Concept
Agriculture and industry are the backbone of an economy. India's agriculture depends heavily on the monsoon, while industries are located near raw materials, power and markets.
Knowing crop–region and industry–location links is useful.
Key Points & Formulas
- Kharif crops (sown with the monsoon): rice, maize, cotton.
- Rabi crops (winter): wheat, gram, mustard.
- Black soil suits cotton; alluvial soil suits rice and wheat.
- Iron & steel industries locate near coal and iron ore (e.g., Jamshedpur).
Worked Example
Q. Why is black soil ideal for cotton cultivation?
Black (regur) soil is rich in clay and retains moisture well.
Cotton needs moisture-retentive soil and a warm climate.
Hence black soil is also called black cotton soil.
