“…Manganese was strongly and positively correlated with Zinc(r=0.232) and positively with SAR (r=0.011) and ESP (r=0.009). Zinc was negatively correlated with SAR and ESP while SAR was strongly and positively correlated with ESP (r=0.998).Similar result was also obtained by Vijayakumar et al [10], Singh et al [12].…”

A study entitled Study of soil fertility status in KVK farm Shahjahanpur, Uttar Pradesh, India was carried out during 2020-21. Soil Samples collected from different depths viz. 0-15 (Surface), 15-30 cm (Subsurface) were processed and analyzed for chemical properties. Soil pH, EC and OC ranged from 8.13-8.73, 0.20-0.28 and 0.41-0.76 at surface and all the samplers belongs to moderately alkaline to strongly alkaline range. Soils of KVK, Shahjahanpur classified based on pH, EC ( 1:2.5 soil: water ratio), and OC were low to medium, majority of soils falls under low EC and low to medium organic carbon, the available nitrogen of samples was in the range of 201.19 to 287.84 kg ha-1and were in low nutrient index range (1.38 NI), the available phosphorus of samples range between 16.34 to 21.67 kg ha-1for and falls in medium nutrient index range (2NI) while the available potassium of samples range between 357.54 to 484.98 kg ha-1 and falls in high nutrient index range (2.67 NI) where correlation acted positive in many of the cases. The soils of KVK, Shahjahanpur were categorized into low-medium-high (LMH) category based on available N, P and K concentrations. Ca/Mg ratio of the study area varied from 1.99-2.01 while Mg/K ratio varied from 1.20 to 2.26. Soils of study area were found in sufficient range for available Cu, Zn and Mn except of (Fe) Iron range found in marginal to sufficient. In these range of available nutrients wheat, rice, maize, fodder crops, pulses and some vegetables can be grown very well.

“…The height of enzymatic activity is one of the most significant indicators of the characteristics and the quality of a soil [9]. Therefore, determining the relationship between enzymatic activities and external factors can provide significant benefits in many areasfrom soil reclamation to the increase in productivity.…”

“…In the case of vermicompost, most of the degraded properties were highly correlated with other properties, except for WHC. Similarly, Singh et al (2017) reported that vermicompost effectively promoted soils’ fertility and microbial factors [ 81 ]. The poor correlation of WHC might be caused by a stronger tendency of aggregation of vermicompost, i.e., vermicompost was not well dispersed in the soil, and its effect in improving WHC was diminished, despite its contribution to improving the SOM content ( Figure 1 a and Figure S5a ).…”

Revitalization of Total Petroleum Hydrocarbon Contaminated Soil Remediated by Landfarming

Soil health deteriorates through the contamination and remediation processes, resulting in the limitation of the reuse and recycling of the remediated soils. Therefore, soil health should be recovered for the intended purposes of reuse and recycling. This study aimed to evaluate the applicability and effectiveness of several amendments to revitalize total petroleum hydrocarbon contaminated soils remediated by the landfarming process. Ten inorganic, organic, and biological amendments were investigated for their dosage and duration, and nine physicochemical, four fertility, and seven microbial (soil enzyme activity) factors were compared before and after the treatment of amendments. Finally, the extent of recovery was quantitatively estimated, and the significance of results was confirmed with statistical methods, such as simple regression and correlation analyses assisted by principal component analysis. The landfarming process is considered a somewhat environmentally friendly remediation technology to minimize the adverse effect on soil quality, but four soil properties—such as water holding capacity (WHC), exchangeable potassium (Ex. K), nitrate-nitrogen (NO3-N), available phosphorus (Av. P), and urease—were confirmed to deteriorate through the landfarming process. The WHC was better improved by organic agents, such as peat moss, biochar, and compost. Zeolite was evaluated as the most effective material for improving Ex. K content. The vermicompost showed the highest efficacy in recovering the NO3-N content of the remediated soil. Chlorella, vermicompost, and compost were investigated for their ability to enhance urease activity effectively. Although each additive showed different effectiveness according to different soil properties, their effect on overall soil properties should be considered for cost-effectiveness and practical implementation. Their overall effect was evaluated using statistical methods, and the results showed that compost, chlorella, and vermicompost were the most relevant amendments for rehabilitating the overall health of the remediated soil for the reuse and/or recycling of agricultural purposes. This study highlighted how to practically improve the health of remediated soils for the reuse and recycling of agricultural purposes.
