Although many Soil Spectral Libraries (SSLs) have been created globally, these libraries still not operationalized for end-users. To address this limitation, study an online Brazilian Service (BraSpecS). The system was based on the Library (BSSL) with samples collected in Visible–Near–Short-wave infrared (vis–NIR–SWIR) and Mid-infrared (MIR) ranges. interactive platform allows users to find spectra, act as custodians of data, estimate several soil properties classification. tested by 500 65...
The interest in new techniques to support digital soil mapping (DSM) is increasing. Numerous studies pointed out that the measure of magnetic susceptibility (MS) can be extremely useful identification properties related with factors and processes formation, applied mapping. This study addressed effectiveness identify facilitate distinction different pedogenic environments a representative hillslope highland Planalto Médio state Rio Grande do Sul (RS), Brazil. In 350-ha area municipality...
Despite optical remote sensing (and the spectral vegetation indices) contributions to digital soil-mapping studies of soil organic carbon (SOC), few have used active radar mission data like that from synthetic aperture (SAR) sensors predict SOC. Bearing in mind importance SOC mapping for agricultural, ecological, and climate interests also recently developed methods monitoring using Sentinel-1 SAR data, this work, we aimed take advantage high operationality imaging test accuracy prediction...
Selenium uptake and its content in soybean grains are affected by Se application methods. This study evaluated the impact of foliar combined with a multi-nutrient fertilizer (MNF) on soybean, establishing threshold to better understand relationship between yield two genotypes (58I60 Lança M5917). Two trials were conducted 4 × 2 factorial design: four rates (0, 10, 40, 80 g ha-1) methods (Se or not MNF). Foliar fertilizers applied twice, at phenological stages beginning pod development grain...
Spatial soil data applications require sound geospatial including coordinates and a coordinate reference system. However, when it comes to legacy we frequently find them be missing or incorrect. This paper assesses the quality of observations in Brazil, evaluates sources (survey reports, maps, spatial infrastructures, web mapping services) expert knowledge as means fix inconsistencies. The analyses included several consistency checks performed on 6,195 from Brazilian Soil Information System....
'Esmeralda' is an orange fleshed peach cultivar primarily used for juice extraction and secondarily the fresh fruit market. Fruit yield quality depend on several local environmental managerial factors, mainly nitrogen, which must be balanced with other nutrients. Similar to perennial crops, trees show carryover effects of carbohydrates nutrients stored in their tissues. The aims present study are (i) identify major sources seasonal variability qu Tree Department Federal University Pelotas...
Abstract: The objective of this work was to test the extrapolation soil-landscape relationships in a reference area (RA) topographic map (scale 1:50,000), using digital soil mapping (DSM), and compare these results those obtained similar studies previously conducted Brazil. A survey 10 km2 RA, conventional techniques 1:10,000), made order 678 physiographically 1:50,000) DSM. decision tree technique employed build predictive model based on classes eight terrain attributes RA. validation DSM...
