Wilting point Field capacity Saturation

Each line is one sensor depth, averaged across CLBJ's replicate soil plots. Values are volumetric water content (VWC, %) aggregated from NEON's 30-minute readings, 2021-07 through 2026-06. Use the date range above to zoom into a shorter window at any resolution.

* Wilting point (WP), field capacity (FC), and saturation (Sat) reference zones are computed per depth using the Saxton-Rawls (2006) pedotransfer function, from SSURGO soil texture (sand/clay/organic matter) at CLBJ's soil pit location (33.4014, −97.5673 — dominant component: Duffau series). Click a depth button above to isolate that depth's line, show its zones, and shade the min–max range within each plotted period (still aggregated from NEON's underlying 30-minute readings, not a raw sub-daily trace); click again to show all depths.
