These farmers are asking the question, "How do you know when to stop grazing the dry medic is summer?" 

Their extension agent is going to show them a simple way to measure the pods during summer.

The sheep must not graze all the pods.

Some must remain on the field for the autumn regeneration.

You use this device to measure the pods on the ground every few days in summer.

It is a piece of cardboard with a hole cut out of the centre.

The hole is 11 cm in diameter.

This represents 1/100 of a square metre.

This disc is placed anywhere in the medic field.

Whatever pods are inside the circle are collected.

An easy way to do this is to put them in your hat.

Open up each of the pods and count the seeds.

This is important as different types of medic have different numbers of seed within each pod.

In a dry spring the number of seeds in each pod will be less.

If you can count more than 20 seeds taken from the pods you have collected within the measuring disc,  you can leave the sheep to continue grazing.

If you have less than 20 seeds in the pods you have collected in the measuring disc, you should remove the sheep and feed them on the cereal stubble or other pasture.

Repeat this operation a ten different spots on your field.

Count the seeds in the pods and take an average of all the samples.
