Spread recycled walnut-hull mulch under the trees, zone 2 -- an olive & walnut orchard at the edge of Corning, CA 96021 (2026-07-20)

This orchard's own walnut-hull byproduct from the fall harvest usually gets hauled off-site at real cost; spreading it back under zone 2's tree rows as mulch instead builds soil organic matter, holds moisture, and keeps the material out of a landfill or over-application pile. Standard: UC ANR walnut/almond hull-and-shell orchard mulch recycling practice (diverting hauled ag byproduct back to the orchard floor, building soil organic matter); NRCS CPS 484 Mulching; SDG 15.3/12.5 Proof: before/after photos + application depth log + drip-line/trunk clearance confirm + GPS Method (USDA-NRCS soil-health in-situ assessment, ~45-90 min): 1. Navigate to the plot; record GPS; sketch the sampling layout. 2. Photograph each sampling station. 3. Run the infiltration ring; record time to infiltrate 1 inch. 4. Assess aggregate stability and note visible organic matter, roots, and biology. 5. If compaction is in scope, record penetrometer resistance by depth. 6. Collect 0-15 cm cores if a lab subsample is specified; bag, label, complete COC. 7. Enter all measurements with units + depth, GPS, photos into the proof record; sign. Equipment: soil auger or trowel, infiltration ring + measured water + timer, penetrometer (if compaction in scope), clean bucket, sample bags + labels, gloves, GPS phone, camera Done when: Infiltration time recorded; Aggregate stability + organic-matter observation recorded; Each in-scope measurement recorded with units and depth; GPS waypoint + station photos + site sketch

$95 proposed

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

Proof

before/after photos + application depth log + drip-line/trunk clearance confirm + GPS

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 45–90 minutes. Method of record: USDA-NRCS soil-health in-situ assessment

Bring

• soil auger or trowel
• infiltration ring + measured water + timer
• penetrometer (if compaction in scope)
• clean bucket
• sample bags + labels
• gloves
• GPS phone
• camera

Steps

1. 1. Navigate to the plot; record GPS; sketch the sampling layout.
2. 2. Photograph each sampling station.
3. 3. Run the infiltration ring; record time to infiltrate 1 inch.
4. 4. Assess aggregate stability and note visible organic matter, roots, and biology.
5. 5. If compaction is in scope, record penetrometer resistance by depth.
6. 6. Collect 0-15 cm cores if a lab subsample is specified; bag, label, complete COC.
7. 7. Enter all measurements with units + depth, GPS, photos into the proof record; sign.

If it does not match the plan

• Infiltration > 30 min/inch or high penetrometer resistance -> flag compaction; recommend cover crop / reduced traffic.
• Very low organic matter / no visible biology -> flag degraded; recommend amendment plan.

What counts as done

• Infiltration time recorded
• Aggregate stability + organic-matter observation recorded
• Each in-scope measurement recorded with units and depth
• GPS waypoint + station photos + site sketch

Proof is measured against these, not judged by taste.
