Methods of determining the coefficient of water conductivity in soils

open access: yesБюллетень Почвенного института им. В.В. Докучаева, 2013
The paper is aimed to consider the theory and methods of determining the coefficients of water conductivity and filtration. Soil columns and lysimeters were used for this purpose.

A Simple, Semi-Automated, Gravimetric Method to Simulate Drought Stress on Plants

open access: yesAgronomy, 2022
Drought is a major constraint of global crop production. Given that drought-induced crop losses can threaten world food security, it has been and continues to be the focus of a large body of interdisciplinary research.

The effect of renovation of long-term temperate grassland on N2O emissions and N leaching from contrasting soils [PDF]

open access: yes, 2016
pre-printRenovation of long-term grassland is associated with a peak in soil organic N mineralisation which, coupled with diminished plant N uptake can lead to large gaseous and leaching N losses.

Formation of trifluoroacetic acid from common trifluoromethyl pesticides in agricultural soils

open access: yesJournal of Environmental Quality, Volume 55, Issue 2, March/April 2026.
Abstract The short‐chain per‐ and polyfluoroalkyl substances trifluoroacetic acid (TFA) has been recognized as a degradation product of only three pesticides, but many other trifluoromethyl pesticides (C–CF3 pesticides) may potentially produce TFA based on their molecular structure.

A Review of Lysimeter Experiments Carried Out on Municipal Landfill Waste

open access: yesToxics, 2021
The groundwater risk assessment in the vicinity of landfill sites requires, among others, representative monitoring and testing for pollutants leaching from the waste. Lysimeter studies can serve as an example of dynamic leaching tests.

Long-term Lysimeter Experiments - Findings from Brandis Lysimeter Station 1st Communication

open access: yesArchives of Agronomy and Soil Science, 2002
The goal of these studies was to evaluate lysimeter experiments performed over a number of years on the nitrogen cycle of different soil types to estimate the potential hazard of various types of farming usage resulting from N-leaching losses into the groundwater.

Estimation of Regional Evapotranspiration Using Remotely Sensed Land Surface Temperature. Part 1: Measurement of Evapotranspiration at the Environmental Research Center and Determination of Priestley-taylor Parameter [PDF]

open access: yes, 1985
In order to study the distribution of evapotranspiration in the humid region using remote sensing technology, the parameter (alpha) in the Priestley-Taylor model was determined.

On Utilizing Spatial Gradients to Discover Functional Relationships in Hydrology

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract The search for functional relationships is at the heart of any science, but has proven notoriously difficult in hydrology. Here, we define functional relationships as relationships between two or more variables that characterize the functions of hydrological systems.

Assessing Reference Evapotranspiration Estimation Considering Irrigation Scheduling Intervals

open access: yesAgriculture
Accurate estimation of reference evapotranspiration (ETo) is essential for irrigation planning in semi-arid Mediterranean regions. This study evaluated temperature-based and neural network models for estimating daily ETo and its accumulated values over ...

Model‐Based Interpretation of Solute Exports and Carbon Partitioning During Shale Weathering in a Mountainous Hillslope

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract The weathering of sedimentary rocks in high‐elevation catchments influences freshwater quality and the global carbon cycle. While individual biogeochemical mechanisms involved in this process are relatively well understood, quantifying their contributions to solute export and carbon fluxes under natural, transient conditions remains ...
