Resumo: Chemical extractors behaviors were evaluated in soils which received copper manuring, according to two essays with soybean and corn as testing plants in greenhouse. The experimental design was completely randomized with three replications. The treatment consisted of three doses of Cu (0.0, 2.5 and 5.0 mg.dm-3) used in CuSO4.5H2O solution. The extractor solutions were Mehlich 1 (HCl 0.05M+ H2SO4 0.025M), EDTA 0.005M and DTPA 0.005M-TEA at pH 7.3, so that copper contents in those soils and plants were determined by atomic absorption spectrometry. The extractors evaluation was done considering linear regression among copper contents in plants dry matter and in soils. In both cultures the DTPA 0.005M-TEA at pH 7.3 showed higher superior coefficients of correlation in relation to the other extractors, revealing itself as the best extractor to evaluate copper phytoavailability in these studied soils.

O delineamento experimental foi inteiramente casualizado com três repetições. Os tratamentos consistiram de três doses de Cu (0,0, 2,5 e 5,0 mg.dm-3), aplicadas na forma de solução de CuSO4.5H2O. As soluções extratoras utilizadas foram Mehlich 1 (HCl 0,05M + H2SO4 0,025M), EDTA 0,005M e DTPA 0,005M-TEA a pH 7,3, sendo os teores de cobre nos solos e nas plantas determinados por espectrometria de absorção atômica. A avaliação dos extratores foi realizada com base em regressão linear entre os teores de cobre na matéria seca das plantas e nos solos. Em ambas as culturas, o DTPA 0,005M-TEA a pH 7,3 apresentou coeficientes de correlação superiores aos demais extratores, revelando-se o melhor extrator para avaliar a fitodisponibilidade de cobre nos solos estudados.Universidade Estadual De Maringá2008-05-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/301910.4025/actascitechnol.v21i0.3019Acta Scientiarum.
