What is the difference between minimum tillage and zero tillage?

Minimum tillage involves reducing the amount of soil disturbance during land preparation, allowing for some tilling while still promoting soil health and moisture retention. In contrast, zero tillage, or no-till farming, eliminates soil disturbance entirely by planting crops directly into undisturbed soil, which helps preserve soil structure and enhances biodiversity. Both practices aim to improve soil conservation, but zero tillage takes a more extreme approach to maintain soil integrity.
