“…The soil enzymes are perceived as reliable soil quality indicators [ 17 , 75 , 76 ]. They are used to construct models for the assessment of potential soil fertility [ 28 , 77 , 78 , 79 , 80 ]. Due to their ability to signalize changes triggered under the pressure of stress factors, they also perfectly mirror the effects of pollutants on soil [ 81 , 82 , 83 ].…”

The pollution of arable lands and water with petroleum-derived products is still a valid problem, mainly due the extensive works aimed to improve their production technology to reduce fuel consumption and protect engines. An example of the upgraded fuels is the BP 98 unleaded petrol with Active technology. A pot experiment was carried out in which Eutric Cambisol soil was polluted with petrol to determine its effect on the microbiological and biochemical properties of this soil. Analyses were carried out to determine soil microbiome composition—with the incubation and metagenomic methods, the activity of seven enzymes, and cocksfoot effect on hydrocarbon degradation. The following indices were determined: colony development index (CD); ecophysiological diversity index (EP); index of cocksfoot effect on soil microorganisms and enzymes (IFG); index of petrol effect on soil microorganisms and enzymes (IFP); index of the resistance of microorganisms, enzymes, and cocksfoot to soil pollution with petrol (RS); Shannon–Weaver’s index of bacterial taxa diversity (H); and Shannon–Weaver’s index of hydrocarbon degradation (IDH). The soil pollution with petrol was found to increase population numbers of bacteria and fungi, and Protebacteria phylum abundance as well as to decrease the abundance of Actinobacteria and Acidobacteria phyla. The cultivation of cocksfoot on the petrol-polluted soil had an especially beneficial effect mainly on the bacteria belonging to the Ramlibacter, Pseudoxanthomonas, Mycoplana, and Sphingobium genera. The least susceptible to the soil pollution with petrol and cocksfoot cultivation were the bacteria of the following genera: Kaistobacter, Rhodoplanes, Bacillus, Streptomyces, Paenibacillus, Phenylobacterium, and Terracoccus. Cocksfoot proved effective in the phytoremediation of petrol-polluted soil, as it accelerated hydrocarbon degradation and increased the genetic diversity of bacteria. It additionally enhanced the activities of soil enzymes.

“…The MDSs were selected from each PC with the highest loading or correlation to the PC. According to Volchko et al (2014), as discussed by Klimkowicz-Pawlas et al (2019), "the concentration of contaminants for SQI assessment is rather insufficient"; however, it contributed to the overall SQI of the two agricultural areas. Nevertheless, mercury was seen to deteriorate soil microbial activity, which could alter nutrient cycling in the soil, thus its negative impact on the soil quality (Müller et al 2001), as well as its significant contribution to the SQI.…”

“…The soil quality index (SQI) was used to describe the soil quality of both agricultural areas, which was used extensively by authors, especially when anthropogenic influences were involved (Fernández et al 2020;Klimkowicz-Pawlas et al 2019;Li et al 2018;Masto et al 2015;Vasu et al 2016). The principal component analysis (PCA) was used as the method for soil indicator selection or the minimum data set (MDS) to reduce the number of indicators or parameters into significant or highly correlated to the principal components avoiding redundancy (Stefanoski et al 2016).…”

“…The principal component analysis (PCA) was used as the method for soil indicator selection or the minimum data set (MDS) to reduce the number of indicators or parameters into significant or highly correlated to the principal components avoiding redundancy (Stefanoski et al 2016). It is also widely used to calculate the SQI (Klimkowicz-Pawlas et al 2019). Other methods such as the analytic hierarchy process (Ying et al 2007) are used on a regional scale.…”

The study aimed to determine the soil physicochemical conditions, soil quality index (SQI), its relationship to soil total mercury (THg), and their spatial autocorrelation of the two mercury- contaminated agricultural areas in Monkayo, Davao de Oro, Philippines. Soil physicochemical parameters and THg were assessed, and the data underwent principal component analysis (PCA). The minimum data set (MDS) revealed that percent sand, pH, THg, phosphorus (P), and organic carbon (OC) significantly contributed to the SQI expression. The two agricultural areas (Diwata and Naboc) had comparable (P > 0.05) soil quality indices (0.46 ± 0.073 and 0.46 ± 0.11), which were categorized as Grade 3 (moderate SQI). THg was negatively associated with the SQI, with the regression coefficient (R) equal to –0.419 (p = 0.021); however, this association did not mean a causal effect. Hence, mercury (Hg) contamination could not be singled out as the sole factor in soil quality deterioration but rather the synergistic effects of the agricultural practices and the Hg contamination. Spatial autocorrelation analysis revealed that THg spatial distribution in both areas and the SQI of Diwata were clustered; however, the spatial distribution of SQI in Naboc was random. An in-depth study of soil microbiological function and the ecotoxicological effect of mercury on soil quality is deemed important to be studied.

“…Considering the variety of chemical, physical, and biological properties of soils, there were attempts to categorize some soil properties as indicators of soil health (Magdoff, 2001;Brevik, 2009;Cardoso et al, 2013;Haney et al, 2018;Pawlas et al, 2019), which are mentioned in Table 3. Along with soil health indicators, Magdoff (2001) listed the characteristics of healthy soil (Table 4).…”

Soil is an important natural resource providing water, nutrient, and mechanical support for plant growth. In agroecosystem, continuous manipulation of soil is going on due to addition of input, removal of nutrients, changing water balance, and microbial life. These processes affect soil properties (physical, chemical, and biological), and the deviation of these properties from the normal status is controlled by soil buffering capacity and soil resilience. If these changes are beyond the reach of soil resilience, then soil loses its original state, leading to soil degradation. At present, the extent of the degraded area in the world is 1,036 to 1,470 million ha. This urges the need for maintaining soil health rather than the mere addition of input for crop production. Soil health is an integrative property that reflects the capacity of soil to respond to agricultural intervention, so that it continues to support both agricultural production and the provision of other ecosystem services. Maintaining the physical, chemical, and biological properties of soil is needed to keep it healthy, and this is possible through the adoption of different agronomic approaches. The diversification of nutrient sources with emphasis on organic sources, adoption of principles of conservation agriculture, enhancement of soil microbial diversity, efficient resource recycling through the integrated farming system, and amendment addition for correcting soil reactions are potential options for improving soil health, and are discussed in this review. This article reviewed the concept of soil health and its development, issues related to soil health, and indicators of healthy soil. At the same time, the impact of the ill health of the soil on crop productivity and resource use efficiency reported in different parts of the world in recent years are also reviewed. The agro-techniques such as green and brown manuring in arable land and agroforestry on degraded and marginal land were followed on piece meal basis and for economic gain. The potential of these and several other options for maintaining soil need to be recognized, evaluated, and quantified for their wider application on the front of soil health management avenues. The use of crop residue, agro-industrial waste, and untreated mineral or industrial waste (basic slag, phosphogypsum, etc.) as soil amendments has a huge potential in maintaining healthy soil along with serving as sources of crop nutrition. The review emphasizes the evaluation and quantification of present-day followed agro-techniques for their contribution to soil health improvement across agro-climatic regions and for wider implications. Furthermore, emphasis is given to innovative approaches for soil health management rather than mere application of manures and fertilizers for crop nutrition.
