Compost and vermicompost of urban solid waste in Licania tomentosa (Benth) seedlings production to arborization

Abstract

Compost and vermicompost, produced from organic fraction of municipal solid wastes were studied as components of potting media for Licania tomentosa ("oiti") seedlings production. The objective was to achieve data to amplify the utilization of these products, in order to utilize them to ornamental and urban arborization species. Increasing rates of organic fertilizers were used until the total soil substitution from the potting media. There were no fitotoxic effects. Compost or vermicompost caused higher germination index of seeds and higher growth of plants. The study demonstrated that it is possible to utilize these products in other activities beyond aplication in agricultural soil, and it can generate new markets to this kind of organic fertilizer.
