From Jack:
Aggregated Soil Service Specifications attached. As you previously noted, we should apply existing horizon skip/termination logic for cemented and organic soil horizons (implemented for soil services supporting WEPP and WEPS).
We may need to iterate on whether/how to apply logic for tillage layer surface horizons (e.g. 0-10 cm) as we do for WQM and STEP services.
And for Ksat not simple fetch and weighted horizon value, but adjustment per equation 7.17 in the Tindall reference (page 174). Frank and/or George can provide additional input if questions.
