Which consequence results when high soil acidity inhibits free-living diazotroph activity?

💡 Explanation

When soil becomes highly acidic, nitrogen fixation by diazotrophs slows down because enzyme activity is pH-sensitive, therefore less inorganic nitrogen is available to plants, rather than enhanced nutrient uptake or disease resistance, which need nitrogen.
