Description

The deposited data were collected as part of the research project entitled ‘Wpływ biowęgla wzbogaconego mikrobiologicznie na właściwości fizykochemiczne i biologiczne agregatów glebowych - badania modelowe’, eng. ‘The influence of microbiologically enriched biochars on the physicochemical and biological properties of soil aggregates - model studies’, financed by the National Science Centre, Poland, as part of the project under the SONATA 17 (project no: 2021/43/D/ST10/01656). The research is based on model aggregates made from biochar and biochar enriched with microorganisms (Trichoderma) with soils of a different texture class and physicochemical properties. Research in the project includes bulk density tests, effects on structure and pore characteristics, water and mechanical aggregate stability, wettability, microorganisms activity, and other physicochemical and biological parameters.

The research was conducted from November 2022 to April 2023 at the Institute of Agrophysics, Polish Academy of Sciences in Lublin. The collection contains data on water vapor and nitrogen adsorption isotherms obtained for various biomasses and biochars produced from those biomasses at different temperatures.

The dataset consists of the following files:

A_1.xlsx – Raw data of water vapour adsorption isotherms obtained for various biomasses (willow sawdust, peat, three organic sludges) and biochars produced from those biomasses at different temperatures (300, 450, 600 °C).

A_2.xlsx – Raw data of nitrogen adsorption isotherms obtained for various biomasses (willow sawdust, peat, three organic sludges) and biochars produced from those biomasses at different temperatures (300, 450, 600 °C).

The data was compiled on the basis of laboratory tests.

The results presented in file A_1 were obtained using the following research equipment: Vacuum dryer (OV-12, Jeio Tech, Republic of Korea), Vacuum dryer DZ-2BC (Chemland, Poland).

The results presented in file A_2 were obtained using the following research equipment: 3Flex surface analyzer (Norcross, GA, USA).
