Surface Soil Nutrients

**The objective of the present research was to determine whether
there have been changes in the structure and function of the surface
(0-20cm) soil system, the zone most affected by litter
decomposition, which is associated with the rapid movement of
mesquite from historical habitats (arroyo and playa fringe) into
recent habitats (grassland and dunes). We hypothesized that the
soil biotic communities would be poorly developed in the recent
mesquite habitats because of lower soil C and nutrient
concentrations. As a result of these differences we predicted lower
rates of net N mineralization in the soils from recent mesquite
habitats.
Data set contains analyses for gravimetric soil moisture, pH,
phosphate, total Kjeldahl nitrogen, total phosphorus, NO3-N nitrogen
mineralization, total inorganic nitrogen, NH4-N nitrogen
mineralization, organic carbon, inorganic carbon, total roots, tap
roots, intermediate roots, and fine roots.
