Project Overview

The gardens surrounding Old Economy Village have just begun their transformation after multiple years of decline. Initial plant health, crop steering, integrated pest management planning and soil health will be essential prior to full scale restoration. While maintaining historically significant landscapes, fiber flax plots could grant insights and potential solutions to modern day challenges on evolved grounds. These insights include, but are not limited to the following: 

 

  • Nutrient imbalances and sustainable/safe resolution options 

  • Heavy metal toxicity potential from industrialization 

  • Pathogen loads/risks and potential cultural (non-chemical) control solutions 

  • Micro-climates and potential gradients across the historic gardens 

  • Irrigation steering for future transplants 

  • Soil structure and potential points of improvement 

  • Irrigation water purity and elemental components from water authority source or antiquated infrastructures 

  • Land surface temperatures and variances compared to early data sets relative to soil moisture and atmospheric temperature/humidity 

  • The viability of fiber flax to be used in soil remediation for industrially polluted or calcareous land in the greater Pittsburgh area

Purpose

  • To evaluate the potential utility of historically significant fiber flax as a means of soil remediation and potential to correct nutrient imbalances while providing insights into potential heavy metal pollution to soils at Old Economy Village due to proximal industrial sites.  

  • Launch 2025 educational events through lectures, signage and website page establishment to discuss research, site history and sustainable farming practices.  

  • Prep ground for new transplants or trials following research finalization and move forward using sustainable, economical & environmentally friendly practices. These efforts are intended to reclaim soil health while creating historically significant spaces for community enjoyment.

Project Timelines & Data Points,
April - September 2025

  • January - March 2025: Prepare 2 plots for seeding (approx. 1000sqft each) using weed-block fabric/plastic and minimal tilling of the upper 2-3 inches of soil

  • March 2025: Deploy data loggers to collect air temperature, % RH, soil temperature and soil moisture. Build and test T-tape irrigation kits

  • EOM March 2025: Submit soil samples and irrigation water samples for testing at an accredited agricultural lab on the day of seeding

  • April WK 1: Seed (using the Jang 3 Point Seeder) and establish 2 varieties of flax per plot and split 50/50 across the area in equal rates

  • April-September 2025: Document germination, characteristics, events impacting data, height throughout growing season, weeds or significant species appearing

  • September 2025: Submit plant and soil samples for testing to prior to harvest (approx. 100 days total growing cycle)

  • Mid-September 2025: Manually harvest by hand pulling plants and bundling. (2.5 day period to complete manual harvest, Plot B harvested first due to maturity signs of plants)

  • Project Duration: Document germination dates, height progression, nutrient deficiencies/excesses, pest/pathogen, harvest date/yield comparisons and significant plot variances in invasives, weeds, soil characteristics, ease of manual harvest
