Resumo: The use of composted urban waste as a source of nutrients in agriculture is an economic alternative for discarding this material. However, due to the diversity of materials that compose this waste, long term studies on its effects on soil chemical attributes and crop yield are necessary. This study aimed at evaluating the potential of urban waste compost (UWC) as a fertilizer for sunflower and maize crops, as well as its effects on the chemical attributes of an Oxisol. A field experiment, with UWC doses of 0 Mg ha-1, 10 Mg ha-1, 20 Mg ha-1, 30 Mg ha-1 and 40 Mg ha-1 and mineral fertilization according to the recommendation for each crop, was carried out. The results showed an increase in soil pH from 6 to 6.5, with the UWC application. The soil potential acidity decreased linearly from 3.0 cmolc dm-3 to 2.4 cmolc dm-3, contributing to the SMP index increase, what reflected on the increase of the soil cation exchange capacity. The bases saturation increased from 77% to 85%, mainly due to the increase in calcium and magnesium levels. The use of UWC resulted in sunflower grain yield similar to that for mineral fertilization, at 10 Mg ha-1, 20 Mg ha-1 and 30 Mg ha-1, being significantly higher at 40 Mg ha-1. The maize grain yield at or above 20 Mg ha-1 of UWC did not differ from the mineral fertilization. The UWC presented potential to replace the mineral fertilization for sunflower and maize crops.

Todavia, devido à diversidade dos materiais que compõem estes resíduos, há a necessidade de estudos constantes sobre os efeitos de sua utilização nas propriedades químicas do solo e na produtividade das culturas. Objetivou-se avaliar o potencial fertilizante de um composto de lixo urbano (CLU) nas culturas de girassol e milho e seu efeito nas propriedades químicas de um Latossolo Vermelho. Realizou-se experimento de campo com tratamentos compostos por doses de 0 Mg ha-1, 10 Mg ha-1, 20 Mg ha-1, 30 Mg ha-1 e 40 Mg ha-1 de CLU e adubação mineral conforme a recomendação de cada cultura. Os resultados indicaram aumento no pH do solo de 6 para 6,5, com a adição do CLU. A acidez potencial do solo diminuiu linearmente de 3,0 cmolc dm-3 para 2,4 cmolc dm-3, contribuindo para o acréscimo no índice SMP, o que refletiu no aumento da capacidade de troca de cátions do solo. A saturação por bases aumentou de 77% para 85%, devido, principalmente, ao acréscimo nos teores de cálcio e magnésio. O CLU proporcionou produtividade de grãos de girassol semelhante à da adubação mineral, nas doses de 10 Mg ha-1, 20 Mg ha-1 e 30 Mg ha-1, sendo que, na dose de 40 Mg ha-1, foi significativamente superior. A produtividade de grãos de milho em doses iguais ou superiores a 20 Mg ha-1 de CLU não diferiu da adubação mineral. O CLU apresentou potencial fertilizante, podendo substituir a adubação mineral nas culturas de girassol e milho.Escola de Agronomia - Universidade Federal de Goiás2013-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Experimentalapplication/pdfhttps://revistas.ufg.br/pat/article/view/23079Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 43, n. 3, Jul./Sep. 2013; 278-285Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 43, n. 3, jul./set. 2013; 278-285Pesquisa Agropecuária Tropical; v. 43, n. 3, jul./set. 2013; 278-2851983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/23079/15262Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessStrojaki, Tiago ViniciosSilva, Vanderlei Rodrigues daSomavilla, AndréDa Ros, Clovis OrlandoMoraes, Moacir Tuzzin de2020-07-10T12:33:05Zoai:ojs.revistas.ufg.br:article/23079Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:00.623344Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
