What is/are the advantage/advantages of zero tillage in agriculture?

1. Sowing of wheat is possible without burning the residue of previous crop.
2. Without the need for nursery of rice saplings, direct planting of paddy seeds in the wet soil is possible.
3. Carbon sequestration in the soil is possible. Select the correct answer using the code given below:

Zero tillage refers to a method of cultivation where the soil is not ploughed before sowing seeds.

Statement 1 is correct: Zero-till farming allows for the sowing of wheat crops directly into harvested fields without disturbing the soil or burning crop residue. The Happy Seeder is a technique used for this purpose, eliminating the need to burn crop residue.

Statement 2 is correct: Direct Seeded Rice (DSR) is gaining popularity because it requires less input. DSR involves sowing pre-germinated seeds directly into wet soil, standing water, or dry seedbeds, eliminating the need for rice nurseries.

Statement 3 is correct: No-tillage practices in agro-ecosystems are recommended for enhancing carbon sequestration in soils.

Therefore, 1, 2, and 3 are correct.
