Soil Fertility and Nutrient Management on Spodosol for Oil Palm [PDF]

, 2010
The research was carried out in Oil Palm Plantation in Ngabang, Landak Distric, West Kalimantan in May 2008. Composite soil samples were taken from the soils, in which the oil palms indicated the nutrient disorders. The aims of the research were to study

High‐Resolution Soil Total Phosphorus Mapping for the Conterminous USA Using Machine Learning

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Accurate estimates of soil total phosphorus (TP) concentrations are essential for sustainable nutrient management, food security, and water quality protection. This study predicts and maps the spatial distribution of TP in the top 5 cm and C horizon of soils across the conterminous USA (CONUS) using data from the Geochemical and Mineralogical ...

Biogeochemical asymmetry and the diversification of tropical rain forests in Borneo: The endmember hypothesis

Functional Ecology, Volume 40, Issue 1, Page 4-14, January 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mixed dipterocarp lowland tropical rain forests on Oxisols and Ultisols and heath forests on Spodosols are considered distinct vegetation types in Borneo. Here we present the endmember hypothesis of ecosystem diversification, which describes a continuum of forest ...

Taking the pulse of snowmelt: in situ sensors reveal seasonal, event and diurnal patterns of nitrate and dissolved organic matter variability in an upland forest stream [PDF]

, 2011
Highly resolved time series data are useful to accurately identify the timing, rate, and magnitude of solute transport in streams during hydrologically dynamic periods such as snowmelt. We used in situ optical sensors for nitrate (NO3 −) and chromophoric

Leaf nitrogen and wood density, but not root traits, explain the growth and survival of temperate tree species

Journal of Ecology, Volume 114, Issue 1, January 2026.
The relative importance of different root traits for tree growth and survival may be contingent on the soil environment, so that species' demographic strategies cannot be confidently inferred from below‐ground traits without biotic or abiotic environmental context.

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 ...

The Holocene evolution of Rheban Spit, Tasmania. 2. Soil development trends [PDF]

, 1987
Calcareous sands and podzols of four different ages (0, 3 100, 4200 and 5500 calendar years) form a soil chronosequence at Rheban Spit, a prograded sand barrier, near Orford on the east coast of Tasmania.

Unravelling Subsoil Acidification: Mechanisms, Consequences and Remediation

Soil Use and Management, Volume 42, Issue 1, January‐March 2026.
ABSTRACT Subsoil acidification is an intractable agronomic challenge worldwide, and its amelioration is costly and often practically infeasible. Because most studies are confined to the topsoil, acidity development in subsoil commonly remains undetected until it becomes severe.
