The bottom line is that, if good fungal functioning is an important parameter of soil quality, then biosolids is at least not a negative factor.
How biosolids affects soil health is “fertile” research ground even today. While we intuitively understand biosolids benefits, scientists are looking for performance measures in soil health. This is not just for biosolids, but also for a full sweep of agricultural practices and nutrient sources. As explained in Understanding and Enhancing Soil Biological Health: The Solution for Reversing Soil Degradationbiological relationships are by far the most complex with large deficiencies in basic understanding. Many new tools and techniques have been or are being developed, thus making it more feasible to unravel these complex systems. desperately needs to meet the rapidly increasing food, feed, fiber, and fuel needs of an expanding global population.”
