Clayey soil is useful for crops. Do you agree with this statement? Why is sandy soil not suitable?
Clayey soil is indeed beneficial for crops. This soil type is notable for its ability to retain water and moisture, making it exceptionally suitable for growing crops such as wheat and gram. Additionally, clayey soil is rich in humus, which provides an ideal environment for crop growth.
On the other hand, sandy soils are not ideal for most crops due to their high porosity and low water retention capacity. Plants need water for essential processes like photosynthesis. When planted in sandy soil, they may wilt and die due to inadequate water availability.
India has cropping seasons.
A) One
B) Two
C) Three
D) Four

How does the type of cropping pattern practised by farmers impact the biodiversity of the area, and why is it important to maintain this biodiversity?
The type of cropping pattern practised by farmers significantly impacts the biodiversity of the area. Practices like monoculture, where the same crop is grown year after year, can lead to a decrease in biodiversity as it enables specific pests and diseases to become established. On the other hand, crop rotation and intercropping, which involve growing different types of crops in the same area, can help to improve biodiversity. These practices discourage pests and diseases and promote a diversity of organisms in the soil ecosystem. Maintaining biodiversity is crucial as it ensures long-term soil fertility, aids in pest and disease control, and contributes to an overall healthy ecosystem.
Can you describe the advantages and disadvantages between traditional and modern methods of irrigation, and how it impacts crop yield and the environment?
