“…In soils of the varying land use types, the mean pH (H2O) values ranged from 4.28-4.64 in soils formed from false-bedded sandstone and 4.27-5.57 in those derived from shale (Table 2). Abua et al (2010) and Iwara et al (2011) reported similar results in some soils of Southeastern Nigeria. From the result, soil reaction differed significantly across the parent materials and land use types which could be a consequence of composition of the lithologic material, land use practices and topography of the areas.…”

Land use and parent materials influence behaviour of soils including responsiveness to erosion forces. The study investigated some soil properties related to erodibility in Abia and Imo States of Nigeria. Soil sampling was guided by geology and land use type. Random sampling technique was adopted in field studies. Two parent materials and three land use types were chosen for the study. In each parent material, three land use types were studied and in each land use, three soil profiles were sunk, described, and sampled using FAO procedure. Soil samples were subjected to laboratory analyses and data generated were analyzed using descriptive and inferential statistical tools. Results showed that sand sized particles ranged from 533.10 to 778.80 g kg–1 and this distribution differed significantly between parent materials. Silt content ranged from 141.70 g kg–1 in soils derived from false-bedded sandstone to 202.20 g kg–1 in shale-derived soils. Clay-sized particles ranged from 77.30 g kg–1 in soils derived from false-bedded sandstone to 264.70 g kg–1 in shale-derived soils, respectively. Water-stable aggregate ranged from 19.38% in false-bedded sandstone to 29.23% in shale-derived soils. The DR (dispersion ratio) mean values ranged between 4.26 in shale and 8.46 in false-bedded sandstone, while the CDI (clay dispersion index) mean values ranged between 2.17 in shale and 8.41 in false-bedded sandstone, respectively. The forest soils had the lowest values of both DR (6.89) and CDI (6.40) for soils of the false-bedded sandstone, 3.85 and 1.59 for those derived from shale. The clay flocculation index (CFI) had mean of 2.16 in false-bedded sandstone and 7.83 in shale. In soils of the varying land use types, the mean soil pH (H2O) ranged from 4.28 to 4.64 in soils derived from false-bedded sandstone and 4.27-5.57 in those derived from Shale. From the results, parent material and land use influenced soil erodibility parameters (water-stable aggregates, mean-weight diameter, DR, CDI, and CFI) and other soil properties such as organic carbon, bulk density, and moisture content.

“…Enzymes and easily accessible minerals are indicators of healthy soil maintained by the structure of the microbial community, and these microorganisms are crucial to soil biological activities( Page-Dumroese et al, 2021 ). The compositional variation of microbial communities among different locations reflects the adaptability of native communities and the effects of different plant species, weather, and root exudates to some extent ( Lauber et al, 2008 ; Yang et al, 2010 ; Anderson, 2011 ; Iwara et al, 2011 ; Lladó et al, 2017 ).…”

In dry deciduous tropical forests, both seasons (winter and summer) offer habitats that are essential ecologically. How these seasonal changes affect soil properties and microbial communities is not yet fully understood. This study aimed to investigate the influence of seasonal fluctuations on soil characteristics and microbial populations. The soil moisture content dramatically increases in the summer. However, the soil pH only gradually shifts from acidic to slightly neutral. During the summer, electrical conductivity (EC) values range from 0.62 to 1.03 ds m-1, in contrast to their decline in the winter. The levels of soil macronutrients and micronutrients increase during the summer, as does the quantity of soil organic carbon (SOC). A two-way ANOVA analysis reveals limited impacts of seasonal fluctuations and specific geographic locations on the amounts of accessible nitrogen (N) and phosphorus (P). Moreover, dehydrogenase, nitrate reductase, and urease activities rise in the summer, while chitinase, protease, and acid phosphatase activities are more pronounced in the winter. The soil microbes were identified in both seasons through 16S rRNA and ITS (Internal Transcribed Spacer) gene sequencing. Results revealed Proteobacteria and Ascomycota as predominant bacterial and fungal phyla. However, Bacillus, Pseudomonas, and Burkholderia are dominant bacterial genera, and Aspergillus, Alternaria, and Trichoderma are dominant fungal genera in the forest soil samples. Dominant bacterial and fungal genera may play a role in essential ecosystem services such as soil health management and nutrient cycling. In both seasons, clear relationships exist between soil properties, including pH, moisture, iron (Fe), zinc (Zn), and microbial diversity. Enzymatic activities and microbial shift relate positively with soil parameters. This study highlights robust soil-microbial interactions that persist mainly in the top layers of tropical dry deciduous forests in the summer and winter seasons. It provides insights into the responses of soil-microbial communities to seasonal changes, advancing our understanding of ecosystem dynamics and biodiversity preservation.

“…The comparatively low TN content in grassland soil may be attributed to low amount of litter returned to the soil. Bokhtiar & Sakurai [46] stated that organic carbon, total N, and available P contents in the soil tend to increase to a large extent with the increase in organic matter (derived from dead leaves, stems and branches or tree biomass).…”

A sustainable university has been defined as a higher educational institution that addresses, involves and promotes the minimization of negative environmental, economic, societal, and health effects generated in the use of their resources in order to fulfil its functions of teaching, research, outreach and partnership, and stewardship in ways to help society make the transition to sustainable lifestyles. Earlier studies on green innovations have basically centered on the environmental benefits and were purely descriptive in nature. Several others examined the effect of green innovation on soil organic carbon by comparing street trees of species. The present study would contribute to literature using a mixed research approach to empirically investigate the contributions of green innovation on carbon storage and perceived environmental quality in Lagos State University, Nigeria. Data for the study were obtained by collecting 100 surface (0 – 15cm) soil samples with the aid of a soil auger under campus trees, grasses, ornamental trees and vegetables (Amaranthus and green vegetable farms) across different land uses on campus. Also, data on green characteristics (tree height, tree size, canopy cover, density of herbs, basal cover and herbaceous cover) were measured using different ecological procedures, while 655 questionnaire copies were administered to staff and students to ascertain their perceived environmental quality of green innovation. Data obtained were analyzed using averages, simple percentages, One-Way Analysis of Variance, multiple regression analysis and principal components analysis. The results obtained showed that carbon storage significantly varied among the green innovation components with canopy cover contributing over 55% of carbon storage. The study revealed that canopy cover and tree size substantially contributed in carbon storage with canopy cover being more effective. PCA result identified beautification of LASU (19.8%), flood control (18.8%), promotion of urban ecology (15.8%) and improvement in air quality (9.5%) as the principal dimensions or perceived environmental quality of green innovation. The result further showed that green innovation characteristics have significant relationship with carbon storage. The study shows the importance of campus tree in carbon reduction and recommends the need for universities to give necessary recognition and incorporate these green components in physical planning.
