ALONSO, Francisco et al. Response of chrysanthemum plant to addition of broiler manure as a substitute for commercial substrate. Rev. Int. Contam. Ambient [online]. 2012, vol.28, n.3, pp.259-263. ISSN 0188-4999.

Two different broiler manure types mixed with bedding material (straw and sawdust) were added at rates of 0 and 10% to two commercial peat substrates (black peat and sphagnum peat) to study the chrysanthemum plant growth. In all cases, the quality and size of the plants was better with the mixtures of black peat substrates. The number of flowers per plant increased significantly with the mixtures of black peat with broiler manure, but the size of the plants did not improve. The addition of broiler manure to sphagnum peat improved significantly the studied growth parameters, because substrate pH was more suitable for cultivation. There was no plant mortality with the mixtures tested, but when the percentage of broiler manure in the substrate mixture increased the plant mortality was remarkable.
