Distinguish, differentiate, compare and explain what is the difference between Conventional and Organic Farming, Subsistence vs. Commercial Agriculture, Intensive vs. Extensive Farming, and Crop Rotation. Agricultural Science Guide.
Conventional vs. Organic Farming
| Feature |
Conventional Agriculture |
Organic Agriculture |
| Soil Nutrition |
Synthetic chemical fertilizers (NPK, urea, synthetic nitrates). |
Natural organic manure, compost, vermicompost, and green manures. |
| Pest Management |
Synthetic chemical pesticides, herbicides, and fungicides. |
Biological pest control, neem extracts, crop rotation, and companion planting. |
| Environmental Impact |
High soil compaction, chemical runoff, groundwater contamination. |
Enhances soil microbiome biodiversity, carbon sequestration, and soil health. |
Subsistence Agriculture vs. Commercial Agriculture
| Parameter |
Subsistence Farming |
Commercial Farming |
| Primary Objective |
Production intended purely to feed the farmer's immediate family with minimal surplus. |
Large-scale production intended strictly for sale and profit in domestic and export markets. |
| Farm Size & Capital |
Small, fragmented landholdings; minimal financial capital investment. |
Massive consolidated acreage; heavy capital investment in machinery and infrastructure. |
| Labor & Mechanization |
Labor-intensive; relies on manual family labor and draught animals. |
Highly mechanized; relies on combine harvesters, tractors, and modern irrigation. |
Intensive Farming vs. Extensive Farming
| Parameter |
Intensive Agriculture |
Extensive Agriculture |
| Land & Input Density |
High labor and capital inputs applied per unit area of small land parcels. |
Low inputs of labor and capital applied over vast tracts of inexpensive land. |
| Yield Characteristics |
High yield per hectare; moderate to low yield per worker. |
Low yield per hectare; exceptionally high yield per agricultural worker. |
Crop Rotation vs. Multiple Cropping
| Feature |
Crop Rotation |
Multiple Cropping |
| Practice |
Growing different crops sequentially in the same field across successive seasons. |
Growing two or more different crops simultaneously on the same piece of land during a single year. |
| Primary Benefit |
Breaks pest/weed cycles and naturally replenishes soil nutrients (e.g. nitrogen-fixing legumes). |
Maximizes land productivity and ensures continuous harvest output across seasons. |
