Illinois Field Crop Applicators Practice Test

True or false: No till or reduced tillage increases small seeded summer annuals that germinate on or near the soil surface.

1. True

2. False

3. It depends on the crop

4. Only in sandy soils

The correct answer is: False

No-till or reduced tillage practices actually facilitate the germination and establishment of small-seeded summer annuals that thrive on or near the soil surface. When soil is disturbed through traditional tillage, small-seeded species may be buried too deeply to successfully germinate. Conversely, no-till systems maintain a more favorable environment for these seeds, as they remain close to the soil surface where they have better access to light and moisture necessary for germination. This also allows for a healthier soil structure and improved moisture retention, which can further support seedling establishment. Thus, the statement that no-till or reduced tillage increases such plants is indeed true.
