Black Diamond Vermicompost Field Studies

 

TOXIC SOIL REMEDIATION: JULY – SEPT 2011 
ORGANIC FARM LOCATED IN ATASCADERO 

Issue: Poor germination and stunted growth of corn crop suggested toxic or diseased soil. 

Goal: Remediate soil by treating with vermicompost and vermicompost tea to out-compete disease carrying microbes and establish a community of beneficial microbiology with oxygen-dependent qualities. 

Soil found to be fairly compacted. 

SOIL TREATMENT PROGRAM: 
ONE

  • Till under corn crop 
  • Fracture soil with earth auger; add vermicompost to holes. 
  • Instill vermicompost tea into soil to 18” depth 
  • Add cover crop seed 
  • Spray vermicompost tea over field – approx 50 gallons 

TWO

  • Apply 50 gallons aerated vermicompost tea 

THREE

  • Observe weak germination confirming soil disease. 
  • Till under cover crop 
  • Add more cover crop seed 
  • Apply 50 gallons aerated vermicompost tea 

FINAL

Establishment of healthy microbiology in soil appears to be effective. Cover crop growth strong throughout affected area. Field was left unattended over winter and planted the following spring. Crop strong with high yields.
