A system for processing a manure sludge includes in a preferred embodiment: (a) an anaerobic digester; (b) a drying bed planted with a plurality of macrophytes, said macrophytes being nurtured so they are growing and engaging in evapotranspiration bed; and (c) a transfer assembly adapted to deliver a manure sludge from the anaerobic digester to the drying bed so that the roots of the plants contact manure sludge transferred to the drying bed so that the sludge is dried by evapotranspiration. The anaerobic digester and transfer assembly are adapted to: (i) treat raw farm waste slurry to provide a biostabilized manure sludge composition; and (ii) deliver the biostabilized manure sludge composition to the drying bed at a solids content of at least about 1% by weight.
