“…Some studies have reported the effect of organic waste as manure and biosolids on agricultural soils, which may increase the concentration of some metals and cause environmental contamination [1,2]. Since metals can accumulate in the upper layers of the soil, toxic levels to plants and animals can be reached and also impair water quality [3,4,5,6].…”

Aims/Objectives: An agricultural tropical soil treated and untreated with swine manure was evaluated to Pb 2+ , Cu 2+ , Zn 2+ , and Ni 2+ competitive sorption dynamics. Study Design: Metal ion mobility patterns were evaluated by sorption-desorption reactions with the mineral and organic matter soil phases. Place and Duration of Study: Agronomic Institute of Parana (IAPAR) at Londrina city, ParanaState, Southern Brazil, in an experiment conducted since June 2008. Methodology: Soybean and corn were growing up in the experimental area in summer and winter, respectively. Swine manure (SM) was applied twice a year, and the amount was calculated according each crop necessity. Experiments were in batch, varying the metal ion concentration from 1.0 to 10 meq L −1 . After equilibrium, the solid phase was analyzed by EDXRF and liquid phase by ICP-OES. Metal ion mobility was evaluated by applying the dual-mode Langmuir-Freundlich mathematical model, in addition to rate removal and Gibb's free energy determination. Results: Sorption capacity increased after the SM amendment, and the retention sequence Pb 2+ >Cu 2+ >Zn 2+ >Ni 2+ was observed. The sorption capacity increased in 30%, 45%, 176%, and 231% for Pb 2+ , Cu 2+ , Zn 2+ , and Ni 2+ , respectively. The relative intensity of the fluorescence emission lines showed metal ion sorption increased after the amendment, keeping the same sequence observed for the adjustable parameters from the fitting by dual-mode Langmuir-Freundlich model. Conclusion: The possibility of a controlled release of micronutrients, considering low-affinity sorption sites, brings an excellent look to the swine manure amendment.

A B S T R A C TThis study investigated the residual effects of pig slurry (PS) applied to common carpet grass pasture (Axonopus affinis) for two years (September 2008-March 2010 on dry matter yield and forage-nitrogen uptake from October 2010-May 2011. A field experiment was conducted in a randomized complete block design with four replications. The treatments were 102, 204, 306, 408, and 510 m 3 ha -1 pig slurry applied for two years; one mineral nitrogen rate (1,250 kg ha -1 ammonium nitrate) for two years; and no nitrogen fertilization (control). The pasture was cut at intervals of 48, 34, 43 and 69 days, which corresponded to 266, 300, 343, and 412 days after the last fertilizer application, respectively. Dry matter yield increased by 398 kg ha -1 for each 100 m 3 of PS applied, the equivalent of 317 and 564 kg ha -1 for each 100 kg ha -1 of inorganic and organic N applied, respectively. The residual effect of PS on dry matter yield and forage-nitrogen uptake ranged from 11-45% and 8-40%, respectively, indicating a gradual release and availability of N in PS, which can help reduce the amounts of nitrogen applied to pasture.Efeito residual de dejeto líquido de suínos em pastagem de grama-tapete comum R E S U M O Verificou-se, neste estudo, o efeito residual de dejeto líquido de suíno aplicado em pastagem de grama-tapete comum (Axonopus affinis) durante dois anos (setembro 2008 a março 2010), por meio da avaliação da produção de matéria seca e da absorção do nitrogênio na forragem, no período subsequente (outubro 2010 a maio 2011). Um experimento no campo foi realizado em delineamento de blocos completos casualizados, com quatro repetições. Os tratamentos foram cinco doses de dejeto (102, 204, 306, 408 e 510 m 3 ha -1 por dois anos), ausência de adubação nitrogenada (tratamento-controle) e uma dose de nitrogênio mineral (1.250 kg ha -1 de nitrato de amônio, por dois anos). A pastagem foi cortada em intervalos de 48, 34, 43 e 69 dias, que corresponderam a 266, 300, 343 e 412 dias após a última aplicação dos fertilizantes, respectivamente. A taxa de produção de matéria seca aumentou em 398 kg ha -1 para cada 100 m 3 do dejeto de suínos previamente aplicados, equivalente a 317 e 564 kg ha -1 para cada 100 kg ha -1 da forma inorgânica ou orgânica de nitrogênio, respectivamente. O efeito residual do dejeto líquido de suínos na produção de matéria seca variou de 11 a 45% e na absorção do nitrogênio da forragem variou de 8 a 40%, indicando liberação gradual ou disponibilidade do N no dejeto, o que contribuiria para a redução das quantidades de nitrogênio a serem aplicadas na pastagem. 375Residual effect of pig slurry on common carpet grass pasture R.
