Changes in the global water cycle affect irrigation requirements and soil processes as well as the structure of soil microbial communities and function and the carbon (C) balance. The microbial structure and C sequestration under land use changing scenarios are rarely studied in the semi-arid region of Brazil. Here, we assessed the effects of land-use changes (irrigation and cultivation) on C storage in the soil and the structure of total bacteria (16S rRNA gene profile) and fungus (18S rRNA gene profile) at soil depth. We evaluated two soil profiles in the semi-arid region in northeastern Brazil. Profile P1 in an area with long-term irrigation (1,500 mm of water per year) and cultivation (small-scale farming systems, mainly with subsistence crops, which is a frequent land use system in the region of irrigated soil) for about 26 years. Profile P2 under natural conditions with 400 mm of water per year of rainfall (rain-fed hyperxerophilic Caatinga). Land-use changes showed a small influence on C storage; however, the changes strongly affected the soil organic matter (SOM) quality as well as the bacterial and fungal community structure, indicated by higher contents of labile-C and microbial biomass along with lower C-CO2 emission. The relatively large amounts of aliphatic groups in the soil surface and subsurface in the cropped system (P1) suggested enrichment of methylene structures and probable increase of microbial-derived compounds. Methoxylic and aromatic groups tend to increase at depth (Bt horizon) indicating that the subsoil C responds to soil management changes. The structures of the bacterial community are distinct at depth in P1 and more similar at depth in P2. On the other hand, the structures of the fungal communities are more similar at depth in P1 than in P2. Furthermore, the irrigated agriculture also presented a carbon management index greater than 140% in most horizons, indicating that the soil management system did not cause soil degradation.

RESUMO: A região oeste da Bahia se destaca por sua atividade de larga escala, utilizando tecnologia avançada, proporcionando altos rendimentos de soja, milho e algodão, sendo considerada a maior produtora de grãos do Nordeste brasileiro. O objetivo deste estudo é disponibilizar informações sobre o desenvolvimento do aplicativo (app) MonitoraOeste, desenvolvido pela Embrapa Territorial, para produtores do oeste da Bahia. Nesse aplicativo, são disponibilizadas informações sobre a dinâmica da vegetação natural e das culturas irrigadas ao longo do ciclo da cultura, como Evapotranspiração (ET), biomassa (BIO), produtividade da água (PA) e NDVI (Normalized Difference Vegetation Index), visando acompanhar a dinâmica da vegetação natural e culturas irrigadas ao longo do ciclo agrícola, e disponibilizar essas informações de maneira rápida e prática aos produtores do oeste da Bahia, através de aplicativo mobile (app) , disponibilizado em sistema Android e IOS. A metodologia utilizada foi o algoritmo SAFER (Simple Algorithm For Evapotranspiration Retrieving) para obtenção de indicadores agrometeorológicos espectrais. Para a aplicação do modelo são necessários dados de estações meteorológicas, disponibilizados pelo INMET, e imagens do satélite MODIS, com resolução espacial de 250m e temporal de 16 dias. ABSTRACT: The western region of Bahia is characterized by its large-scale activity, using advanced technology, providing high yields of soybeans, corn and cotton, being considered the largest grain producer in the Brazilian Northeast. The objective of this study is to provide information about the development of the mobile app (app) MonitoraOeste, developed by Embrapa Territorial, for producers in western Bahia. This application provides information on the dynamics of natural vegetation and irrigated crops throughout the crop cycle, such as Evapotranspiration (ET), biomass (BIO), water productivity (PA) and NDVI (Normalized Difference Vegetation Index), aiming monitor the dynamics of natural vegetation and irrigated crops throughout the agricultural cycle, and make these available information fast and practice to producers in western Bahia, through a mobile app, available on Android and IOS systems. The methodology used was the SAFER algorithm (Simple Algorithm For Evapotranspiration Retrieving) to obtain spectral agrometeorological indicators. For the application of the model, data from meteorological stations, available by INMET, and images from the MODIS satellite, with a spatial resolution of 250m and a temporal resolution of 16 days.
