The squeeze test
The squeeze test can be used to estimate the drymatter percentage of fresh grass. Cut the grass into 2 - 3 cm lengths, roll it into a ball about twice the size of a golf ball and squeeze it in your fist for 30 seconds. The table below gives approximate drymatter percentages.
| Table 1: Estimating pasture drymatter levels4 | |
|---|---|
| Estimated drymatter % | |
| Juice runs out easily | 18 - 20% |
| A little juice runs out with difficulty | 20 - 25% |
| Your hand is damp and the sample stays in a ball when you stop squeezing | 25 - 30% |
| Sample does not stay in a tight ball when you stop squeezing | Over 30% |
