The bulk volume comprises a volume of soil solids and pore spaces.…”

This work aimed to analyze the soil quality and heavy metal contamination in the Jumar watershed of Jharkhand and suggests possible measures that could be taken to guarantee suitable management practices. Therefore, in the present work, the soil sampling was done at 8 locations, selected based on site visit. The GPS coordinates of the sampling sites were noted. The soil samples were collected during pre-monsoon and post-monsoon seasons for 2017 and 2018 at a depth of 20 cm from the top. Water samples were collected from the river flowing closer to the sampling points. Then, soil quality parameters such as pH; electrical conductivity; bulk density; moisture content; and surface water quality parameters such as pH, EC, TDS, DO, COD, BOD, alkalinity, turbidity, and nutrients (N & P) were studied. For heavy metal analysis (Pb, Zn, Cu, As, Ni), both soil and water samples were analyzed using an inductive coupled plasma-optical emission spectrophotometer (ICP-OES). Statistical tools like descriptive statistics, multivariate analysis, principal component analysis, correlation coefficient, and ANOVA were applied using SPSS version 21. The data indicate that the values of moisture content varied between 22.06 and 45.7%, soil bulk density varied between 1.20 and 1.55 g/cm 3 , pH varied between 7.79 and 8.17, and EC varied between 116.66 and 207.08 μS/cm. The concentrations of heavy metals in the pre-monsoon season were higher (Zn 0.183 mg/l, Cu 0.09 mg/l, Ni 0.061 mg/l) than those in the post-monsoon season (Zn 0.17 mg/l, Cu 0.076 mg/l, Ni 0.138 mg/l). The water quality index found using pH, EC, TDS, DO, COD, BOD, alkalinity, turbidity, BOD, COD, nutrients, and heavy metals indicated that most sites had excellent water quality, especially in the pre-monsoon period. But in the post-monsoon period of 2017, the water quality index showed that water was in poor condition. Overall water quality was found to be good. It was found that the soil had very slight traces of heavy metals and was slightly alkaline indicating the need for better watershed management practices for the future. PCA showed that the component variables like pH and EC were principal components specially for both pre-monsoon seasons, whereas through ANOVA, it was found that the variable has strong relationship among themselves.

“…Higher bulk density was found in open mixed sal forest compared to closed mixed sal forest (Table 1) this is due to the greater organic matter deposition on the oor of closed forest while in open forest less accumulation of organic matter was observed. The organic matter acts as a sponge, increases pore spaces, and reduces the bulk density (Hamza and Anderson 2005;Agbeshie et al, 2020). Furthermore, anthropogenic activities and intensive gazing signi cantly affect the bulk density (Jhariya & Singh, 2021;Oraon et al, 2018;Shah et al, 2017).…”

Change in forest cover and forest loss greatly impact the physicochemical and microbiological properties of the soil. Mixed Sal forests have a significant impact on soil qualities, favourably affecting the amount of organic matter, the availability of nutrients, and the pH levels. So therefore, our hypothesis was to check the status, seasonal variations and vertical distribution of soil physiochemical and microbial soil properties under closed mixed sal forest (no human activities) and open mixed sal forest (human interferences). The data revealed that closed mixed sal forest were higher (p < 0.05) in soil moisture (41.5%), clay particles (36.5%), soil organic carbon (28.6%), available nitrogen (5%), available phosphorus (25%), available potassium (12%) and SOC stocks (23.5%), respectively over open mixed sal forest. Soil organic carbon stock (SOC stock) ranged 5.7 to 24.5 Mg ha− 1. Closed mixed sal forest had 43% higher SOC stock in the surface soil (D1:0-20cm)), 22–60% in subsurface to deeper soil profile (D2:20-40cm-D5:80-100cm). The SMBC content ranged 12.0 to 591µg C g− 1 irrespective of forest type and seasons. Closed mixed sal forest had 60% higher (p < 0.05) SMBC in D1 than the open mixed sal forest while it reduced with depth and 17.1 to 56.7% higher SMBC in the subsurface to bottom most soil profile (D2-D5). The SMBC content was higher in the Monsoon period ranged 48.2 to 591µg C g− 1 in closed mixed sal forest and 44.8 to 326.4 µg C g− 1 in open mixed sal forest. The SMBC reduced 24.2 to 45.1% in the post monsoon period while the reduction was more intense in the pre monsoon period (48.1 to 68.2%) compared to the monsoon period under the closed mixed sal forest. Similarly, the decline was more intense in the open mixed sal forest, where SMBC declined 12.1 to 54% in the post monsoon and 56.1 to 76.2% in pre monsoon period compared to the monsoon period. So, therefore, we conclude here that the study shows that human interferences in the mixed sal forests often leads to the loss of forest cover and may also have significant negative impact on the physicochemical and microbiological properties of soil, ultimately reducing soil fertility.
