What benefit does conservation tillage provide for irrigation practices?

Conservation tillage is beneficial for irrigation practices primarily because it improves water infiltration and reduces runoff. This practice involves minimizing the disturbance of the soil, which helps maintain its structural integrity and fosters a better environment for water absorption. When soil is disturbed less, it can hold onto moisture more effectively, leading to increased infiltration rates. As water moves into the soil rather than running off the surface, it is available for crops, enhancing their growth and reducing the need for additional irrigation.

In contrast, the other responses do not accurately reflect the advantages of conservation tillage. For instance, decreasing crop yield goes against the intended benefits of irrigating effectively and can be attributed to poor water management practices rather than soil conservation techniques. Additionally, conservation tillage does not require more frequent irrigation; in fact, it often decreases the overall need for irrigation due to improved soil moisture retention. Lastly, while proper soil management can enhance nutrient utilization, conservation tillage does not eliminate the need for fertilization, as crops still require essential nutrients for optimal growth.
