Peat is one of the most commonly used substrates in soilless cultivation. However, peat mining produces a negative carbon footprint, which raises need for alternative sustainable substrate media. To address this, we studied impact replacement with combination various biochars and cotton burr compost on growth yield cucumber ( Cucumis sativus L.), nutrient concentration media, plant leaf, fruit ...

Indonesian peatlands are one of the largest near-surface pools of terrestrial organic carbon. Persistent logging, drainage and recurrent fires lead to huge emission of carbon each year. Since tropical peatlands are highly inaccessible, few measurements on peat depth and forest biomass are available. We assessed the applicability of quality filtered ICESat/GLAS (a spaceborne LiDAR system) data t...

One important assumption in applying 210Pb-dating is that atmospherically deposited 210Pb is immobilized in the peat or sediment column. This assumption has been challenged widely, but has never been evaluated experimentally. We evaluated Pb mobility and the chemical forms in which Pb is stabilized in peat profiles by adding either soluble or particulate Pb to intact peat cores that were mainta...

A comparison of the kinetics of the sorption of copper(II) on to peat from aqueous solution at various initial copper(II) concentrations and peat doses was made. The Elovich model and the pseudo-second order model both provided a high degree of correlation with the experimental data for most of the sorption process. There was a small discrepancy at the initial stages of sorption which suggested...

(210)Pb and (137)Cs dating techniques are used to characterise recent peat accumulation rates of two minerotrophic peatlands located in the La Grande Rivière hydrological watershed, in the James Bay region (Canada). Several cores were collected during the summer 2005 in different parts of the two selected peatlands. These minerotrophic patterned peatlands are presently affected by erosion proce...

The Canadian horticultural peat industry generates carbon emissions through various methods of peat extraction, processing, and land-use changes. This study provides a carbon emissions analysis comparing the traditional vacuum harvest (VH) and block-cut (BC) extraction techniques to a new acrotelm transplant (AT) method that restores natural peatland function by preserving and replacing the sur...

The performance of autumn and spring-planted strawberry cv. ‘Elsanta’ in peat supplemented with fresh spent mushroom substrate (SMS) Agaricus bisporus, Lentinus edodes, Pleurotus ostreatus 15% 25% was evaluated. morphological yield parameters, dry matter distribution, uptake, partitioning macro- micronutrients were studied. experiment carried out during 2020–2021 an unheated tunnel laid a rando...

Southeast Asia's extensive tropical peatlands account for a significant proportion of the global riverine dissolved organic carbon (DOC) flux to ocean. Peat-derived DOC is rich in polyphenolic compounds, microbial degradation which thought rely on extracellular phenol oxidases. Despite substantial interest biogeochemical fate terrigenous (tDOC), few studies have quantified oxidase activity aqua...
