TLDR
In this paper, a database of Polish arable mineral soils is presented, which includes a lot of information about the basic properties of soils and their dynamic characteristics, including particle size distribution, organic carbon content, acidity-pH, specific surface area, hydrophobicity, static and dynamic hydrophysical properties, oxidation-reduction properties and selected biological (microbiological) properties.Abstract:
A b s t r a c t. The database of Polish arable mineral soils is presented. The database includes a lot of information about the basic properties of soils and their dynamic characteristics. It was elaborated for about 1 000 representative profiles of soils in Poland The database concerns: particle size distribution, organic carbon content, acidity-pH, specific surface area, hydrophobicity – solidliquid contact angle, static and dynamic hydrophysical properties, oxidation-reduction properties and selected biological (microbiological) properties of soils. Knowledge about soil characteristics is indispensable for description, interpretation and prediction of the course of physical, chemical and biological processes, and modelling these processes requires representative data. The utility of simulation and prediction models describing phenomena which take place in the soil-plant-atmosphere system greatly depends on the precision of data concerning characteristics of soil. On the basis of this database, maps of chosen soil properties are constructed. The aim of maps is to provide specialists in agriculture, ecology, and environment protection with an opportunity to gain knowledge of soil properties and their spatial and seasonal variability.

Bacteroidetes as a sensitive biological indicator of agricultural soil usage revealed by a culture-independent approach
Agnieszka Wolińska,Agnieszka Kuźniar,Urszula Zielenkiewicz,Dariusz Izak,Anna Szafranek-Nakonieczna,Artur Banach,Mieczysław Błaszczyk +6 more
TL;DR: The Bacteroidetes phylum was found to prefer colonising the non-cultivated AG and HG soils rather than the LG soils, which proves its sensitivity to agricultural practices and is recommended as a sensitive biological indicator of agricultural soil usage.

Factors influencing humus forms and forest litter properties in the mid-mountains under temperate climate of southwestern Poland
TL;DR: In this paper, the authors focused on the relationship between altitude, bedrock and soil type (trophic factors) and tree stand composition (a biotic factor steered by humans), and humus form, taking into account the forest litter and (mineral) humus horizon characteristics.

Organic carbon pools in mountain soils — Sources of variability and predicted changes in relation to climate and land use changes
Oskar Bojko,Cezary Kabała +1 more
TL;DR: In this paper, the authors investigated the effect of natural and anthropogenic factors on the amount and diversity of soil organic carbon (SOC) pools in mountain areas and verified whether the humus form is a predictor of the organic carbon pool in mountain soil.

Conversion of soil pH 1:2.5 KCl and 1:2.5 H2O to 1:5 H2O: conclusions for soil management, environmental monitoring, and international soil databases
TL;DR: In this paper, the authors derived that pH values measured at soil:solution ratios 1:2.5 and 1:5 in distilled water and KCl solution, respectively, have nearly identical values and do not require conversion in most practical applications.

Metagenomic Analysis of Some Potential Nitrogen-Fixing Bacteria in Arable Soils at Different Formation Processes
Agnieszka Wolińska,Agnieszka Kuźniar,Urszula Zielenkiewicz,Artur Banach,Dariusz Izak,Zofia Stępniewska,Mieczysław Błaszczyk +6 more
TL;DR: It is found that both soil agricultural management and soil formation processes are the most conducive factors for PNF bacteria, as a majority of these microorganisms inhabit the AG group of soils, whilst the LG soils with the lowest abundance of PNFacteria revealed the need for additional mineral fertilisation.

Developing joint probability distributions of soil water retention characteristics
TL;DR: In this paper, a method is presented for developing probability density functions for parameters of soil moisture relationships of capillary head [h(θ)] and hydraulic conductivity [K(α), which are required for the assessment of water flow and solute transport in unsaturated media.

Development and use of a database of hydraulic properties of European soils
TL;DR: The HYPRES database as discussed by the authors contains information on a total of 5521 soil horizons (including replicates). Of these, 4030 horizons had sufficient data to be used in the derivation of pedotransfer functions.

Methodological aspects of determining soil particle-size distribution using the laser diffraction method.
TL;DR: In this article, the influence of selected methodological aspects on the results of particleize distribution (PSD) as measured by the laser diffraction method (LDM) was presented, and it was found that most of the discussed parameters depend on design of the measuring device and on the type and volume of the investigated suspensions.
