Name two methods of soil conservation practised in India.
Show Hint
Solution and Explanation
Terracing is a method used in hilly areas where the land is divided into a series of flat steps. This helps to reduce the speed of water runoff, preventing soil erosion. The flat surface allows for better water retention and provides more space for crops to grow. Terracing is common in the hilly regions of Himachal Pradesh, Uttarakhand, and parts of the Western Ghats.
Step 2: Contour Ploughing.
Contour ploughing involves ploughing the land along the contours of the slopes, rather than up and down the hill. This helps to reduce water runoff and allows the soil to retain moisture better. It also reduces the erosion of topsoil and is commonly practised in regions with gentle slopes. This method is used in states like Madhya Pradesh, Maharashtra, and Andhra Pradesh.

- Object-Oriented Programming
- Write a program to accept a two-dimensional integer array of order \( 4 \times 5 \) as input from the user. Check if it is a Sparse Matrix or not. A matrix is considered to be a sparse, if the total number of zero elements is greater than the total number of non-zero elements. Print appropriate messages.
