Nitrification of ammoniacal (NH4+) N added as (NH4)2SO4 to different soils of western USA and incubated at 20, 25, 35 and 40C with moisture at 0.3 bar moisture tension was investigated. In all soils from northern regions, nitrification was faster at 20 and 25C than at 35 and 40C. The reverse was true in the case of the southern soils which nitrified fastest at 35C. Nitrites accumulated in larger quantities under the temperature conditions less favorable for nitrification.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
