dc.description.resumoThe use of P extractors is significant to obtain a better efficiency in crop productivity, being important to understand which extractor is the most suitable to be used. Our objective was to evaluate the efficiency of different extractors on the recovery of available P forms in fertilizers with variable solubility. An experiment was carried out using a 2×4×18 factorial scheme, being two forms of extraction: heating or agitation; four extractors: Citric Acid pH 1.4 (AC), Acid Ammonium Citrate pH 3 (AAC pH 3), Acid Ammonium Citrate pH 5 (AAC pH 5) and Neutral Ammonium Citrate, pH 7 (NAC); and eighteen sources of P from different solubility. The experiment was carried out in a randomized block design, with three replications. To evaluate the extractive method capacity and relate them to yield of matter and P content absorbed by the crops, a test was carried out in a greenhouse, with sequential cultivation of corn (single hybrid BM 709 PRO 2) and soybean (BMX IPRO BONUS). The treatments were generated by the combination of an 8 × 2 factorial, with eight phosphate fertilizers with different solubilities (SSP, TSP, PAPR Araxá, PAPR Patos, Araxá PR, Salitre PR, Morocco PR and Daoui PR), and two doses of P ( 125 and 250 mg dm-³). The experimental design was carried out in randomized blocks, with four replications. Although there are exceptions, the combination of data demonstrates that agitation was the most effective extraction operating procedure for most P sources or extractors, and that AAC pH 3 and AAC pH 5 extractors presented similar ability to extract P, independent of the extraction procedure, except for Daoui PR shake form. In addition, the pH 3 acid ammonium citrate extractor showed a high correlation, and can be considered equal to the traditional extraction methods used to estimate the amount of P available both in natural sources and in more soluble sources, such as partially acidulated phosphate rocks and fully acidulated phosphate fertilizers.pt_BR
