Webthe difference of soils. Soils which have high nitrifying activities at ordinary temperatures (around 25°C) show fairly good nitrification even at lower temperatures (1, 2, 5). However, in nitrification by usual experimental methods, the amount of nitrate produced can be only estimated while nitrifying organisms are in creasing or decreasing ... WebFeb 28, 2013 · Nitrification is one of the most important processes among nitrogen (N) transformations in soil and there is a tight relationship between mineralization and immobilization. This nitrification reaction is significantly inhibited by soil fumigation (Welsh et al. 1998; Yamamoto et al. 2008; Zhang et al. 2011 ). Fumigants are capable of retarding ...
