Activity of nitrification processes in the fall and winter months
1932
Bartholomew, R.P.
Results of experiments to determine whether nitrification takes place in soils which are subjected to cold periods with intermittent warm periods are reported. Studies to determine the value and efficiency of cover crops are also reported. The results may be summarized as follows: (1) Nitrates were produced in soil during the fall and winter months; (2) relatively large amounts of nitrates disappeared from soils not planted to cover crops; and (3) cover crops are efficient means of preventing loss of soluble nitrogenous compounds from the soil.
