Including pulses in crop rotations helps improve:

The correct answer is: d) All of the above

Including pulses in crop rotations helps improve soil fertility, pest control, and income for farmers.

• Soil fertility: Pulses fix nitrogen from the atmosphere, which helps to improve soil fertility. This is because nitrogen is a key nutrient for plant growth.
• Pest control: Pulses can help to control pests by providing a food source for beneficial insects. Beneficial insects help to control pests by eating them or by laying eggs on them.
• Income for farmers: Pulses can help to increase income for farmers by providing a valuable source of food. Pulses are a good source of protein, fiber, and other nutrients. They are also a good source of income for farmers because they are relatively easy to grow and they can be grown in a variety of climates.

In addition to the above, pulses also have a number of other benefits, including:

• Reduced water use: Pulses require less water to grow than other crops, such as cereals. This is because pulses have a deep root system that allows them to access water that is deep in the soil.
• Reduced greenhouse gas emissions: Pulses help to reduce greenhouse gas emissions by fixing nitrogen from the atmosphere. This helps to reduce the need for synthetic fertilizers, which produce greenhouse gases when they are manufactured and applied to crops.
• Improved biodiversity: Pulses help to improve biodiversity by providing a food source for a variety of animals, including birds, insects, and mammals.
• Sustainable agriculture: Pulses can be used in sustainable agriculture practices, such as crop rotation and intercropping. This helps to improve soil health and reduce the use of pesticides and fertilizers.

Overall, including pulses in crop rotations has a number of benefits for farmers, the environment, and society as a whole.
