Elimination of phytotoxicity during co-composting of spent pig-manure sawdust litter and pig sludge
(Elsevier, 1998-07-01)
A plant seed germination technique was used to assess the phytotoxicity of spent pig litter-sludge at different stages of composting in forced-aerated piles on the relative seed germination, relative root elongation, and ...
Composting of spent pig litter in turned and forced-aerated piles
(Elsevier, 1998-08-13)
