I shall ask the following questions.
1. How can you test the soil for its acidity?
2. Is it possible to change the basic nature of the soil?
3. How can the water holding capacity of the soil be increased at a low cost.
4. Suggest methods to improve the fertility of the soil.
5. What can be done with the black cotton soil when a building is to be constructed?
6. As black cotton soil yields, and the building cracks, suggest preventive measures for it.
