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%|
