Explanation:

Conservation tillage is any method of soil cultivation that leaves the previous year’s crop residue (such as corn stalks or wheat stubble) on fields before and after planting the next crop, to reduce soil erosion and runoff.
Conservation tillage systems also benefit farmers by reducing fuel consumption and soil compaction. By reducing the number of times the farmer travels over the field, farmers realize significant savings in fuel and labor. There are some concerns about it, particularly concerning impacts on water quality and on pests.So statement 3rd is incorrect.
