Field Decomposition
Fungal activity defines the biochemical process where organisms break down pectin layers binding flax fibres to the woody stalk under atmospheric conditions. Severe dew retting degradation results in the destruction of the cellulose itself if the plants remain on the damp ground for too long. Optimal moisture cycles between rain and sun are required to keep the organisms working effectively.
Visual Assessment
Inspections look for greyish or brownish discolouration as signs that the inner core has begun to weaken. Fibres feel brittle and dusty rather than cool and oily to the touch when the stage has progressed too deep into the bundle. Observers record the depth of penetration in the field report to determine the exact date for harvesting.
Structural Failure
Strength loss happens rapidly once the fungi move past the stem interface. Buyers pay a reduced premium for stock showing excessive breakdown because the resulting yarn will produce low strength weave. Each batch undergoes a pull test to verify that the core integrity remains within acceptable commercial tolerances, ensuring that only the stems with intact bundles reach the heavy mechanised scutching equipment where the most intense physical force is applied to the raw plant stock.
