Services, through the action of soil microorganisms. The increased demand for food, energy, and cattle activityhas led to the conversion of natural grasslands to cultivated systems. However, the consequences of this con-version for soil microbial diversity and ecosystem functioning are yet to be discovered. Here, we used the 16 SrRNA amplicon sequencing and a large set of soil and environmental variables to understand the possible effectsof natural grasslands to cultivated pasture conversion on the soil microbial structure, composition, diversity, andfunctions. The study areas followed a gradient of increasing soil disturbance intensity, as follows: Naturalgrassland (NG), Improved-natural grassland (IG), Perennial-cultivated pasture (PP), and Annual-cultivatedpasture (AP). Natural grassland conversion to managed and cultivated pastures decreased the abundances ofAcidobacteria and Verrucomicrobia, while increased α-, γ-, and δ-Proteobacteria, Gemmatimonadetes, Bacter-oidetes, Patescibacteria, and Latescibacteria. The predicted functional profiles have also changed, as functionslike ?cellulolytic and symbionts/parasites? decreased after natural to cultivated pastures conversion, while ?ni-trogen respiration?, ?sulfur respiration?, and ?aromatic compound degradation? functions increased. Abovegroundplant diversity decrease influenced belowground microbial diversity. The main drivers of diversity, composition,and functional potential are associated with soil attributes affected by liming, like aluminum complexation. Inconclusion, we have found taxonomic and functional differences between natural and managed grasslands (NGand IG, respectively) and cultivated pastures (PP and AP), with consequences for management strategies andbiodiversity conservation priorities.

Results of soil and land evaluation survey and mapping, which were expected to be essential to rural land use and management planning, most of the time are not adequately used by their potential users and rarely reach the decision makers. This may re fl ect the poor communication between the main actors of the rural land use planning process and inappropriate language of the presented results. When fol-lowing traditional methods, there is a risk that questions may be answered that have no relevance and/or those questions may not be answered properly according to the community expectation. Therefore, it is important to change the strategies of com-munication and language of the results to make information more useful to the deci-sion makers. In this context, the objective of this work was to test a participatory soil survey and land evaluation methodology to make the information more useful and consequently more used by the decision makers. This work shows the results obtained up to now in Barra Bonita municipality, Santa Catarina State, southern Brazil. The study started with meetings, interviews and questionnaires with local community, and the main demands for information raised were the need for area expansion and management improvement of pastures for milk production. But, instead of giving them information showing soil types with technical language and a general informa-tion about land evaluation, the presented information shows what they want to know, namely, spatial location of potential new areas for pasture, what pasture type is better for different conditions and what management is recommended for each area. In the final stage of the study, participants positively evaluated the presented information.
