The pH of such soil ranges between 8.5 and 10. The high ESP and low ECe of soil cause de-flocculation of soil aggregates and hence decrease their permeability to water (Chesworth, 2007). Likewise, the FAO-UNESCO soil classification system was established as a map legend for the 1:5 ...
problem in the digital mapping of categorical soil variables and soil types is the imbalanced number of observations, which leads to reduced accuracy and the loss of the minority class (the class with a significantly lower number of observations compared to other classes) in the final map. So...
biome groups although the profile numbers vary among biome types (Supplementary Fig.1). The profiles also cover various climate conditions across the globe with mean annual temperature (MAT) ranging from –20.0 to 30.7 °C and mean annual precipitation (MAP) ranging from 0 to 6,674 mm...
To explore the intraspecific genomic diversity of the SMAG, we generated 107 pangenomes for 2200 SGBs with >10 high-quality MAGs by clustering protein sequences from all conspecific genomes at 90% amino acid identity, which was used to define a “core” genome13. Open pangenomes have larger ...
(C) In the correlation map C(x0, x;t) with x0 = 14 mm, only one direction of propagation emerged from the refocusing field. (D) Sonogram of the liver region. The interface between the abdominal muscles and the liver is visible around z = 12 mm. (E) The passive shear-wave-speed...
boreal regions (seeRelevant subjectbelow for details) using, as a basis, the evidence identified within a recently completed systematic map [35,36]. This systematic map aimed to collate evidence relating to the impacts of all agricultural management on soil organic carbon in boreo-temperate regions...
Progress in monitoring and modelling or forecasting these types of degradation is also shown. Soils of drylands, the Arctic and all man-made soils are hotspots of chemical and biological degradation. As chemical and biological degradation processes in the microscale are lingering and interacting, ...
For each soil class, the impact of the land use types cropland, grassland and forest on SOC stocks were compared. SOC stocks Fig. 1. Map of Bavaria with classes of mean annual temperature (MAT) and location of the sampling points. ...
