“…The hydroponic production implementation can help to diversify agricultural practices in the locality, considering that there is a concentration of food production related to the binomial soy (49% of the agricultural area produced in 2019) and corn (40% of the agricultural area produced in 2019) in the municipality (IBGE 2021 ). In this way, hydroponic production in Dourados could contribute to land use by optimizing natural resource use through more sustainable production practices, keeping in mind that one of the advantages of hydroponics is the reduction of adverse environmental effects and the contribution to food security (McKeon-Bennett, HodKinson 2021 ). Hence, land use can be more effective, with the possibility of expanding these agricultural practices in urban areas if hydroponics practices are incorporated into local food cultivation.…”

Objective is to analyze the economic feasibility of implementing a greenhouse in a hydroponics production system in substrate (sand) on a small family farm as an alternative to hydroponic cultivation using nutrient film technique (NFT). This case study was carried out in the Municipality of Dourados, Mato Grosso do Sul state, Brazil. The location was specifically selected because of the importance of agricultural activities and the need for productive diversification related to the context of the small rural producer. As a criterion for assessing economic viability, the techniques of net present value (NPV), internal rate of return (IRR), modified internal rate of return (MIRR), cost–benefit (C/B), profitability index (PI), equivalent annual value (EAV) and discounted payback (DP) were under consideration. A minimum attractiveness rate adjusted to the risk of emerging countries of 10.25% per year was considered. The viability of the project was verified, even when exposed to risk and uncertainty.

“…In addition, the vegetation type of peat has an undeniable influence on the bacterial and fungal communities in peat. In a recent review, the unique characteristics of Sphagnum mosses, which promote the growth of endophytic bacteria and fungi, were demonstrated [18]. The importance of understanding the peat microbiome turned out to be a key emphasis of that study.…”

“…Other groups of microorganisms in the peat ecosystem were not targeted in the research in a wider context. Some microbiology-based studies on peat have been carried out in the United States, Canada, Thailand and Australia [17][18][19][20]. It is still at a rudimentary level in Ireland.…”

Soil microbial ecology in the Irish wetlands is still poorly understood, although it is crucial in introducing effective rewetting schemes to restore and conserve the Irish peatlands. As an initiative, peatlands with distinct land-use types (cutaway, raised semi-degraded, unimproved grassland and grassland) were collected from farms in the midlands to analyse various microbial populations. Peat was homogenized and serially diluted to culture on a range of specific and non-specific culture media. Culture isolation and microbial enumeration were performed. Gram staining and other microscopic observations of morphologically distinct microorganisms were performed, followed by isolation procedures. The numbers of total viable bacteria of cutaway bog and unimproved grassland were 4.23 × 103 CFU g−1 and 9.81 × 107 CFU g−1, respectively, with a significant statistical difference (p ≤ 0.05). Raised semi-degraded bogs comprised low values of both aerobes and fungal populations. Penicillium spp. and Trichoderma spp. were common in many vegetation types. Phosphate-solubilizing bacteria were present in the majority of the study sites. This indicated that the soluble form of phosphorus was being assimilated by plants. Cutaway peat contained the bacteria with the highest phosphate-solubilizing index (3.167). Overall, the number of culturable microbial groups in cutaway and raised semi-degraded peatlands exhibited significant differences, while the rest did not show drastic changes according to land-use type. This study provides baseline data to continue studies on bog microbiology, which provides a new outlook for restoration. Future work should consider microbial interaction with environmental variables in different land-use types.

“…Carboxyl and phenolic functional groups present in humic substances, which make up peat organic matter, influence peat chemical properties such as metal complexation, buffering capacity, acid–base reactions, and cation exchange capacity 20 , 21 . Also, Sphagnum moss, due to the high cation exchange capacity of its surface, is suitable for monitoring atmospheric element depositions 11 , 22 – 25 . However, only some elements were investigated, while others could be bound by Sphagnum moss, as pointed out by other authors 24 .…”

“…They also play a key role in the conservation of biodiversity by ensuring habitat for various living species, paleoenvironmental archives, and archaeological remains and play a special role in hydrological cycle regulation through water storage, groundwater recharge, and drought and flood mitigation 7,8 . In addition, peat and Sphagnum moss are recognized globally as valuable economic resources for their use as fuel and horticultural substrate, respectively [9][10][11] . However, peat is a non-renewable resource 6 .…”

Peatlands in southern South America (Tierra del Fuego region, TdF) play a key role in the ecological dynamics of Patagonia. It is, therefore, necessary to increase our knowledge and awareness of their scientific and ecological value to ensure their conservation. This study aimed to assess the differences in the distribution and accumulation of elements in peat deposits and Sphagnum moss from the TdF. Chemical and morphological characterization of the samples was carried out using various analytical techniques, and total levels of 53 elements were determined. Furthermore, a chemometric differentiation based on the elemental content of peat and moss samples was performed. Some elements (Cs, Hf, K, Li, Mn, Na, Pb, Rb, Si, Sn, Ti and Zn) showed significantly higher contents in moss samples than in peat samples. In contrast, only Mo, S and Zr were significantly higher in peat samples than in moss samples. The results obtained highlight the ability of moss to accumulate elements and to act as a means to facilitate the entry of elements into peat samples. The valuable data obtained in this multi-methodological baseline survey can be used for more effective conservation of biodiversity and preservation of the ecosystem services of the TdF.
