| Abstract/Contents: | Factors limiting nitrate utilization by plants in acidic and calcareous grasslands were examined by analysis of control and ammonium-fertilized plant and soil material from the field. Plants from these habitats maintained their maximum capacity to synthesize nitrate reductase throughout the growing season. In both soil types, nitrate formation was limited by the ammonium supply. Increasing the availability of soil ammonium stimulated the rate of nitrate utilization. However, in plants from calcareous soils, water stress often impaired nitrate reductase activity. Consequently, during periods of drought, nitrate utilization may be higher in acidic soils than in closely adjacent calcareous sites. |
