Resumo: The composting process of urban waste with several P sources was monitored until maturation of the compost. The experiment was laid out in a randomized block design with four replications and five treatments: a) pure urban waste (UW), b) UW with araxá rock phosphate (UW + ARP), c) UW with patos de minas rock phosphate (UW + PRP), d) UW with ARP and ammonium sulphate (UW + ARF + AS) and UW with triple superphosphate (UW + TS). Heaps with 600 kg of fresh UW were incubated in open field after mixing throughly, according to treatment with 10,6 kg P2O5 and 5,3 kg N per UW ton. The heaps were mixed and the temperature, moisture, pH and C/N ratio were determined many limes during the 91 days of the composting process. At the final sampling, available and total P content were determined. One extraction of P using the exchange resin method showed no increase in available P from ARP or PRP after the composting process. The addition of AS also did not increase the availability of P from ARP. There was no effect of ARP and PRP on the temperature, moisture, pH and C/N ratio during composting, while the TS and AS affected the pH when compared with pure UW.

O experimento foi realizado em blocos, ao acaso, com quatro repetições e cinco tratamentos: a) lixo urbano puro (L); b) L mais fosfato natural de Araxá (L + FNA); c) L mais fosfato natural de Patos de Minas (L + FNP); d) L mais FNA mais sulfato de amônio (L + FNA + SA); e) L mais superfosfato triplo (L + ST). Foram formadas leiras de lixo fresco a céu aberto. De acordo com o delineamento experimental, fez-se a mistura de 10,6kg de P2O5 e 5,3kg de N por tonelada de lixo. O processo de compostagem durou 91 dias, ao longo dos quais realizou-se, periodicamente, o revolvimento das leiras e a medição da temperatura, umidade, pH e relação C/N. Após a compostagem, determinou-se o P total e o P disponível. Não houve aumento de P disponível no composto tratado com FNA ou FNP, segundo determinações realizadas pelo método da resina em urna só extração. A mistura do L com FNA e SA também não favoreceu a solubilização do FNA. Não se observou nenhum efeito do FNA ou FNP sobre a temperatura, umidade, pH e relação C/N durante a compostagem. O ST e o SA diminuíram sensivelmente o pH, porém não alteraram os outros parâmetros, quando comparados ao lixo puroPesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPeixoto, Ricardo Trippia dos G.Almeida, Dejair Lopes deFranco, Avilio Antonio2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15833Pesquisa Agropecuaria Brasileira; v.24, n.5, maio 1989; 599-606Pesquisa Agropecuária Brasileira; v.24, n.5, maio 1989; 599-6061678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15833/9903info:eu-repo/semantics/openAccess2014-08-26T19:05:38Zoai:ojs.seer.sct.embrapa.br:article/15833Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-26T19:05:38Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
