The primary ecological concern arising from current agricultural practices in India is soil degradation. Overreliance on chemical fertilizers has led to a significant decline in soil organic carbon levels, which is crucial for maintaining soil health and productivity. This degradation not only affects crop yields but also undermines the soil’s ability to sequester carbon, contributing to broader environmental issues such as climate change. Maintaining soil health is vital for sustainable agriculture and food security.

Ecological Concerns in Indian Agriculture
Current agricultural practices in India face numerous ecological challenges, with soil degradation standing out as the primary concern.
Soil Degradation Explained
- Loss of Nutrients: Intensive farming techniques often rely on chemical fertilizers, which can deplete essential nutrients in the soil over time.
- Erosion: Continuous tilling and monoculture practices lead to soil erosion, reducing the land's fertility and its ability to retain moisture.
- Compaction: Heavy machinery used in farming compresses the soil, affecting its structure and limiting root growth, which can further exacerbate erosion.
Impact on Biodiversity
- Reduction in Soil Microorganisms: The use of pesticides and herbicides not only targets pests but also harms beneficial soil microorganisms crucial for maintaining soil health.
- Loss of Crop Diversity: Monoculture practices diminish the variety of crops grown, which can lead to a decrease in biodiversity and resilience in the ecosystem.
Long-term Consequences
- Decreased Agricultural Productivity: As soil quality declines, productivity can also drop, leading to food insecurity.
- Water Quality Issues: Soil degradation can result in increased runoff and sedimentation in water bodies, affecting water quality and aquatic ecosystems.
In summary, while enhanced crop yields (option 'C') and improved water retention (option 'D') are often seen as benefits of modern agricultural methods, they come at the cost of significant soil degradation, which poses a serious long-term ecological threat in India. Addressing these issues is crucial for sustainable agricultural practices and environmental health.
