When faeces are stored in the absence of moisture (i.e. urine) they dehydrate into a crumbly, white-beige coarse, flaky material or powder. Dehydration means that the moisture naturally present in the faeces evaporates and/or is absorbed by the addition of adrying material (e.g. ash, sawdust, lime).
None of the options were relevant for Application of dehydrated faeces.
