Evaluation of Physicochemical Properties of Sandy-Textured Soils under Smallholder Agricultural Land Use Practices in Sarawak, East Malaysia

Applied and Environmental Soil Science, 2019
A study was conducted in the Sabal area, Sarawak, to evaluate the physicochemical properties of sandy-textured soils under smallholder agricultural land uses. Study sites were established under rubber, oil palm, and pepper land uses, in comparison to the

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

Soil Diversity (Pedodiversity) and Ecosystem Services

Land, 2021
Soil ecosystem services (ES) (e.g., provisioning, regulation/maintenance, and cultural) and ecosystem disservices (ED) are dependent on soil diversity/pedodiversity (variability of soils), which needs to be accounted for in the economic analysis and ...

Soil potassium pools across depths limit crop response in sandy loam soil

Agronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract Quantifying potassium (K) distribution across soil layers is crucial for understanding the often‐weak relationship between crop response to K fertilization and soil test K (STK). We evaluated exchangeable (STKExch), nonexchangeable (STKNonExch), and semi‐total K (KSemiTotal) at depths 0–20 cm, 20–30 cm, 30–40 cm, 40–65 cm, and 65–90 cm, along ...

Influence of drainage status on soil and water chemistry, litter decomposition and soil respiration in central Amazonian forests on sandy soils [PDF]

, 2011
Central Amazonian rainforest landscape supports a mosaic of tall terra firme rainforest and ecotone campinarana, riparian and campina forests, reflecting topography-induced variations in soil, nutrient and drainage conditions.

Belowground biomass characteristics and soil organic C accumulation of bahiagrass‐based forage systems with or without legumes

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Grasslands are important terrestrial ecosystems that provide feed for livestock, support soil conservation and nutrient cycling, and store soil carbon (C). In many grazed grasslands, restricted nitrogen (N) inputs from fertilizers and minimal legume presence may constrain belowground biomass accumulation and soil C storage because of limited N.

Introduction to the landscapes and soils of the Hamilton Basin [PDF]

, 2010
The Hamilton Basin area is characterised by four main landscape units or landforms as depicted in the block diagrams below (McCraw, 1967, 2002; Bruce, 1979; Selby and Lowe, 1992), and these provide a soil-landscape model to predict the soil ...

Ice storm effects on the canopy structure of a northern hardwood forest after 8 years [PDF]

, 2009
Ice storms can cause severe damage to forest canopies, resulting in differential mortality among tree species and size classes and leading to long-lasting changes in the vertical structure and composition of the forest.

A Systematic Approach to Field Testing of Biological Products for Horticulture Is Required to Improve Food Security

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Food security challenges require immediate action to increase food production. Many biological products derived from plant, animal or microbial sources claim they sustainably increase yield, but there are concerns about biosecurity to be investigated before their introduction to the field.
