Fósforo (P) é um nutriente-chave para o estabelecimento de consórcio de gramíneas e leguminosas forrageiras. O objetivo deste trabalho foi determinar a necessidade de P para o estabelecimento de capim-braquiarão e amendoim forrageiro cultivados em associação sob condições controladas. Um experimento de vasos foi conduzido em casa de vegetação usando o delineamento em blocos completos ao acaso com oito tratamentos e quatro repetições. Os tratamentos foram as seguintes doses de P: 0 mg dm-3 (controle), 80 mg dm-3, 160 mg dm-3, 240 mg dm-3, 320 mg dm-3, 400 mg dm-3 e 560 mg dm-3 [fonte: Ca(H2PO4)2.H2O]. Capim-braquiarão (Urochloa brizantha 'Marandu') e amendoim forrageiro (Arachis pintoi 'BRS Mandobi') foram cultivados por 24 dias depois do corte de uniformização e então cortados a 10 cm de altura para determinação da matéria seca do topo da planta. O suprimento adequado de P para o crescimento do topo da planta diferiu entre as espécies. Capim-braquiarão necessitou de 80 mg dm-3 de P, ao passo que 160 mg dm-3 de P foram exigidos pelo amendoim forrageiro. O amendoim forrageiro necessitou de mais P do que o capim-braquiarão para o estabelecimento de ambas as espécies cultivadas em associação sob condições controladas. |

The Atlantic Forest is the most threatened Brazilian biome, with less than 10% of its original surface cover remaining. Thus, several programs of payment for ecosystem services have been developed in this biome focusing on revegetation of degraded areas. Forest regeneration promotes the development of soil invertebrate communities that play an important role in soil processes, delivering a wide range of ecosystem services. We studied the changes in macrofauna communities in three forests under different regeneration stages and the relationship between these invertebrates and soil chemical and physical properties. Macrofauna and soil chemical and physical properties were sampled until 30 cm depth in three forest fragments of the Brazilian Atlantic Forest under different regeneration stages: young regenerating forest (~8 years old), secondary forest in intermediate regeneration stage (~20 years old) and native secondary forest fragment. No significant differences in saturated hydraulic conductivity (Ks) were observed among sites, however, the old native forest showed reduction in Ks in deeper layers compared to young regenerating forests. Several macrofauna taxa were positively correlated with Ks and soil carbon. The stage of regeneration modified the abundance and diversity of these invertebrates in general (except for earthworms), and the old native forest showed high abundance of most taxa. In conclusion, our study highlights the potential of macrofauna communities as robust indicators of soil functions re-establishment in regenerating forests within the Atlantic Forest biome. The observed positive correlations between macrofauna abundance and diversity with soil water infiltration and organic carbon content emphasize the key role of these invertebrates to essential ecosystem functions.
