Use our Compost Calculator to quickly determine how much compost you’ll need for your application and the cost per acre. Enter Total Acreage, Dilution Ratio, and desired Gallons/ Acre or Pounds/Acre. The variable-speed auger in our Compost Extractors provides precise control over extract concentration. To learn how to fine-tune your dilution settings, check out our blog post: Calibrating the Bio-Extractor. Prices are calculated from our Bulk Compost selection. A common application rate is 10 gallons/acre or 2 lbs./acre at a 1:5 dilution.
