Soil Temperature and Source of Nitrogen in Relation to Nitrification in Sodded and Cultivated Soils
1970
Anderson, O. E. | Jones, L. S. | Boswell, F. C.
Sods of coastal bermudagrass and fescue in permanent pastures or in sod-based rotations did not greatly inhibit nitrification of applied N at 32 C. Nitrification was strongly inhibited by sods in the finer textured soils at 6 C, especially those high in silt content. Though there were differences in nitrification rates among several sources of N, they were not strongly related to cropping practices. There were wide differences among the various N sources in the percent recovery of applied N. The percent recovery at 32 C was always higher in sodded than in cultivated soils, irrespective of source, but at 6 C the effect of cropping practice was inconsistent.
