Vedclass · Answer

(A) Nitrification is a biological process carried out by chemoautotrophic bacteria such as $Nitrosomonas$ and $Nitrobacter$.These bacteria are highly sensitive to environmental conditions.The process of nitrification is significantly influenced by the $pH$ of the soil.Nitrification occurs most efficiently in neutral to slightly alkaline soils ($pH$ $7.0$ to $8.5$).In acidic soils,the activity of nitrifying bacteria is severely inhibited,making $pH$ the primary limiting factor for this process.
