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:
Statement 1 is correct: Zero tillage is a method of farming that involves sowing crop seeds directly into the soil without disturbing it. This method has several advantages.
In zero tillage, the residue of the previous crop is left on the field, which acts as a natural mulch, reducing soil erosion and improving soil fertility. Therefore, there is no need to burn the residue of the previous crop before sowing wheat. Statement 2 is correct: In zero tillage, seeds are directly planted into the soil, eliminating the need for a nursery of rice saplings. This not only saves time and labor but also reduces the cost of cultivation. Statement 3 is correct: Carbon sequestration refers to the process of capture and long-term storage of atmospheric carbon dioxide. In zero tillage, the carbon in the crop residue is returned to the soil, which helps in carbon sequestration. Therefore, all three statements are correct.
