“…The diminished crude protein levels in the SP suggest that availability of N to the plants waned during the grain filling stage (i.e., later in the growing season), which did not occur in the other soils. Soil biological activity plays a major role in regulating plant available N, and both the SP and TD initially had greatly diminished urease activity, ammonium oxidation, and potentially mineralizable N (O'Brien et al., ). Since TD did not show reduced crop protein, the lower values in SP were likely the result of the increased PHCs.…”

Crop production on heavily disturbed soils following crude oil remediation

Cropland contaminated by crude oil typically requires remediation before it can meet pre‐contaminated productivity potentials. Remediation strategies focus on removing the contaminant, but they also often alter soil properties, which affects the capacity of the land to sustain agricultural production. This research describes crop production following the remediation of crude oil contaminated soil in North Dakota, USA using two different strategies, a modified land‐farming technique and ex situ thermal desorption. Wheat (Triticum aestivum L.) and field pea (Pisum sativum L.) were grown in soils treated by both of those techniques, as well as mixtures of each treated soil with native topsoil. Across three growing seasons of comparisons to native topsoil, crop production was 61 ± 20% lower in the modified land‐farm soils and 52 ± 25% lower in thermal desorption‐treated soils; these yield declines were likely associated with reduced soil organic carbon levels. Notably, the soil mixtures had higher soil organic carbon levels and matched the native topsoil in both yield and protein content, suggesting that soil mixing may be a promising tool in cropland soil reclamation. Overall, these findings reinforce that crop production on reclaimed land is linked with soil properties, so long‐term reclamation success requires a holistic approach to soil management.

“…In this paper, soil remediation describes the process of removing or stabilizing contaminants from soil, while reclamation involves the process of replacing remediated soil and returning the land to natural or economical productivity. Numerous soil remediation strategies exist to reclaim soil after contamination such as digging and hauling to a landfill, landfarming, and thermal desorption (TD) (Bekele et al., 2015; O'Brien et al., 2016; O'Brien, DeSutter, Ritter, et al., 2017; Green et al., 2020), all which risk or exacerbate topsoil loss. Overall, the remediation and reclamation methods used, and inherent soil characteristics, will influence the time and cost to recover soil ecosystem function and land productivity.…”

The effects of thermal desorption (TD) on soil physical and chemical properties after crude oil contamination are recently well studied. However, there are limited field‐scale studies on long‐term soil biological property recovery such as microbial communities and plant growth, which are vital for meeting global agrosystem demands and restoring ecosystem health. This study describes the status of soil biological properties after 4 yr of crop production on oil‐contaminated cropland remediated via TD and a modified land farming technique. Plots were constructed in 2015 with native, uncontaminated topsoil (A); TD‐treated subsoil (TDU); untreated land‐farmed subsoil (SP); TDU + A (TDA), and SP + A (SPA) where soil ratios were 1:1 by volume, and composted manure (CM) was applied at 40 Mg ha‐1. After 3 yr of crop production (2019) grain sorghum [Sorghum bicolor (L.) Moench] was planted. Soil microbial community characteristics were assessed through phospholipid fatty acid analysis and by estimating mycorrhizal root colonization. Notably, inherent soil chemical and physical properties influenced the recovery of microbial communities in remediated soils. However, sorghum biomass production in TDU was 50 ± 9% greater than SP while the microbial abundance in these treatments remained similar. Mycorrhizal colonization variation likely reflected rhizosphere nutrient scarcity and not the interactions of either remediation strategy. Based on these results after 4 yr of cropping, TDU does not diminish soil microbial recovery, and when possible, blending TDU materials with topsoil provides the greatest level of recovery relative to topsoil only.

“…However, in this case, the issue of minimizing the negative impact of the operating oil sludge ponds, as well as the need to remove additional territories from economic circulation on the territory of placement of new oil sludge tanks [Pashkevich et al 2019]. Thus, it can be assumed that the most expedient way to reduce the negative impact of the sludge ponds on the atmosphere and return the territory of the sludge ponds to economic circulation is the disposal of the stored and newly formed oil sludge and the reclamation of the sludge ponds [O'Brien et al 2017].…”

At present, monitoring of air pollution near industrial facilities is one of the most urgent tasks. Its implementation is a requirement of Article 42 of the Constitution of the Russian Federation and the basis for the ecological wellbeing of the population. This problem is especially critical for the production facilities located within residential areas or in close proximity to them. The scientific article presents the results of a monitoring study of the air pollution in a residential area exposed to the negative impact of the storage of primary oil refining waste. Within the frames of the scientific research, the analysis of the stock materials of the enterprise was conducted; field observation was performed on the territory of the considered enterprise and the construction of ecological cartographic models was carried out, reflecting the level of the air pollution in the territory under consideration. The study also carried out a literary review and presented a list of the main existing technologies for the utilization of oil sludge to improve the quality of the air in the region under consideration.
