Which one among the following statements is NOT correct for "Organic Farming"?

Promotes monoculture, single crop in the same space.

Birds are introduced to eat insects.

Promotes weed suppression rather than weed elimination.

Bone meal, human and animal waste are used as fertilizers.

✅ Correct Option: 1

Option 1 -> Organic farming discourages monoculture and instead promotes crop diversity, rotation, and polyculture to maintain soil health and prevent pest buildup.

Option 2 -> Biological pest control using birds and beneficial insects is a core principle of organic farming to avoid chemical pesticides.

Option 3 -> Organic farming manages weeds through natural suppression methods like mulching and cover crops rather than aiming for complete elimination with herbicides.

Option 4 -> Natural fertilizers including bone meal, compost, and animal manure are essential components of organic farming practices.

Hence, Option 1 -> Monoculture (growing single crop repeatedly in same space) is actually contrary to organic farming principles, which emphasize crop diversity, rotation, and polyculture to maintain ecological balance and soil fertility -> correct
