Copy numbers of 16S rRNA gene determined by qPCR were more than three orders of magnitude higher than the copies of ITS fragments (Table S1). Three-way ANOVA of 16S rRNA gene copy numbers revealed a significant effect of Texture and Depth, while the ITS copy numbers did not differ significa...
A soil texture is considered one of the main factors in gully erosion87. We used data and guidelines provided by the World Soil Information Service (WoSIS,http://soilgrids.org) to prepare the soil layer in the ArcGIS 10.8. The SoilGrids map is a global digital soil mapping system that empl...
CSI is in the form of a linear function of indices which effectiveness is determined by their correlation coefficient with grain yield. According to our results, using CSI, the identified rice drought-tolerant lines were in high agreement with those obtained by other methods, demonstrating that ...
This multi-functionality of soils is also addressed when soil quality is defined from an environmental perspective as “the capacity of the soil to promote the growth of plants, protect watersheds by regulating the infiltration and partitioning of precipitation, and prevent water and air pollution ...
【例句】A typical filtered accelerogram and its double integrated displacements are given as an example and a comparison with the unfiltered ac-celerogram and its respective displacements is al-so made.作为实例,给出了一个典型的经过滤波的 (地震)加速度曲线和一个通过二次积分算得的位移曲线,且和未经...
In this study the soil texture is expressed by silt plus clay (S + C) or clay (C). The relations between the soil texture and MBD, and between soil texture and critical water content (CWC—soil water at which MBD is attained) were determined. Selected soils range from 10 to 74% of...
or weakly alkaline soils, phosphorus forms complexes with aluminium, iron or calcium, which reduces the amount of phosphorus available for uptake by the crop, limiting the availability of phosphorus. And the soil itself is low in nutrients at this time and has not built up an effective ...
These garnet hornblendites have a metamorphic porphyritic texture with no significant evidence of metasomatism or assimilation, and mainly comprise amphibole, plagioclase, garnet, amphibole, and accessory minerals including rutile, ilmenite (Fig. 4E). About 0.8 vol% sulfide is contained in these ...
Variance (σ2) is a measure of how far a set of observations deviates from its average value. Thus, it represents a measure of uniformity degree. In this study, the variance of dry density was used as an index of sample uniformity. Variance was calculated according to the equation: ...
(MP) is similar to those observed in the study conducted by Kim et al.37. The Firmicutes did not respond significantly to each of the samples as did Proteobacteria, Actinobacteria, and Acidobacteria. The dominance of Proteobacteria in both heavily polluted and unpolluted soils accounts for the ...
