What it is for
Soil activator after Maria Thun. Stimulates decomposition and soil life, harmonises the soil. Especially after ploughing up, after harvest or on tired soils.
Dose and application
Amount: 240 g/ha in 35–50 L of lukewarm water (home garden: 60 g in 10 L per 1,000 m²). Stir for only 20 minutes (not 1 hour!). Remains effective for at least 72 hours after stirring – one stirring can be used on 3 consecutive evenings. Spray close to the ground in large drops, in the evening on moist soil. Best results with 3 regular sprayings (Masson). Especially effective on chalky/blocked soils, after harvest with a lot of crop residue, for sheet composting and as a compost starter for farmyard manure. Can also be used as an activator for liquid manure/slurry.
