Is difference because they are re-created soils or is it due to N deposition? What’s happening in the undisturbed forests?

Relationships between abundance of microbial communities and soil chemical characteristics and atmospheric deposition

Questions Has there been a fundamental change in: dominant N forms in soil process rates of N cycling in soils soil microbial N-cycling community esp. nitrifiers foliar N:nutrient ratios esp. N:P may be early signs of N saturation with attendant implications for tree health
