Results Assessment of your Silage Clamp
(Over 100) Very High Risk - Significant amounts of silage may be wasted.
(86-100) - High Risk - Likely to experience heating over much of the face.
(71 - 85) - Medium Risk - Mould may be visible towards top of clamp.
(50 - 70) - Low Risk - Heating possible in top half & shoulders of clamp.
(Under 50) - Minimal Risk - Unlikely to encounter heating during feedout.
