Opis:
This study aimed to investigate the mineralogy, moisture retention, and the compressive response of two agricultural soils from South West Nigeria. Undisturbed soil cores at the A and B horizons were collected and used in chemical and hydrophysical characterization and confined compression test. X-ray diffractograms of oriented fine clay fractions were also obtained. Our results indicate the prevalence of kaolinite minerals relating to the weathering process in these tropical soils. Moisture retention by the core samples was typically low with pre-compression stress values ranging from50 to 300 kPa at both sites. Analyses of the shape of the compression curves highlight the influence of soil moisture in shifts from the bi-linear to S-shaped models. Statistical homogeneity test of the load bearing capacity parameters showed that the soil mineralogy influences the response to loading by these soils. These observations provide a physical basis for the previous classification series of the soils in the studied area. We showed that the internal strength attributes of the soil could be inferred from the mineralogical properties and stress history. This could assist in decisions on sustainable mechanization in a datapoor environment.

Opis:
The hydrophysical properties of the prevalent Humic Latosols (organic matter rich and charcoal stained soils) were related to structural sustainability under loading. Intact cores collected at the Ap, AB, Bw horizons were used for hydrophysical characterization. Precompression stresses at 10 suctions were obtained to estimate the load bearing capacities. We observed the dominance of kaolinite with some occurrences of gibbsite and hydroxy-interlayered vermiculite in the clay mineralogy. The high organic matter content in the Ap horizon favours crumb structure with the structural unit presenting high porosity and water retention. The structure of the AB and Bw horizons was, however, granular with structural units having low porosity. Possible influence of earlier incidences of fire enhanced the organic matter and carbon content in the soil reducing down the profile from 42.5 g kg-1 at the Ap to 16.4 g kg-1 at the Bw horizon. The C/N ratio increased from 14 at the Ap to 17 at the Bw, and air capacity increased from 18.1% at Ap to 32.0% at Bw. Precompression stress values were: 100.6±40.7 kPa at Ap, 117.4±44.6 kPa at AB, and 116.1±58.9 kPa at Bw. Load bearing capacities at the AB and Bw horizons were homogenous.

Opis:
The influence of the physical and chemical composition of corn distillers dried grains with solubles on its flowability was evaluated in the current study. The samples were evaluated for angle of repose, compressibility, Hausner ratio, tapped density, bulk density, mean bulk density, colour and nutrient content. PROC CORR and REG procedures were used to determine correlations. The ether extract was negatively correlated with crude protein and redness (a*), while crude protein was negatively correlated with yellowness (b*). Acid detergent fibre and neutral detergent fibre were negatively correlated with a* and positively correlated with lightness (L*), respectively. Compressibility showed a negative correlation with bulk density. Bulk density, tapped density and mean bulk density did not impact the angle of repose. The angle of repose was positively correlated with the compressibility and Hausner ratio. Apart from the correlation between acid detergent fibre and tapped density, the angle of repose and other physical parameters were not affected by the nutrient composition of the distillers dried grains with solubles samples. In conclusion, the results of this study indicate that nutrient composition has little influence over the flowability of distillers dried grains with solubles but compressibility and the Hausner ratio can be used to predict the potential flow characteristics of corn distillers dried grains with solubles.
