The field is not the feed trough

The story

Eddie studies separate pictures of a tank and a field with Amina on the bio plant visitor terrace.

At the bio plant, Eddie spotted a route on Amina’s pictures that led from the tank to a field.

For grown-ups: The sealed tank has two separate routes out. One takes biogas to suitable energy equipment. The other takes digestate through checks before it is used as a suitable fertiliser on a field.

At the farm, Eddie holds a field picture and asks Fiona a question, with nothing offered to eat.

At the farm, Eddie asked Fiona a question. Was the stuff from that route going to be Hamish’s dinner?

Fiona: “Hamish gets the right feed, Eddie. A useful leftover still needs the right destination.”

On the bio plant visitor terrace, Amina explains separate output pictures to Fiona.

Amina explained the two branches to Fiona. One gives biogas for energy equipment. The other gives digestate, which is checked to make sure it is a suitable fertiliser.

Fiona looks at tall grass, holding a small photo of earlier professional work on the field.

Fiona looked over her field. Professionals had used the fertiliser there earlier, and since then the grass had had time to grow.

Hamish grazes in a ready field while Fiona watches from outside the closed gate.

Now the field was ready. Hamish grazed happily while Fiona kept watch from the gate.

Hamish: (thinking) “Grass. Excellent choice.”

Fiona points to growing grass while Eddie listens, and Hamish stays in a separate paddock.

Fiona showed Eddie the difference. The fertiliser helps the soil, the soil helps the grass grow, and the grass is Hamish’s lunch.

For grown-ups: These are three separate things. The fertiliser helps care for the soil. The grass grows over time. The cow eats the grass, never the fertiliser.

The real-life bit

Digestate from a bio plant is checked before it can be used as a suitable fertiliser, and it is kept separate from biogas, which goes to energy equipment. It is for the soil, never for animals to eat, and household scraps should never be fed to farm animals. The farmer decides when a field is ready to graze; there is no fixed number of days. Gullbrae is made up. Your council’s own rules are the ones to follow.
