    Biofilters play a crucial role in Recirculating Aquaculture Systems by eliminating nitrogenous waste produced by aquatic organisms. They utilize nitrifying bacteria to transform toxic ammonia into nitrites, which are also harmful. Subsequently, other bacteria further convert these nitrites into harmless nitrates, ensuring water quality. Importantly, biofilters are engineered to remove pollutants rather than introduce nutrients into the system, making statement 3 inaccurate.

    The concept of ‘Small Farmer Large Field’ involves small and marginal farmers coming together to coordinate their farming practices, often synchronizing key operations like sowing, irrigation, and harvesting to achieve economies of scale. While they retain individual ownership of their land, this collective approach helps them gain the benefits typically associated with larger-scale farming, such as improved efficiency, better access to resources, and reduced costs. The correct answer is Many marginal farmers in an area organize themselves into groups and synchronize and harmonize selected agricultural operations.

    The meaning of Crop rotation is the practice of growing different crops in a specific order on the same land over multiple seasons. The goal of crop rotation is to maintain the soil’s productivity by preventing it from being used for only one set of nutrients.
    Crop rotation can have many benefits, including:
    Soil health: Improves soil structure, fertility, and organic matter
    Pest and disease control: Breaks the life cycle of pests and diseases, reducing the need for chemical pesticides
    Weed growth: Reduces weed growth
    Crop yield: Increases crop yield
    Labor efficiency: Distributes labor more evenly throughout the seasons
    A simple rotation might involve two or three crops, while a complex rotation might include a dozen or more. For example, a farmer might plant beans after harvesting corn because corn uses a lot of nitrogen and beans return nitrogen to the soil.
