“…It was reported that solubility of organic matter in the soil inclines with an increase in soil pH, causing the leaching of organic matter and nutrients in alkaline soils (CURTIN et al, 2016). The finding of a significantly low pH level in forest soils in this study is consistent with the previous studies by RODRIGUES et al (2017) andWELDMICHAEL et al (2020). The low pH in forest soils could be attributed to low base cations in the soil or the type of litter residues of forest vegetation (RODRIGUES et al, 2017).…”

Land use change may modify key soil attributes, influencing the capacity of soil to maintain ecological functions. Understanding the effects of land use types (LUTs) on soil properties is, therefore, crucial for the sustainable utilization of soil resources. This study aims to investigate the impact of LUT on primary soil properties. Composite soil samples from eight sampling points per LUT (forest, grassland, and arable land) were taken from the top 25 cm of the soil in October 2019. The following soil physicochemical parameters were investigated according to standard protocols: soil organic matter (SOM), pH, soil moisture, NH4+–N, NO3––N, AL-K2O, AL-P2O5, CaCO3, E4/E6, cation exchange capacity (CEC), base saturation (BS), and exchangeable bases (Ca2+, Mg2+, K+, and Na+). Furthermore, soil microbial respiration (SMR) was determined based on basal respiration method. The results indicated that most of the investigated soil properties showed significant difference across LUTs, among which NO3––N, total N, and K2O were profoundly affected by LUT (p ≤ 0.001). On the other hand, CEC, soil moisture, and Na+ did not greatly change among the LUTs (p ≥ 0.05). Arable soils showed the lowest SOM content and available nitrogen but the highest content of P2O5 and CaCO3. SMR was considerably higher in grassland compared to arable land and forest, respectively. The study found a positive correlation between soil moisture (r = 0.67; p < 0.01), Mg2+ (r = 0.61; p < 0.01), and K2O (r = 0.58; p < 0.05) with SMR. Overall, the study highlighted that agricultural practices in the study area induced SOM and available nitrogen reduction. Grassland soils were more favorable for microbial activity.

“…"Banat 1" had a similar texture to "Banat 2", but the latter had a slightly heavier mechanical composition. The obtained results indicated that the physicochemical properties of "Banat 1" were near the optimal value ranges for earthworms, which was in accordance with the results published by Gebremeskel Weldmichael et al [48] and Weldmichael et al [48]. FTIR characterized all MP particles as polyethylene (PE) (Figure 1).…”

“…The obtained results are supported by the fact that earthworms are hydrophilic, and, therefore, dry sandy soils are not suitable habitats for them. Sandy soils tend to dry out more rapidly and contain limited nutrients and organic matter; therefore, the survival of earthworms in these soil types is very difficult [48]. Additionally, these soil types are not suitable for earthworms due to the sand grains' abrasiveness, which induces cuticle damage [48].…”

The presence of microplastic particles in agroecosystems has profound implications for soil quality, crop yield, and soil biota. Earthworms are widely recognized as valuable soil bioindicators due to their abundance, fast reproduction, and easy manipulation. The aim of this study was to observe Eisenia fetida avoidance behavior and changes in biomass and mortality rate in soil samples spiked with polyethylene microplastic particles. Three types of soil sampled from the agricultural fields (“Banat 1”, “Banat 2”, and “Bačka”) were tested, as well as three microplastic concentrations (0.1, 0.2, and 0.3%). The calculated avoidance percentages ranged from 18.67% for “Banat 1” and 23.70% for “Banat 2” to 27.40% in the case of “Bačka” soil samples. Generally, E. fetida specimens avoided the sections with plastic in all bioassays: 38.42% of the earthworms were in the chamber section that contained microplastics, as opposed to 61.58% in the control section. The changes in the earthworms’ post-test biomasses were directly proportional to the number of surviving earthworms, with the highest loss in “Bačka” soil samples with 0.3% MPs (−53.05%). The highest mortality rate (46%) was noted in “Bačka” soil samples spiked with the highest concentration of microplastic particles.

“…In this study, available-N was not one of the selected indicators for calculating soil fertility index using the conventional method because available-N was not significantly correlated with another chemical indicator. While the indicators used to assess soil fertility index using the modified method are all indicators used in conventional methods, plus indicators of earthworm population density and microbial biomass C. The available-N indicator is included in the modified method because it is significantly positively correlated with earthworm population density; this research result contrasts with [30], which showed no correlation between earthworms and soil chemical properties.…”

Soil fertility is the integrative effect of chemical, physical, and biological soil properties. A modified soil fertility assessment method that adds biological indicators is essential since this indicator is sensitive to dynamic environmental changes and can better represent the reality of soil fertility compared to the conventional method, which only considers chemical soil properties. The research aims to compare the modified and conventional methods in assessing the soil fertility index at various land uses, namely gardens, paddy fields, and moorland, in the Girimarto district, Wonogiri, Indonesia. The collection of soil samples used purposive sampling with three repetitions on 12 land mapping units (LMUs) obtained from an overlay of land use maps, soil type maps, slope gradient maps, and rainfall maps. Soil fertility index (SFI) assessment is based on the Minimum Soil Fertility Indicators (MSFI), which are selected from Pearson correlation, PCA, weight, and score and followed by stepwise regression analysis. The research showed that the modified method represents the soil fertility level better than the conventional one. The soil fertility index on three land uses using the modified method is lower than the conventional method, i.e., between 0.33 to 0.40 and 0.55 to 0.72, respectively. The modified method is more sensitive to dynamic environmental changes due to the contribution of soil biological indicators to the SFI value. Therefore, the biological indicators can represent soil fertility levels closer to reality. Future research needs to validate the modified method in different soil types, land uses, and areas.
