“…In the present study, charcoal-enriched horizons were distinguished by higher humidity, suggesting that such soils have a higher capacity to accumulate water. The increase in water holding capacity of biochar-enriched horizons was confirmed in previous studies [60,63].…”

Relict charcoal hearths (RCHs) increases soil fertility in forest ecosystems. However, the effects of RCHs on the activity and abundance of soil microorganisms remain unknown. In this paper, we analysed the impact of relict charcoal production on the soil enzymatic activity and composition of soil bacterial and fungal communities in Scots pine forests of the Manowo Forest District in northern Poland. Moreover, we determined the effect of relict charcoal production on the soil properties. Our research was conducted by comparing the physical, chemical, enzymatic and microbiological properties of charcoal-enriched and charcoal-free soils. Significant differences in physical properties were found between these two soil types in terms of their structure and water holding capacity. As expected, horizons enriched with charcoal were characterised by a significantly higher organic carbon content (4.7% on average compared to 2.2% in control horizons), and also by a considerably higher content of available phosphorus (an average of 64.07 mg·kg−1 compared to 36.21 mg·kg−1 in the control). Similarly, RCH horizons displayed a higher pH and higher contents of Ca and Na cations. These results indicated that RCH soils provided more favourable conditions for the soil microbiome, as reflected by the higher enzymatic activity and diversity of the microorganisms. Moreover, bacterial and fungal communities in RCH soils were more diverse and had greater species/genera richness, especially in the case of fungi. Members of the genus Rhodoplanes dominated the bacterial community at both RCH and non-RCH sites, followed by Streptomyces, Burkholderia, Skermanella, Tsukamurella and Candidatus Solibacter. Both culture- and next generation sequencing (NGS)-based analyses showed that soil fungal communities were dominated by Ascomycota, with Penicillium as the most abundant genus. Our results showed that hearth soils may represent a significant C pool in the forest ecosystem. This study supports the strategy of safeguarding such charcoal-enriched soils as precious C reservoirs and ecologically important biodiversity hotspots. Moreover, the application of charcoal may effectively increase the microbial diversity of forest soils, especially during the reforestation or re-cultivation of disturbed habitats.

“…By means of a meta‐analysis, Razzaghi et al (2020) observed that the effect of biochar on the soil water retention curve depends on soil type. Nonetheless, biochar can be a good option to promote higher water‐holding capacity in sandy soils (Carvalho et al, 2020; Muhammad et al, 2018).…”

Despite their potential as a sustainable source of soil nutrients and organic matter, waste organic residues are often discarded rather than utilized in agriculture. This review examines the current state‐of‐the‐art in the application of organic residues in agricultural production systems by analysing trends and results in published research conducted on their use for soil health and crop production purposes. For this, a bibliographic analysis was conducted on 81 papers collected from the Web of Science database. Our research shows a growing trend in the field, particularly in recent years, with articles from India, China and the United States at the forefront. The most commonly evaluated organic residues were compost, animal manure, crop residues, municipal solid waste and biochar. Soil pH, bulk density and especially organic matter/total organic carbon (TOC) were the chemical, physical and biological attributes most frequently evaluated, respectively. This review indicates that the application of organic residues improves soil health, positively affecting crop productivity in crops such as maize, wheat and rice. However, further research is needed to address the potential risk of soil contamination from potentially toxic metals (PTMs) associated with organic residues, as well as to identify best practices to guarantee food safety and environmental preservation.

“…The high value of BD in the patchouli-developed soil can be reduced by adding organic amendments such as compost, green manure, biochar, or manure. Organic matter has a light-specific gravity so that in the soil it can play a role in reducing the value of bulk density [15] [16]. In Figure 2, it can be seen that the highest soil porosity value of 50.77% is found in ab1 soil samples that are imultiple cropping managed in Woyla Induk District and in AB15 soil samples on hilly land in Sungai Mas District, while the lowest porosity (48.46%) is found in AB2 soil samples, which are also found in Woyla Induk District.…”

Good soil physical characteristics are of great importance to the growth of patchouli plants. This study aims to examine soil conditions analyzed by soil physics in patchouli development areas in Aceh Barat Regency because it is one of the patchouli development areas in Aceh Province. The research method used is a descriptive method, namely through field surveys and laboratory analysis. In this study, we focused on two physical characteristics of soil, namely bulk density (BD) and soil porosity. Soil samples were taken purposively at 15 patchouli planting sites in three sub-districts in Aceh Barat, namely of Woyla Barat, Woyla Induk, and Sungai Mas, each representing a monoculture, multiple cropping and mixed garden system. Each site was given five points of soil samples at a depth of 0–30 cm using sample rings. The results of the analysis showed that, in general, the bulk density (BD) of the soil is included in the weight category with BD values ranging from 1.27–1.30 Mg/m3, while the porosity of the soil is classified as rather poor to rather good with values ranging from 48.46–50.77%. From the analysis of the data obtained, it shows that the entire patchouli development area in West Aceh has relatively homogeneous soil physics characteristics from the aspect of soil physics and soil constraints are found in poor conditions. Therefore, to improve soil quality, it is necessary to add ameliorant materials, especially types of organic amendments such as compost, biochar, manure, and other supporting factors.
