Spatial Distribution of Parthenium hysterophorus: Impact on Plant Species Diversity and Soil Characteristics in Gamo Zone, Southern Ethiopia

Plant-Environment Interactions, Volume 7, Issue 2, April 2026.
ABSTRACT The invasions are severe and have an impact on pasture lands, farmlands, and conservation areas. However, there is little data on Parthenium hysterophorus L. (Parthenium) mapping using GIS in the Southern Region of Ethiopia. The objective of this study was to map the spatial distribution of Parthenium which affects the diversity of plant ...

Soil Carbon in Agroforestry Systems: An Unexplored Treasure? [PDF]

, 2009
Soil organic matter (SOM), which contains more reactive organic carbon (C) than any other single terrestrial pool, plays a major role in determining C storage in ecosystems and regulating atmospheric concentrations of carbon dioxide (CO2)^1 ...

Impact of Fire and Heat Stress on Soil Microorganisms: A Review of Community Changes, Molecular Responses and Plant‐Beneficial Roles

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This work reviewed the direct and indirect effects of fires on microbial communities and the resilience strategies microbes use to withstand high temperatures . ABSTRACT Fire, whether occurring on the surface or underground, significantly influences soil microbial dynamics by reshaping community composition, functional diversity and overall soil and ...

Assessing Spatial and Temporal Variability for Some Edaphic Characteristics of Mediterranean Rainfed and Irrigated Soils

Agronomy, 2019
Mediterranean soils are particularly threatened by salinization and low levels of organic matter content. In order to assess an edaphic sustainable use, we need to study its characteristics and better understand the temporal and spatial evolution.

Potassium fertilization enhances teff [Eragrostis tef (Zuccagni) Trotter] productivity across contrasting soils in Omo‐Nada, southwestern Ethiopia

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Potassium (K) is an essential macronutrient vital for plant growth and crop production. However, the misconception that K fertilization is unnecessary has long persisted in Ethiopia. Hence, a field experiment was conducted during the 2021 and 2022 cropping seasons on Nitisol and Cambisol soils to evaluate the response of teff [Eragrostis tef ...

Stability of soil aggregates and their ability of carbon sequestration

Soil and Water Research, 2014
One of the most important binding agents for forming stable aggregates is a soil organic matter (SOM), which can be retained in various size fractions of aggregates. If aggregates are water-resistant, they retain more carbon.

Methylocella silvestris sp. nov., a novel methanotroph isolated from an acidic forest cambisol [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2003
Two strains of Gram-negative, aerobic, non-pigmented, non-motile, rod-shaped, methane-oxidizing bacteria were isolated from an acidic forest cambisol near Marburg, Germany, and were designated as strains BL2(T) and A1. These bacteria were morphologically and phenotypically similar to Methylocella palustris K(T).
