Soil is vital to food security and ecosystem nutrient recycling. Rapid infrastructure development projects requiring mineral resource extraction have led to an overall decrease in soil quality. Due to a higher environmental footprint, cities' soil quality has declined quickly, which requires continuous monitoring and evaluation. Educational institutions are traditionally not taken into account for such monitoring. Thus, the present study investigated the soil health status under 10 different plantations in Maharshi Dayanand University located in Rohtak city. Using different digital and volumetric methods, 20 physicochemical parameters and nutrients viz. sand, silt, clay, pH, electrical conductivity (EC), organic matter (OM), macronutrients and micronutrients. Sampling was performed at four depths (0-10, 10.1-20, 20.1-30 and 30.1-40 cm) to collect 40 samples. Repeated measures of one-way analysis of variance (ANOVA) and pairwise comparison were used to detect significant differences. Different tree plantations affected soil parameters significantly (p<0.05). The soil nutrient index value (SNIV) classified sand (3), pH (2.62), Ca2+ (2.82), Cu (2.60) and Fe (2.65) in the high fertility class. Network analysis demonstrated an effect of physicochemical parameters on OM and nutrients. The structural stability index (SSI) appropriated 50 % of the samples as thoroughly degraded (SSI<5 %). Principal component analysis (PCA) produced five significant components and designated N, P, Cu and OM as the most critical soil chemistry variables. Hierarchical cluster analysis (HCA) produced 3 clusters for tree species with similar soil properties. Overall, the campus's soil is alkaline, non-saline and nutrient deficient, and surface layers are more fertile. The soil under F. virens is the most productive. The results obtained and customized solutions provided in this article may help to improve soil health on the campus ans aid in sustainable soil use, conservation and management. This may also motivate other campuses around the globe to assess their soil health status.

Soils are a potentially viable sink for atmospheric carbon and could contribute to mitigating global climate change. Soil Organic Carbon (SOC) content exhibits considerable spatial variability both horizontally (land use) and vertically (soil profile). Land cover land use (LCLU) is one of the key determinants of SOC stock, hence there is a significant variation of SOC across different LCLUs. This study aimed to investigate the spatial variability of SOC across different LCLUs in the Greater Gaborone region of Botswana. Remotely sensed data used for image classification was obtained from the United States Geological Survey (USGS) Earth Explorer (www.usgs.gov). The imagery used in this study was Sentinel-2A obtained in the month of March with cloud content of less than 10% for easy interpretation. Image classification was done using a supervised classification method based on a Maximum Likelihood classifier. The major LCLU types identified in the area included water bodies, trees dominated, cropland, shrubland, bare land, and built-up. The Walkley and Black method, core method, Bouyoucos hydrometric method and pH meter were used to determine SOC content, bulk density, soil texture and pH, respectively. Soil bulk density, pH and sand fraction showed a negative correlation with SOC content, while silt and clay showed a positive correlation. The total SOC stock in the study area was estimated to be 4.36 MtC, with trees dominated areas accounting for 1.13 MtC (25.9%), shrubland 2.83 MtC (64.9%), cropland 0.14 MtC (3.2%), built-up 0.22 MtC (5.1%), and bare land 0.04 MtC (0.9%), hence indicating that trees dominated and shrubland were good sequesters of carbon in the Greater Gaborone.
