Testing manure 1. Thoroughly mix 1 part manure with 1 part multi-purpose compost in a clean bucket. Prepare enough to fill four 5-inch pots. 2. Fill another four clean pots solely with multi-purpose compost. These will be the untreated comparisons. 3. Place each of the pots in a separate saucer to prevent water from one pot reaching another. 4. Water the pots and leave to stand for 24 hours. 5. Plant each pot with four broad bean seeds. 6. Observe subsequent growth for a four-week period and note any ill effects in the pots containing the manure mix, such as cupped leaves and fernlike growth on new shoots.

I thought Dow said aminophyralid would not spread in water.
