In this video you will be shown by youtube user "WOS ONE", how to identify weed cutted with PK13/14. For this purpose, some weed is placed in water. After some hours the water will be overcooked and dissolves fertilizer. As residue remain various salts and residues of PK13/14 fertilizer.
We completely overhauled streckmittelmelder.de, renamed it to dirty-weed.com and ported it to different countries and languages. For each country there are now maps with warnings. In addition, statistics are now available and weed prices can also be reported and shown.
