Types of Farming

Subsistence farming is categorized into primitive and intensive systems, depending on the level of technology and land availability.

• Primitive Subsistence (Shifting Cultivation & Nomadic Herding): Characterized by small plots, use of primitive tools (hoe, dao, digging sticks), and reliance on monsoon/natural fertility. Also known as slash-and-burn or Jhuming in Northeast India.
• Intensive Subsistence: Found in densely populated regions of monsoon Asia. Farms are small, but high inputs of labor, manures, and irrigation are used to get maximum yield from the limited land. Double or triple cropping is common.

Commercial farming uses modern inputs like HYV seeds, chemical fertilizers, and insecticides to achieve higher yields for sale in national or international markets.

• Commercial Grain Cultivation: Practiced in temperate grasslands (Prairies, Steppes, Pampas). Farms are massive (hundreds of hectares), highly mechanized, and specialize in single grains like wheat or maize.
• Mixed Farming: Common in Europe and North America. Crops (wheat, barley, oats, fodder) are grown alongside animal husbandry. Crop rotation is strictly followed to maintain soil fertility.
• Plantation Agriculture: Introduced by Europeans in the tropics. Characterized by large estates, single-crop specialization, heavy capital investment, scientific methods, and processing facilities on or near the estate.

Shifting cultivation is known by different local names globally and within India. It is a frequent area of questioning in competitive exams:

To feed growing populations while preserving ecosystems, agriculture is adopting sustainable farming systems:

• Organic Farming: Replaces chemical inputs with organic manures, bio-fertilizers, and natural pest control to maintain eco-health.
• Precision Agriculture: Uses technology (GPS, remote sensing, drones) to supply exact amounts of water, seeds, and nutrients, avoiding wastage.
• Dryland Farming: Adopted in regions with less than 75 cm annual rainfall. Focuses on moisture conservation and drought-resistant crops (millets, pulses).
• Vertical Farming & Hydroponics: Cultivating plants indoors in stacked layers, using nutrient-rich water solutions without soil. Highly space and water efficient.
