Nitrogen mineralization in acid sulfate soils

Mineralization of Nitrogen in Organic Soils

The effect of fluctuating seasonal temperatures on the release of soluble NO3-N, NHJ-N, soluble organic N (SON), and solube organic C (SOC) into drainage effluent during soil organic matter mineralization was measured on organic soil profiles obtained intact from various locations in Florida. Soil columns were leached once every 25 days, followed by applying a suction of 100 cm. Soil columns we...

Nitrogen Mineralization in Soils of a Chaparral Watershed in Arizona

This study was undertaken to extend our knowledge of nutrient availability in soils of the Arizona chaparral. Our objective was to determine the effect of shrub species and topographic aspect on N mineralization of soils from a watershed in central Arizona and to relate N mineralization to other soil properties. Soil for an incubation study was collected from the 0to 2and 2to 10-cm soil layers ...
