include alluvial, black, red, laterite, mountain, desert, and peaty soils, all of which influence the cultivation of different crops. Soil erosion poses significant threats to fertility and productivity, while conservation methods are essential for maintaining soil health and ecosystem balance.
