Test results of compost

To find the best barrel barrels on the market, we tested a selection of barrels at different prices, with the cheapest costing only £ 24.

There was a big difference in our composting box, which is best and worst. With an impressive overall rating of 79%, the best compost barrel received five stars for composition, composting utilization and yield. But for our bottom container, it was a whole other story. If you get only 41% of the total rating, you will be disappointed to pay more than £ 100 for this particular model.

How we test compost

For testing, we have selected compost baskets, which are the most common types for sale.

We used three containers for each product and arranged them in three separate blocks so that no container of the same type was tightly joined.

To fill the containers, we collected soft green and brown material and mixed it thoroughly in a ratio of 50:50. Each container was filled to half its capacity in April 2019. It was then filled with enough material each month to reach a quarter of its capacity. The filling was stopped in September 2019, held again in April 2020 and the process ended at the end of July 2020.

The contents were turned (or stirred as it was not easy to empty the containers) twice in the first year of July and September and once in the second year in late June and the compost was dried when dried out. The amount of compost that had settled and was beginning to rot was assessed and a temperature inspection was carried out every two months.
