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.

Essential oils of medicinal plants show potential to control phytopathogens. Essential oils of Lippia sidoides Cham, Lippia lasiocalycina Cham, Lippia origanoides Kunth - Teresina, Lippia origanoides Kunth - Jatobá, Mesosphaerum suaveolens (L.) Kuntze, Croton sonderianus Muell. Arg. And Croton zehntneri Pax et Hoffm. were evaluated regarding their chemical composition and in controlling the Sclerotium rolfsii Sacc. The experiments were carried out in a completely randomized design with five concentrations and the control (without oil application): 0.0313; 0.0625; 0.1250; 0.2500 and 0.500 mL kg-1 in Petri dishes with PDA medium (potato-dextrose-agar). The evaluations consisted of daily measurements of the colony diameter in diametrically opposite directions, 24 h after the experiment installation and maintained until the radial reach of the colony on the edges of the Petri dish, in one of the treatments. The chemical composition of the essential oils were evaluated by GC-MS and the following compounds were identified: Thymol (33.5%, L. sidoides); piperitenone oxide (67.7%, L. lasiocalicyna); borneol (19.2%, L. origanoides); borneol carvacrol (34.4%, L. origanoides ? Jatobá); sabiene (30.3%, M. suaveolens); β-sabinene (30.5%, C. sonderianus); and estragole (90,1%, C. zehntneri). The S. rolfsii fungus is highly sensitive to L. sidoides, L. origanoides - Jatobá and C. zehntneri essential oils, suggesting its use in the management of Sclerotium wilt in cowpea. |
