Translations:Lessive à la cendre/34/en

The large majority of detergents used are based on products containing sodium as the active agent, which once released into the environment is not only alkalinising (increases the pH) but also salinising in the long term. One of the great advantages of ash detergents is that the active ingredient is potash (the ionic form of potassium, the K in the famous N-P-K tryptic of agricultural fertilisation). Even if the discharge from your washing water continues to be alkalinising, it will fertilise your environment with an element that is often forgotten by gardeners and is harder to provide than nitrogen !
