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%
