Resumo: | Agronomic phosphate source performance is dependent on its compositions, soil properties, plant species and microorganisms such as mycorrhizae. A greenhouse experiment, at the University of Santa Maria, RS, Brazil, was carried out to evaluate the agronomic efficiency of three different sources of phosphates in a typic paleudult soil, in a randomized 3 x 2 x 2 factorial design with four repetitions: (a) three phosphates (coarse granulated magnesium thermophosphate – MT, concentrated superphosphate – CS, and mixture of both – MI; (b) soil with and without liming; and (c) with and without G. clarum inoculation. The residual effects using samples of the same soil priorly cultivated with sorghum and the same experimental design were also estimated. The performing decreasing order in furnishing phosphorus of the sources was: CS, MI and MT. The inoculation with G. clarum promoted phosphorus recovery increase of MI and MT, but did not increase it when compared with CS, and the residual effect of MI was similar to CS. Inoculation promoted 29% dry matter yield in the first sowing and 34% as residual effect |

O presente trabalho tem o objetivo de avaliar a ação de micorrizas na eficiência agronômica de diferentes fontes de fósforo. Conduziu-se um experimento em vasos e em casa de vegetação, na Universidade Federal de Santa Maria, RS, Brasil, com amostras de argissolo vermelho distrófico arênico. Os tratamentos constituíram um fatorial 3x2x2, em delineamento experimental inteiramente casualizado, com quatro repetições: (a) com e sem presença de calagem, (b) três fontes de fósforo (termofosfato magnesiano de granulometria grosseira (TER), superfosfato triplo (SFT) e mistura desses fosfatos (MIS) e (c) com e sem inoculação com Glomus clarum. Estimou-se o efeito residual empregando amostras do mesmo solo cultivado anteriormente com sorgo forrageiro e usando os mesmos tratamentos. Cultivou-se o capim-pensacola até o pleno florescimento. Verificou-se que o TER apresentou menor eficiência que o STF e o MIS, tanto no efeito imediato quanto no residual, por causa da sua menor solubilidade. A inoculação com G. clarum aumentou a recuperação do fósforo adicionado ao solo de todos os fosfatos, mas não modificou a relação de equivalência com o SFT; também promoveu a produção de massa seca em 29% no efeito imediato e 34% no efeito residualUniversidade Estadual de Maringá2008-05-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/286010.4025/actasciagron.v22i0.2860Acta Scientiarum.
