Question

what do we call a type of farming where a farmer harvests his crops but does not openly till the soil in order to replant a new crop? high-till farming no-till farming

Explanation:

The question describes a farming method where the soil is not tilled (plowed) when replanting. "No - till farming" matches this description as it involves growing crops without disturbing the soil through tillage. "High - till farming" would imply a lot of tilling, which is the opposite of what is described.

Answer:

B. No - till farming
