Read the story of Rinjha and answer the question that follows : Story of Rinjha Rinjha lived with her family in a small village at the outskirts of Diphu in Assam. She enjoys watching her family members clearing, slashing and burning a patch of land for cultivation. She often helps them in irrigating the fields with water running through a bamboo canal from the nearby spring. She loves the surroundings and wants to stay here as long as she can, but this little girl has no idea about the declining fertility of the soil and her family's search for a fresh patch of land in the next season. Suggest any three measures to Rinjha so that the fertility of the soil of her fields remains intact for a long time.
