Silage clamp stock Calculator
Estimate fresh and available dry-matter stock in a clamp. This free silage clamp stock calculator shows the calculation and its assumptions so you can compare your own figures.
Your results
Estimate fresh and available dry-matter stock in a clamp.
Calculated outcomes
- Volume M3
- 900 m³
- Fresh Tonnes
- 585 t
Assumptions and estimates
- Method: Fresh tonnes = volume × fresh density ÷ 1,000. Retained stock applies storage loss; dry matter applies measured DM fraction.
- Use average actual height, representative density and forage analysis. Density and loss vary with chop length, packing, fermentation and storage.

How the silage clamp stock calculation works
Fresh tonnes = volume × fresh density ÷ 1,000. Retained stock applies storage loss; dry matter applies measured DM fraction.
Use average actual height, representative density and forage analysis. Density and loss vary with chop length, packing, fermentation and storage.
Using this calculator
- Enter your own figures in the labelled inputs. Keep the currencies, units and time periods consistent.
- Choose any applicable rate profile, pattern or assumption shown for this tool. Open additional inputs when relevant.
- Review retained fresh tonnes and available dry matter tonnes, then read the stated assumptions and eligibility conditions before using the result.
