Question

Which of the following is NOT true for mixed farming?

• A. It helps in maintaining soil fertility.
• B. It reduces soil erosion.
• C. It improves production level and give higher production than monoculture.
• D. It provides suitable habitat for birds.

Hint:

Mixed Farming characteristics:
- Simultaneous crop cultivation + livestock rearing.
- High internal resource recycling (dung $\rightarrow$ manure; crop residue $\rightarrow$ fodder).
- Primary goals are economic stability and soil conservation, not wild avian habitat conservation.

Answer 1

The Correct Option is D

Concept:
Mixed farming is an integrated agricultural system in which the cultivation of crops and the rearing of livestock are practiced simultaneously on the same farm.
The biological interaction between plants and animals optimizes nutrient recycling, minimizes financial risk, and promotes agricultural stability.

Step 1: Evaluation of Agronomic Benefits:
1. Soil Fertility Maintenance: Livestock dung and urine provide farmyard manure, enriching soil organic carbon, whereas leguminous forage crops fix atmospheric nitrogen, enhancing natural fertility. Hence, statement (A) is true.
2. Erosion Mitigation: The integration of cover crops, perennial grasses, and rotational pastures protects topsoil from wind and water runoff, substantially reducing erosion compared to continuous tilled monocultures. Hence, statement (B) is true.
3. Enhanced Productivity: By diversifying land use with synergistic enterprise outputs (milk, meat, grain, fiber), mixed farming yields higher total biomass and monetary returns per unit area than conventional monoculture. Hence, statement (C) is true.

Step 2: Assessment of Habitat Provision:
While mixed farming maintains higher agro-biodiversity than intensive monocultures, it is primarily an intensive production landscape shaped by human management, grazing pressure, and crop harvesting.
Such regular anthropogenic disturbances, pesticide/herbicide application, livestock trampling, and harvest operations prevent the establishment of stable, undisturbed breeding and nesting territories for wild birds.
Wild bird conservation relies on undisturbed native grasslands, wetlands, and natural forest corridors rather than working agricultural plots.
Therefore, providing a suitable habitat for wild birds is not an inherent or recognized agronomic objective of mixed farming.
Final Answer:
The statement that is not true regarding mixed farming is option (D).
