Digital soil class mapping in Brazil: a systematic review

Abstract: In Brazil several digital soil class mapping studies were carried out from 2006 onwards to maximize the use of existing maps and information and to provide estimates for wider areas. However, there is no consensus on which methods have produced superior results in the predictive value of soil maps. This study conducts a systematic review of digital soil class mapping in Brazil and aims to analyze the factors which can improve the accuracy of digital soil class maps. Data from 334 digital soil class mapping stu… Show more

“…The mapping of land suitability for specific purposes (e.g. agriculture) has become a very useful tool for land management in recent decades (Coelho et al, 2021). In fact, its assessment has gained a great deal of interest worldwide and it is specifically related to global priorities such as sustainable development goals (Ahamed et al, 2020).…”

“…Canoco 5 was employed to perform NMDS analysis based on OTU data of different samples, and they were visualized by OriginPro 2019. The alpha diversity of different materials in the aerobic composting process was visualized by the 'vioplot' package in R. Kruskal-Wallis tests were used to determine whether there were differences in alpha diversity among multiple materials (Coelho et al, 2021). Permutation multivariate analysis of variance (PERMANOVA) was calculated by the 'vegan' package of R software.…”
