Seed Germination Delay

PED’s 47-day lab study pit CNP-17+—a biodegradable Durable Inputs™ coating—against raw, wax-coated, and polymer CRF calcium nitrate. Every control dissolved within 72 hours; CNP-17+ still held one-third of its mass at Day 47, delivering a smooth six-week nutrient curve without micro-plastics.

Executive Summary

In Spring 2025, PED conducted an internal observation to evaluate PED’s coating ability to influence seed emergence timing. Using Wando pea seeds in untreated native soil, the trial revealed:

19-day difference in visible germination between coated and uncoated seeds
No rot, no fungal damage, and no visible degradation on coated seeds
Suggests a moisture-resistant barrier effect that delays germination intentionally

This test reinforces PED‘s coating potential as a plastic-free, shelf-stable coating with field-ready functionality—particularly valuable in regenerative, organic, or timing-sensitive systems.

Observation Snapshot

Attribute	Control (Uncoated)	Coated (10%)
Planted	April 25, 2025	April 25, 2025
Germination Visible	~Day 7	Day 19
Condition Observed	Healthy leaves, typical growth	No emergence, seed intact
Soil	Native SC soil	Same
Moisture Regimen	Hand-watered as needed	Identical

Why This Matters

Seed emergence timing is critical.

Too early and you risk rot, frost, or weed competition. Too late and you lose valuable growing days. Most coatings can’t solve this—they either dissolve immediately or rely on synthetic materials not fit for organic use.

the PED coating changes that.

Delays moisture penetration without synthetic barriers
Provides a buffer during unpredictable weather
Protects viability under pressure (humidity, microbial exposure)

Practical Use Cases

Relay Planting: Delay emergence until a prior crop clears
Flood-Prone Fields: Prevent premature sprouting in standing water
Early Planting: Hold germination until soil temps are safe
Systems Compliant: coating without plastic, paraffin, or synthetic binders
Seed Shelf Life: Delay breakdown from humidity during storage or transport

Limitations & Next Steps

This was a small-scale, non-replicated test—designed to observe visual delay, not provide statistical validation.

PED is already taking next steps to:

Conduct replicated greenhouse and field trials
Collaborate with academic partners for third-party validation
Measure degradation timing, viability curves, and coating behavior across crops
