“…However, this study has shown that urban vegetated areas can be sealed, reducing their potential for providing ecosystem services to cities. Our results presented higher values of density than those observed in other studies [65][66][67][68][69]. Nevertheless, there are few studies of bulk density in urban areas, since forest or rural soils used for agriculture and pasture are more explored [70][71][72][73][74].…”

Permeable surfaces are increasingly rare in urban centers, but they have the utmost importance for stormwater infiltration. In this context, green spaces are key to reducing problems caused by runoff. This work aimed to evaluate the physical characteristics of the soil used for agroecological gardening, in comparison with parks, wasteland, and riparian forest in Sorocaba, São Paulo, Brazil. During the one-year data collection, urban gardens were superior to other areas in hydraulic conductivity (35.8 mm h−1), humidity (25.8%), and soil penetration resistance (1.21 MPa). On the other hand, the riparian forest showed signs of soil degradation, with low water infiltration rates (121.9 mm h−1) and humidity (14.4%). These findings highlight the importance of better soil management solutions to avoid compaction, such as the protection and conservation of riparian forests. Furthermore, the encouragement of urban gardens and parks with multiple uses can be an option for the enhancement of stormwater management in cities, since this practice has the potential to improve the physical characteristics of urban soils and provide several ecosystem services.

“…As such, it is commonly considered as a suitable trait for efficient measurement of soil carbon and nutrient stocks (Bondi et al, 2018). There is only little knowledge about bulk density, since the measurement of this parameter is demanding, as it is pointed out in the work by Premrov et al (2017).…”

In the current study, we investigate the relationships among the soil functional diversity, physicochemical properties and heavy metals presence in an ecological farming system. The soil samples were collected from permanent research sites, from A soil horizons, at a depth from 0.05 m to 0.15 m, in June 2018. In fresh soil samples, we evaluated the metabolic profiles of their microbial communities, using Biolog® Eco Plates. The research showed that the soil physical properties got adjusted after a long-term application of an ecological farming system and that the measured values were stabilised, reaching the levels comparable with the average values for the relevant soil type. It is necessary to devote a continual attention to soil reaction, because soil is naturally acidified through acid atmospheric fallout as well as through calcium uptake-off by plants. The values of the selected heavy metals in the monitored period did not exceed the limit values specified in the Act No. 220/2004 Coll. Based on the results of Shannon’s diversity, we can conclude that the diversity in the investigated sites was low, from moderate to medium. The differences (3.26–3.36) among all 11 study localities were very small and not significant. There were determined the correlations between the soil functional diversity, soil physicochemical properties, and heavy metal contents. The average well colour development (AWCD) positively correlated with soil reaction and with Mg content and significantly negatively correlated with contents of Hg, Zn and Cu; equitability significantly positively correlated with soil reaction, Mg, AWCD and Shannon’s diversity. Spearman’s correlation coefficients confirmed the positive correlation between Shannon’s diversity and soil reaction, AWCD and Mg. In our study, no correlation was found between the functional diversity of microorganisms and the soil physical properties.

“…Bondi et al, (2018) estimated BD for peat soils using soil visual assessment, and decision trees achieving similar performances, with around 0.6 explained variance. Premrov et al, (2018) achieved similar performances (R 2 from 0.4 to 0.6) using optimal power-transformation of measured physical and chemical soil parameters. Chen et al (2018) formalized an analytical protocol to test the PTF prediction at regional scales in France by building a Boosted Regression Tree (BRT) model to obtain reliable predictions (R 2 0.7) , and also applied the advanced deep learning modelling framework for the evaluation of in situ spectral measurement of SOC with in situ vis-NIR spectroscopy in southeastern Tibet (Chen et al, 2020) achieving (R 2 = 0.92).…”
