Core Books/NCERT
Zero Tillage is the process of agriculture that promotes conservation agriculture. Here the soil is not tilled and left with at least 30% of cover over soil which may be previous crop. When wheat seeds are sown in soil using happy seeder, the rice stalks act as mulch. It not only prevents harmful gases that are released when stubbles are burnt but also provides enhanced nutrients and improves moisture holding capacity of the soil. The same is also true for rice when it is directly sown without transplantation. As the soil is not tilled the remains of previous crop hold carbon and prevent it from entering atmosphere as carbon di oxide. All statements are correct. Therefore, the correct answer is (d).
