Branching workshop
Guided feel-test workshop
Step through moist cast strength, ribbon length, and grittiness with hand-cue illustrations. Each branch resolves to a USDA texture class plus drainage and workability notes you can act on.

The ribbon-to-class loop
Core field sequence
01
Moisten & cast
Work a sample to field moisture and test cast strength with illustrated hand cues.
02
Ribbon length
Press a ribbon between thumb and forefinger; band length narrows the texture path.
03
Grittiness check
Sand–silt–clay feel branches resolve a named USDA class with drainage notes.
04
Crops & cards
Match covers, desk amendments, drill recognition, and pin beds offline.
Workshop tools in the pocket
Dense educational utility
Interactive map
Live USDA texture triangle
Tap or drag sand, loam, silt loam, clay loam, clay, and kin zones to open field-feel cues, typical problems like crusting or puddling, and jumps into crops and amendments.
Catalog filter
Crop & cover fit browser
Filter a seeded catalog by preferred texture and drainage, star a study set, and open side-by-side cards that explain why a crop thrives—or struggles—in that class.
Scenario desk
Amendment scenario desk
Set current class versus target feel, then review educational mix directions—compost bulk, coarse-sand caution, gypsum context, OM goals—with non-prescription wording and verify-locally prompts.
Memory + places
Site cards & recognition drills
Save named beds or paddock corners with class, photo, checklist, and notes on-device. Timed quizzes on ribbons, triangle regions, and crop pairs build mastery streaks offline.
Field timing
Seasonal coach & field widget
Know when wet, frozen, or powder-dry ground skews results, how to re-moisten samples, and compaction red flags—plus a Home Screen ribbon-length cheat sheet with resume deep link. Built as a full seeded library for orchardists, homesteaders, master-gardener trainees, and ag-program students—not a weather gadget.
About the lab
SoilRibbon Feel Lab turns the classic ribbon-and-ball test into a branching field workshop for home orchardists, homesteaders, master-gardener trainees, and ag students.
Work a moist sample through cast strength, ribbon-length bands, and sand–silt–clay grittiness with illustrated hand cues until you resolve a named USDA texture class—complete with plain-language drainage and workability notes.
Explore that class on a live texture triangle, filter vegetables, fruits, forages, and covers that prefer it, and desk out educational amendment paths toward a target feel. Timed recognition drills lock in cues; offline site cards pin beds and paddock corners with optional photos and checklists.
Seeded at first launch with the full class set, crop catalog, and feel-test diagrams—so the lab is ready when your hands are muddy.
Who it is forHome orchard beds, homestead paddocks, master-gardener training, and ag-program practice—not a thin soil-fact list.
What stays localSite cards, photos, checklists, and drill streaks live on-device for muddy offline days.
