To determine which of the options are sustainable farming techniques, we need to understand the concept of sustainability in agriculture. Sustainable farming aims to protect the environment, maintain soil fertility, and promote long-term food production without harming natural resources.
Now let's analyze each option to identify the sustainable farming techniques:
1. Tilling soil frequently: Tilling refers to breaking up and loosening the soil surface. While tilling can be necessary for preparing the soil, frequent tilling can lead to soil erosion and loss of organic matter, which is not sustainable. So, this is not a sustainable farming technique.
2. Rotating crops each year: Crop rotation involves planting different crops in a particular sequence on the same piece of land over time. This technique helps prevent diseases, pests, and nutrient depletion while improving soil health. Crop rotation is considered a sustainable farming technique as it enhances long-term productivity and reduces dependence on fertilizers and pesticides.
3. Planting a single crop over a large area: This practice is known as monoculture farming. Monoculture farming focuses on growing a single crop over a large area. While this method may simplify farming operations, it poses risks such as increased vulnerability to pests and diseases, soil nutrient depletion, and decreased biodiversity. Therefore, planting a single crop over a large area is not a sustainable farming technique.
4. Limiting agriculture to rural areas: This statement refers to zoning agricultural activities exclusively in rural areas. While it can help protect urban areas from pollution or conflicts with other land uses, it does not inherently promote sustainable farming practices.
5. Planting trees in between rows of crops: This technique is called agroforestry or alley cropping. Planting trees among crops provides multiple benefits like shade, windbreak, erosion prevention, and improved biodiversity. The trees can also contribute organic matter to the soil, enhancing its fertility. Planting trees in between rows of crops is considered a sustainable farming technique.
From the analysis, the two sustainable farming techniques are:
- Rotating crops each year.
- Planting trees in between rows of crops.
