Quantifying the Spatial Footprint of Agriculture‐Driven Edge Effects in a Global Deforestation Hotspot

Global Change Biology, Volume 32, Issue 2, February 2026.
Tropical dry forests face increasing pressure from agricultural expansion, but how this expansion impacts on remaining forests is unclear. We quantified and mapped agricultural edge effects on tree cover, shrub cover, and above‐ground biomass in the Argentine Chaco, a global deforestation hotspot.

The Microbial Functional Communities of Mollisol and Saline–Sodic Paddy Soils at Rice Heading and Harvest Stages in Northeast China

Agriculture
Rice is a primary food source for nearly half of the global population. In Northeast China, paddy soils are mainly classified into two distinct types: fertile mollisol and nutrient-deficient saline–sodic soil.

Rhizosphere Soil Bacterial Communities of Continuous Cropping-Tolerant and Sensitive Soybean Genotypes Respond Differently to Long-Term Continuous Cropping in Mollisols

Frontiers in Microbiology, 2021
The continuous planting of soybeans leads to soil acidification, aggravation of soil-borne diseases, reduction in soil enzyme activity, and accumulation of toxins in the soil.

Relationships Between Soil Phosphorus Fractions and Greenhouse Gas Emissions in Degraded Red and Black Soils Amended With Magnesium Treated Biochar

GCB Bioenergy, Volume 18, Issue 2, February 2026.
The use of pristine and Mg‐modified biochar under acidic soils is of great interest. The biochar addition increases the pH of acidic soils and improves the soil health, and side by side increases the availability of nutrients such as phosphorus. Furthermore, the current study also documented that with the addition of biochar, greenhouse gas emission ...

Assessing impact of conservation agriculture practices on soil physical properties under on‐farm conditions in Central Ohio, USA

Soil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.
Abstract Basic indicators of soil health that influence water infiltration, root growth, gaseous exchange, and overall agronomic productivity are soil physical properties such as bulk density (BD), total porosity (TP), particle density (PD), and penetration resistance (PR).

Dual versus single inhibitors: Which strategy best mitigates nitrogen losses in coarse‐textured soils? A laboratory evaluation

Soil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.
Abstract Enhanced efficiency fertilizers, including urease inhibitors (UIs), nitrification inhibitors (NIs), and dual inhibitors (DIs [UI + NI]), are widely used to reduce nitrogen (N) losses and improve crop nitrogen use efficiency (NUE). However, their relative effectiveness across multiple nitrogen loss pathways remains unclear.

Influence of Extractant and Soil Type on Molecular Characteristics of Humic Substances From Two Brazilian Soils

Journal of the Brazilian Chemical Society, 1999
In a previous study it was observed that humic substances (HS) extracted with NaOH solution and with Na4P2O7 solution presented different molecular weights, and also that the extracted HS yield by each method varied between an Oxisol and a Mollisol from ...
