Explanation:

Conservation tillage is any method of soil cultivation and crop management 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 i.e. it conserves soil by reducing erosion. Whereas, Coventional tillage leaves the soil surface bare and loosens soil particles, making them susceptible to the erosive forces of wind and water. Hence, statement 1 is correct and 3 is not correct.

? Conservation tillage reduces leaching of nutrients due to greater amounts of soil organic matter to provide binding sites. Hence, statement 2 is correct.

? Conservation tillage practices are grouped into three types: no-till, ridge- till, and mulch-till.
