What it is for
Promotes a living soil, humus formation and root growth. Works in depth and strengthens soil life.
Dose and application
Amount: 100 g/ha in 25–35 L water (home garden: 10–20 g in 5–10 L per 1,000 m²). Stir rhythmically for 1 hour (alternately forming vortices, lukewarm water approx. 37 °C). Apply as soon as possible after stirring, close to the ground in large drops (brush broom, knapsack sprayer with a coarse nozzle). Late afternoon from 4–5 pm under a lightly overcast sky is ideal, late evening in hot weather. Do not spray if there is a risk of night frost. Note: no more than 3–4× per crop per year – overuse harms the storage quality of the harvest (Masson). If blocked by horn silica: as an exception, spray 500 onto the leaves.
