O presente trabalho representa uma proposta de metodologia para o levantamento integrado de unidades de terra (land units) dentro do processo de avaliação de terras (land evaluation), este trabalho adota um sistema classificatório baseado nas técnicas de campo tradicionais dos centros de pesquisa da Europa central e da Ásia. O diferencial destas técnicas é que elas incluem tópicosque permitem o monitoramento e a definição de variações temporais intra-anuais para as paisagens. As técnicas de campo foram aplicadas de forma expedita em quatro parcelas na paisagem do Maciço Residual de Poço das Trincheiras, no sertão do Estado de Alagoas. A partir dos dados obtidos foi possível estabelecer um breve reconhecimento da estrutura vertical de alguns geossistemas da área em questão e proceder sua repartição em geohorizontes, que permitiu a definição de seus estados anuais. |

Phosphate fertilization is a common practice in agriculture worldwide, and several commercial products are widely used. Triple superphosphate (TSP) is an excellent soluble phosphorus (P) source. However, its high cost of production makes the longterm use of crude rock phosphate (RP) a more attractive alternative in developing countries, albeit its influence on plant-associated microbiota remains unclear. Here, we compared long-term effects of TSP and RP fertilization on the structure of maize rhizosphere microbial community using next generation sequencing. Proteobacteria were dominant in all conditions, whereas Oxalobacteraceae (mainly Massilia and Herbaspirillum) was enriched in the RP-amended soil. Klebsiella was the second most abundant taxon in the RP-treated soil. Burkholderia sp. and Bacillus sp. were enriched in the RP-amended soil when compared to the TSP-treated soil. Regarding fungi, Glomeromycota showed highest abundance in RP-amended soils, and the main genera were Scutellospora and Racocetra. These taxa are already described as important for P solubilization/acquisition in RP-fertilized soil. Maize grown on TSP and RP-treated soil presented similar productivity, and a positive correlation was detected for P content and the microbial community of the soils. The results suggest changes of the microbial community composition associated to the type of phosphate fertilization. Whilst it is not possible to establish causality relations, our data highlights a few candidate taxa that could be involved in RP solubilization and plant growth promotion. Moreover, this can represent a shorter path for further studies aiming the isolation and validation of the taxa described here concerning P release on the soil plant system and their use as bioinoculants.
