Dependence on monsoon and natural fertility of the soil.
Explanation
Primitive Subsistence Agriculture is a traditional farming practice carried out on small patches of land. It utilizes primitive tools such as the hoe, dao, and digging sticks, relying primarily on family or community labour. The primary objective is to sustain the farmer's family rather than generating surplus for trade.
Detailed Analysis:
- Use of chemical fertilisers. is incorrect: This system does not utilize modern agricultural inputs such as chemical fertilizers, pesticides, or high-yielding variety seeds. Soil fertility is maintained through natural processes, often involving shifting cultivation (slash and burn).
- Dependence on monsoon and natural fertility of the soil. is correct: The farming system is entirely rain-fed, depending heavily on the monsoon for irrigation. Furthermore, productivity relies on the natural fertility of the soil without the addition of artificial nutrients.
- Production for international markets. is incorrect: Production is geared towards self-consumption (subsistence). It is not designed for trade, let alone international markets, which is a characteristic of commercial or plantation farming.
- Large scale mechanisation. is incorrect: There is no use of machines or modern technology. The agricultural operations are labour-intensive and performed manually using traditional implements.
Key Takeaway:
Primitive Subsistence Agriculture is characterized by its dependence on natural environmental conditions (monsoon and natural soil fertility), the use of traditional tools, and production strictly for self-consumption.
