Improving the quality of the soil in our orchard or garden is without a doubt something that all amateur and not so amateur gardeners want. With a double deck drum composter this can be achieved.
And also, by doing so, you are going to make your compost natural and free of toxic chemical compounds. You can build the device with your own hands and it will in turn allow the compost to be much easier to do, since it will make the decomposition process much faster.
If you are interested in this project, here you have the complete instructions, it is in English, but the images are very indicative.
