QR compost activator


QR (Quick return) is a 100% biological compost preparation, which is used to stimulate and speed up the process in the compost. It is used in composts in small gardens as well as large farms the world over. We have been using it for more than 40 years and have experienced a quicker and more balanced result compared to composts without QR.

After decades of experimentation during the 1920s-40s, Miss Maye E. Bruce succeeded in preparing a quick-acting herb preparation made from nettle, dandelion, camomile, valerian and yarrow plus oak bark, seaweed flour and honey.

Miss Bruce, who was an English biodynamic practitioner, was very interested in compost and tried to find a simpler way to develop and speed up thetransformation of compost and thereby increase the use of good compost among growers. 

Her preparation is very efficient, easy to use and yields first class compost surprisingly fast. We do not consider QR to be a replacement for the common biodynamic compost preparations, but an excellent alternative for those growers who do not follow the biodynamic tradition.

QR is available in portion (2g), 10g and 100g packages. 1 portion of QR is enough to treat 2 m3 of compost. Each packet contains a sheet of complete instructions in English.
