Soil Respiration And Nutrient Cycling In Wooded Communities Developing In Grassland, Rebecca L. Mcculley, S. R. Archer, T. W. Boutton, F. M. Hons, D. A. Zuberer

Grasslands and savannas worldwide are experiencing increases in woody plant abundance. In the subtropical Rio Grande Plains of southern Texas and northern Mexico, this change in physiognomy typically results in soil C and N accumulation. The extent to which this accumulation is the result of increased C and N inputs vs. decreased losses is not known. To address this issue, we compared soil C and N pools, soil respiration, soil microbial biomass, and potential C and N mineralization and nitrification rates in remnant grassland communities and adjacent woody plant communities known to have developed on grassland within the past 100 …
