Answer 2

Explanation:

1. Slash-and-burn agroecosystems are important to rural poor and indigenous peoples in the developing world. Ecologically sound slash-and-burn agriculture is sustainable because it does not depend upon outside inputs based on fossil energy for fertilizers, pesticides and irrigation. One means of demonstrating the soundness of slash-and-burn agroecosystems is to prove empirically the ecological compatibility of this system of crop production. This paper examines the ecological sustainability of slash-and-burn agriculture based on the productivity of soil resources.

2. Ragi is also a very rich source of minerals. It has been found to have between 5-30 times the calcium content found in other cereals. It is also rich in phosphorus, potassium and iron. Calcium is of course an important component in maintaining bone density and health.

3. Rice is the main food crop of Eastern India. Sugarcane is main food crop in Southern India.

4. Zaid season : In between the rabi and the kharif seasons, there is a short season during the summer months known as the Zaid season.

5. Plantation agriculture is a form of commercial farming where crops are grown for profit. Large land areas are needed for this type of agriculture. Countries that have plantation agriculture usually experience tropical climate with high annual temperatures and receive high annual rainfall.
