资源简介：
This dataset contains soil physical, chemical, and biological measurements from a long-term conservation agriculture experiment at the Conservation Agriculture Systems Innovation (CASI) site in Five Points, California. Data were collected from undisturbed soil cores sampled in October 2019, after 19 years of differential management comparing conservation tillage with cover crops (CTCC) versus standard tillage without cover crops (STNC).
The dataset includes: (1) soil water retention curves measured using the HYPROP evaporation method; (2) time-series CO2 efflux measurements across a controlled moisture gradient from saturation to approximately -80 kPa; (3) total carbon and nitrogen content determined by elemental combustion; (4) bulk density and porosity measurements; and (5) fitted van Genuchten-PDI model parameters for each soil core.
These data support the finding that conservation management significantly increases soil carbon stocks while simultaneously enhancing carbon-specific re..., , # Soil physical properties, carbon and nitrogen stocks, and heterotrophic respiration data from a 19-year conservation agriculture experiment in California's San Joaquin Valley
