Microbial diversity reduced by monocrops and excessive chemical fertilizers

"Our evaluation provided the scientific proof of microbial diversity reduction in soil that has been used to produce monocrops and yet we know, from many other scientific trials, that the production of high-quality crops requires a rich diversity of soil, and that excessive use of chemical fertilisers sharply decreases soil microbe diversity. Soil microbe diversity reduction in North and South America and the dependency of large-scale agriculture on chemical fertilisers in those regions is far from sustainable." (page 19)
