Resumo: Urban waste compost has a potential to be used as an organic fertilizer in agriculture, but field studies are required to define the recommendable rates for crops. This study aimed at evaluating the effect of fertilization with urban waste compost on the soil chemical properties, yield, nutrient and heavy metal contents, in maize leaves and grains. The field experiment was carried out in a randomized complete block design, with seven treatments and four replications. The treatments consisted of six urban waste compost doses (0 Mg ha-1, 5 Mg ha-1, 10 Mg ha-1, 20 Mg ha-1, 30 Mg ha-1 and 40 Mg ha-1), applied in the planting furrow, plus an additional control treatment, with NPK mineral fertilization and no waste compost application. Fertilization with up to 40 Mg ha-1 of urban waste compost improves soil fertility. Fertilization with urban waste compost increases grain yield and the N, P and K contents in leaf tissue and maize grains, without inducing plant contamination with heavy metals. The application of 30 Mg ha-1 of urban waste compost can replace mineral fertilization in maize cultivation.

Objetivou-se avaliar o efeito da adubação com composto de lixo urbano nos atributos químicos do solo, produtividade, teores de nutrientes e de metais pesados, nas folhas e grãos de milho. O experimento foi realizado a campo, empregando-se delineamento experimental em blocos ao acaso, com sete tratamentos e quatro repetições. Os tratamentos foram constituídos por seis doses de composto de lixo urbano (0 Mg ha-1, 5 Mg ha-1, 10 Mg ha-1, 20 Mg ha-1, 30 Mg ha-1 e 40 Mg ha-1), aplicadas no sulco de semeadura, além de um tratamento adicional, com adubação mineral NPK e sem adubação com composto de lixo. A aplicação de até 40 Mg ha-1 de composto de lixo urbano melhora as condições de fertilidade do solo. A adubação com composto de lixo urbano aumenta a produtividade de grãos e os teores de N, P e K no tecido foliar e nos grãos de milho, sem provocar contaminação da planta com metais pesados. A aplicação de 30 Mg ha-1 de composto de lixo urbano pode substituir a adubação mineral, em cultivo de milho.Escola de Agronomia - Universidade Federal de Goiás2017-07-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/45475Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 47, n. 2, Apr./Jun. 2017; 186-194Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 47, n. 2, abr./jun. 2017; 186-194Pesquisa Agropecuária Tropical; v. 47, n. 2, abr./jun. 2017; 186-1941983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/45475/23372Copyright (c) 2017 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessMantovani, José RicardoSpadon, Fernando2020-07-13T18:36:57Zoai:ojs.revistas.ufg.br:article/45475Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:16.537627Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
