Thus, germination occurs primarily in plant and fungal species. For farmers in an agroecosystem context the are 3 components to consider in terms of why soil biology is important; the natural processes themselves (soil engineering, litter transformation and micro-food web participation), the impact of management on these processes, and the combined effect of the first two on plant performance.
