The correct answer is: d) All of the above

Organic farming practices can help improve soil health in Tamil Nadu by:

  • Increasing soil organic matter: Organic matter is the part of the soil that comes from living things, such as plants, animals, and microorganisms. It helps to improve soil structure, water retention, and nutrient availability.
  • Improving soil structure: Soil structure refers to the way that the soil particles are arranged. A good soil structure is loose and crumbly, which allows for good drainage and aeration.
  • Reducing dependence on chemical fertilizers: Chemical fertilizers can damage soil health by disrupting the natural balance of microorganisms and nutrients. Organic farming practices can help to reduce the need for chemical fertilizers by using natural methods to improve soil fertility.

In addition to these benefits, organic farming practices can also help to improve water quality, reduce soil erosion, and protect wildlife.
