Wet‐dry cycles control the emissions and sources of greenhouse gases in agricultural soil: An incubation study

Journal of Environmental Quality, Volume 54, Issue 6, Page 1773-1787, November/December 2025.
Abstract This study examines the impact of wet‐drying cycles and nitrogen (N) fertilization on soil greenhouse gas fluxes, specifically nitrous oxide (N2O) and carbon dioxide (CO2). Nine treatments were tested, combining three soil moisture regimes (55% constant, 55%–30% cycle, and 80%–55% cycle) with three N addition rates (0, 100, and 150 kg N ha−1 ...

Multiyear changes in snowmelt phosphorus runoff with soil P drawdown or application of struvite to an organic forage crop

Journal of Environmental Quality, Volume 54, Issue 6, Page 1985-1995, November/December 2025.
Abstract In this study, changes in P runoff losses from three field‐scale small watersheds in the Northern Great Plains region (Manitoba, Canada) under organic management were evaluated over a 7‐year period (2017–2023). A perennial forage crop was grown through this time period, either with biennial addition of a slow‐release fertilizer to maintain ...

Adjusting Bulk Density Observations in the Hungarian Soil Information and Monitoring System Using Pedotransfer Functions

European Journal of Soil Science, Volume 76, Issue 6, November–December 2025.
ABSTRACT Bulk density (BD) is among the most important physical soil properties, influencing many other soil properties, functions and services. An earlier study revealed that BD observations in the Hungarian Soil Information and Monitoring System (SIMS) contain errors and need correction.

ON OSIP MANDELSTAM’S POEM «CHERNOZEM»

Russkaya literatura, 2021
The article offers the analysis of «Chernozem» («Humus»), a complex late-period poem by Osip Mandelstam. The author relies on the poet’s own opinion about «Chernozem», cited in the letter of S. B. Rudakov to his wife, and suggests that the poem should be read as a manifesto of the «New Ac-meism», in which the stone is replaced by the Voronezh humus.
