Comparing Vermicompost Yield scenarios

Run another case with Mass loss changed and the other inputs held constant. The difference in vermicompost yield then shows the effect of that assumption within this formula. Tea concentrate: Compost Tea Dilution Calculator handles this follow-up.

Arithmetic used for Vermicompost Yield

Vermicompost Yield finds a difference among Feedstock mass and Mass loss before applying its division.

For the prefilled measurements—feedstock mass at 120 lb and mass loss at 58%—the calculated answer is 50.40 lb.

Vermicompost Yield field limitation

Unprocessed bedding and worms should be excluded from finished yield. A separate estimate of compost-to-water rate comes from Compost Extract Concentration Calculator.

For Vermicompost Yield, verify the basis of Mass loss. Similar percentages can describe different totals.

Before entering feedstock mass

Prepare Feedstock mass and Mass loss for Vermicompost Yield. Keep unrelated records separate.

• Feedstock mass. Default in Vermicompost Yield: 120 lb.
• Mass loss. Vermicompost Yield enters 58% for this percentage.

Checking vermicompost yield in practice

Record moisture condition and turning history because both can change the observed volume or mass.

Vermicompost yield: interpretation

Use Vermicompost yield to estimate vermicompost mass after processing losses. Keep the Vermicompost Yield inputs beside the output. The calculation for charging solution volume remains in Biochar Nutrient Charging Calculator.

Feedstock mass lost supplements vermicompost yield in Vermicompost Yield. Test bokashi bran separately in Bokashi Bran Requirement Calculator.

Testing the vermicompost yield response

Test Vermicompost Yield with Feedstock mass at 132 lb rather than 120 lb. The displayed vermicompost yield becomes 55.44 lb instead of 50.40 lb.

The test holds mass loss constant.

Test a measured range for feedstock mass when it may alter the decision.
