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.

Release of Andean abiotic‐resilient common bean germplasm

Journal of Plant Registrations, Volume 20, Issue 2, May/August 2026.
Abstract Andean abiotic‐resilient (AAR) common bean (Phaseolus vulgaris L.) germplasm lines AAR1 to AAR7 were developed through an international bulk breeding effort to improve abiotic stress tolerance and combine it with disease resistance by increasing genetic richness.

Five decades of hand‐feel soil texture estimation: Accuracy, challenges, and improvements

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Soil texture refers to the proportion of fine soil particles with diameters less than 2 mm, classified into particle size categories that define the soil texture class. Hand‐feel estimation in the field is widely used by soil scientists and technicians during pedological surveys to characterize soil horizons.

Extraction Kinetics and Molecular Size Fractionation of Humic Substances From Two Brazilian Soils

Journal of the Brazilian Chemical Society, 1999
In the present study, the extraction behaviour of humic substances (HS) from an Oxisol and a Mollisol from South Brazil, by using 0.1 and 0.5 mol L-1 NaOH and 0.15 mol L-1 neutral pyrophosphate solutions, respectively, was systematically studied.

Network‐wide assessment of soil water content calibration and sensitivity to biomass proxies using cosmic‐ray neutron sensing in the Roaring Fork Basin, Colorado

Vadose Zone Journal, Volume 25, Issue 3, May/June 2026.
Abstract Soil water content (SWC) is a key state variable of the climate system but is often uncertain in water balance monitoring, especially in alpine environments. SWC measurements can be challenging in alpine environments due to the topography and rocky soils.

Soil health assessment on Native American agricultural land in the semiarid southwest

Vadose Zone Journal, Volume 25, Issue 3, May/June 2026.
Abstract Soil health assessment tools such as the Soil Management Assessment Framework (SMAF) improve the interpretation of soil health status and functional capacity to guide land management decisions. While SMAF has been used in diverse global environments, it has yet to be applied to Native American lands in hot semiarid regions. This study utilizes

Soil Carbon Sequestration Following Natural Vegetation Recovery on Abandoned European Lands: Review and Research Needs

European Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
Environmental factors controlling soil organic carbon sequestration in abandoned European lands, and priority sites for future research across Europe. ABSTRACT Natural vegetation recovery of abandoned agricultural lands could play a significant role in combating climate change by enhancing carbon (C) sequestration over time in a passive and cost ...

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 ...

Distinguishing Soil Horizons of Alfisols Using MIR, Vis–NIR, and XRF Spectra

European Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
ABSTRACT We studied horizonation of 150 Alfisols on a research farm in Wisconsin, USA. Most of these Alfisols had developed in loess covering dense glacial till; common horizons were an Ap over a glossic horizon (E/Bt or Bt/E) over a Bt covering the glacial till (2Bt). In addition to field identification, we distinguished the horizons by combining soil
