Summary

Abstract Deep soil health (>30 cm) supports deep roots in dryland wheat cropping systems. However, few studies examine how tillage and climate impact soil health indicators deeper than 30 cm in dryland wheat systems. We evaluated how select soil chemical (i.e., nutrients and pH), biological (i.e., carbon [C] and nitrogen [N] fractions and ratios), and physical (i.e., mean weight diameter [MWD] of soil aggregates) health indicators were impacted by depth, tillage, and climate. We sampled soil profiles of the Palouse soil series from 0‐ to 85 cm in depth at three no‐till (NT) and three conventional till (CT) sites across a mean annual precipitation (MAP) gradient (460–660 mm) in the Palouse River watershed. NT sites, compared to CT sites, had higher total C (TC) and N (TN), permanganate o
