Resumo: | The Mehlich extractor has been used at the School of Agronomy of the U.F.G., in the State of Goiás since 1966. Therefore, some laboratories which operate in the “Cerrado” regions are beginning to use the Anion Exchange Resin Method. This experiment compared the two extractors, using three different sources of phosphorus; natural powdered phosphate (FN), hyperphosphate (H), and triple superphosphate (ST) in doses of 0, 200, 400 and 600 Kg of P2O5, per hectare. The two extractors showed a correlation for these sources of phosphate. However the results differed because of the two responses. Between the zero dose of P2O5, per hectare, of natural phosphate, the Mehlich extractor extracted 685.2% more for a production increase of soybeans of only 20.6%. At the same time, the resin method extracted only 81.26% more for the same phosphate variation. Changing the quantity of P2O5, from 0 to 600 kg per hectare of triple superphosphate, production increase in soybeans was 40.3% which corresponded to an increase of 316.6% in extraction using the amin exchange resin method and 241.9% using the Mehlich Method. It was concluded that the resin method was more efficient because it manifested a better correlation in superphosphate, but costly because it extracted less natural phosphate. |

O extrato Mehlich vem sendo usado no Estado de Goiás, desde 1966, pela Escola de Agronomia da Universidade Federal de Goiás. No entanto, alguns laboratórios que atuam na região dos cerrados estão passando a usar também o método da resina trocadora de ânions. Neste experimento, compararam-se os dois extratores usando-se três diferentes fontes de fósforo: fosfato natural finamente moído (FN), hiperfosfato (H) e superfosfato triplo (ST), nas doses de 0, 200, 400 e 600 kg de P2O5 total por hectare. Os dois extratores apresentaram correlação para estas fontes de fósforo, mas os comportamentos foram diferenciados ao se considerar as grandezas de respostas. Entre a dose zero de P2O5, e a dose máxima de 600kg de P2O5, por ha, de fosfato natural, o extrator Mehlich extraiu 685% a mais de P contra uma aumento de produção de soja de somente 21%. Já a resina extraiu 81% a mais de P para a mesma variação de fosfato. Variando a quantidade de P2O5, de 0 a 600 kg/ha com superfosfato triplo o aumento na produção de soja foi de 40%, correspondente a um aumento de extração de P pela resina de 317%.Escola de Agronomia - Universidade Federal de Goiás2007-12-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/2605Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 21-22, n. 1, Jan./Dec. 1991-1992; 93-100Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 21-22, n. 1, jan./dez. 1991-1992; 93-100Pesquisa Agropecuária Tropical; v. 21-22, n. 1, jan./dez. 1991-1992; 93-1001983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/2605/2587Almeida Neto, José Xavier deBorges, Luiz Carlos ValladaresChaves, Lázaro Joséinfo:eu-repo/semantics/openAccess2009-06-16T20:33:51Zoai:ojs.revistas.ufg.br:article/2605Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:17.515553Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
