Effects of the transition from dry forest to pasture on bacterial communities and chemical properties in soils in Northeastern Brazil

"Soil Chemistry and Enzymes" is a dataset captured from soils from the 0-10 cm layer of pastures and forests of three municipalities located in the Microregion of Garanhuns, Pernambuco state (Northeast Brazil): Brejão (8°59'39.95"S; 36°32'22.69" W), Garanhuns (8°58'27.25"S; 36°27'8.12"W) and São João (8°48'35.77"S; 36°24'25.19"W). This study evaluated the transition from dry forest (FO) to pastures in a varied productive state, one with less activity (PA) and another more productive (PB). This pasture state was defined based on the Normalized Difference Vegetation Index (NDVI), calculated from images from the Multispectral and Panchromatic Wide-Scan Camera (WPM) of the CBERS 4A satellite (L4) (INPE - Brazil). The "CBERS_4A_WPM_BAND0-4" files represent the cropped images for the study area. Chemical and enzymatic characteristics of the soils are noted in the "Soil Chemistry and Enzymes.xlsx" file. The raw gene sequences from the 16S rRNA gene library (bacteria) were also made available in the "16S_rRNA.rar" file. The library was constructed from genomic DNA extracted from the 0-10 cm soil layer and sequencing was performed on the Illumina MiSeq platform (300 bp paired-end).“土壤化学与酶活性（Soil Chemistry and Enzymes）”数据集采集自巴西东北部伯南布哥州加拉纽斯微区内三个市镇的牧场与森林0~10 cm土层土壤样品，三个市镇分别为布雷饶（Brejão，8°59'39.95"S; 36°32'22.69"W）、加拉纽斯（Garanhuns，8°58'27.25"S; 36°27'8.12"W）与圣若昂（São João，8°48'35.77"S; 36°24'25.19"W）。本研究评估了旱生森林（FO）向不同生产状态牧场的转变：一类为低活性牧场（PA），另一类为高生产性牧场（PB）。牧场状态基于归一化差异植被指数（Normalized Difference Vegetation Index, NDVI）确定，该指数由中国巴西地球资源卫星4A（CBERS 4A）卫星L4载荷的多光谱全色宽幅相机（Multispectral and Panchromatic Wide-Scan Camera, WPM）影像计算得到（巴西国家空间研究院INPE）。"CBERS_4A_WPM_BAND0-4"文件为研究区裁剪后的影像数据。土壤的化学与酶活性特征记录于"Soil Chemistry and Enzymes.xlsx"文件中。细菌16S rRNA基因文库的原始基因序列已上传至"16S_rRNA.rar"文件，该文库由0~10 cm土层土壤提取的基因组DNA构建，测序工作基于Illumina MiSeq平台完成（300 bp双端测序）。
