Clear as compost

I’ve been overwhelmed recently trying to research good, affordable composts. There are websites where people are raising the issue of aminopyralids from animal manure or green waste making their way into bought composts, and manufacturers not admitting it happens. Some composts contain large amounts of green waste compost, despite their claims to only have carefully sourced wood chip.

It would be great if you could do a compost comparison that details the ingredients and trials the growth of peas, beans and tomatoes, which are most affected by undetectable amounts of aminopyralids. There’s also the issue of composts calling themselves organic, when they mean containing organic matter.

We say: We are hoping to start a long-term compost trial later this year.
