Maps of the sub-Saharan African showing the sites from which soils were extracted for this study and pie chart representing the distribution of samples according to the sampled countries. Sampled sites in the map are represented by dots which are colored according to the country of origin Full ...
(2017). This database was used to develop a new triangular chart so that it can be a better indicator of behavior of problematic soils, and it included case records of cone penetrometer tests carried out in problematic soils in 54 sites. Additionally, through the analysis of a database ...

Two wavelengths representing particle size arrangement and clay content at 1.7 渭m and 2.2 渭m, respectively, were used to generate a dynamic chart of the crust formation. Soil mineralogy was found to be a major factor in the crust formation. In the clayey soils, two identical stages were...

The soil collected from S1, S2 and S3 appeared to have a silty texture, while the soil from S4 and S5 had a silt loam texture according to the United State system Malvern Mastersizer 2000 particle size analyzer. The pH of all of the soil samples was slightly alkaline, ranging from 8.45 ...
Soil quality is assayed (i) qualitatively, for instance, visually by using the Munsell color chart where darker soils with high organic matter are considered of superior quality or (ii) quantitatively by measuring the soil physical, chemical, and biological attributes (de Paul Obade and Lal2013,...
How do you use a soil triangle chart? To use a soil texture triangle, follow the lines that relate with the composition of particle observed. Where these lines intersect is the soil type in question. Who invented the soil texture triangle? The first soil texture triangle was developed by Mil...
