WaSHI Vineyard LTARE Characterization Data 2023

Le résumé fourni par la source

This data represents baseline (pre-plant (April 2023) and post-plant (October 2023)) physical, chemical, and biological soil health indicator values across the recently established Washington Soil Health Initiative Vineyard at the Washington State University Irrigated Agriculture Research and Extension Center in Prosser, Washington. Soils were sampled pre- and post-planting across five management treatments and four depth intervals (0 – 15 cm, 15 – 30 cm, 30 – 60 cm, and 60 – 90 cm) of a vineyard with two wine grape cultivars (Chardonnay and Cabernet Sauvignon) on a common rootstock (1103 Paulson). Post-plant samples were also collected in the under-vine and alleyway areas to capture initial spatial variability associated with floor management zones. Samples were analyzed for a suite of chemical, biological, and physical soil health indicators. Chemical soil health indicators included total carbon (TC), total inorganic carbon (TIC), available phosphorous (P), soil pH, cation exchange capacity (CEC), and electrical conductivity (EC). Physical soil health indicators included bulk density (BD). Biological soil health indicators included total organic carbon (TOC), 24-hour mineralizable carbon (MinC), permanganate oxidizable compounds (POXC), potentially mineralizable nitrogen (PMN), autoclaved citrate-extractable (ACE) protein, and phospholipid fatty acid (PLFA) concentration and count. Most soil health indicator values were surface-weighted, with organic carbon and microbial activity concentrated in the top 30 cm, while inorganic carbon was the dominant carbon pool at depth.
