Correct answer: D. Higher bulk density
- A. Higher total pore space
- B. Lowe bulk density
- C. None of the above
- D. Higher bulk density
Explanation
No-tillage leaves the soil undisturbed and avoids loosening by ploughing, so bulk density commonly increases, especially in the upper layer. This generally means lower total pore space and fewer large pores.
