In shifting cultivation, a forest pipeline at one end and have rotating patch is selected, its vegetation is burnt nozzles at the top end. When water and its ash is mixed with the soil. Then flows through the main pipes under  pressure, it escapes through the rotating nozzles and get sprinkled over the crop plants. Use of sprinklers is recommended for sandy soil and on uneven land where proper distribution of water is not possible. 49. (a) : Father of green revolution in India is Prof. M.S. Swaminathan. He introduced high-yielding varieties of foreign origin in Indian agriculture, developed new varieties of all Indian crops and evolved new methods and techniques of raising agricultural production. 50. (b): Agronomy is the study of developing new techniques for improving agricultural practices. Agronomists today are involved with many issues including producing food, creating healthier food, managing environmental impact of agriculture and creating energy from plants. Agronomists often specializes in areas such as crop rotation, irrigation and drainage, plant breeding, soil fertility, weed and pest control.  Education Adda Official Whatsapp Channel (Link) https://whatsapp.com/channel/0029VaB5398I7BeE6kEHgG3n Education Adda Official Telegram Channel (Link) https://t.me/shadabkhan308 Education Adda Official Instagram (Link) https://instagram.com/education_adda_1?igshid=MzNlNGNkZWQ4Mg== Education Adda Official Facebook (Link) https://www.facebook.com/educationaddaea For Education Adda Review https://maps.app.goo.gl/XqWhCtffQ9BPeU9G8 Shadab sir Official Instagram (Link) https://instagram.com/shadabperwezsp?igshid=ZDc4ODBmNjlmNQ== Parwez sir Official Instagram (Link) https://instagram.com/perweznadim?igshid=MzRlODBiNWFlZA==
