Slash and burn cultivation is another name of–

Correct option is A

Option (a): Correct
• Slash-and-burn is a traditional agricultural practice where forests or vegetation are cut (slashed) and burned to clear land for farming.
• Burning releases nutrients like potash into the soil, making it temporarily fertile.
• After 1–2 cropping seasons, fertility declines, and farmers shift to a new plot, leaving the old one fallow for natural regeneration.
• This cyclic movement of cultivation makes it exactly the same as shifting cultivation, practiced in many tribal and hilly regions.
Option (b): Incorrect
• Organic farming promotes natural manures, biological pest control, and prohibits chemical fertilizers; it does not involve burning forests or shifting fields.
Option (c): Incorrect
• Precision farming uses high-tech tools (GPS, sensors, drones, variable-rate technology).
• It focuses on accurate input application, not clearing land by fire.
Option (d): Incorrect
• Conservation farming emphasizes minimum soil disturbance, residue retention, and soil protection—slash-and-burn causes nutrient loss, erosion, and deforestation, opposite to conservation goals.
