Structural lineaments in the southern Sierra Nevada, California [PDF]

open access: yes
The author has identified the following significant results. Several lineaments observed in ERTS-1 MSS imagery over the southern Sierra Nevada of California have been studied in the field in an attempt to explain their geologic origins and significance ...

Platinum-group element mineralisation in the Unst ophiolite, Shetland [PDF]

open access: yes, 1984
The ophiolitic basic and ultrabasic rocks of the island of Unst, Shetland comprise a sequence of harzburgites, dunites, clinopyroxene-rich cumulates, and gabbro, within tectonic blocks that have been thrust over a migmatite complex during the Laxer ...

Defining stream riparian zones across multidimensional environmental gradients

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Riparian zones are a critical terrestrial‐aquatic ecotone. They play important roles in ecosystems including (1) harboring biodiversity, (2) influencing light and carbon fluxes to aquatic food webs, (3) maintaining water quality and streamflow, (4) enhancing aquatic habitat, (5) influencing greenhouse gas production, and (6) sequestering ...

Satellite assessment of winter cover crop and conservation tillage outcomes to support adaptive management in working landscapes

open access: yesJournal of Environmental Quality, EarlyView.
Abstract The use of winter cover crops and conservation tillage are agricultural practices promoted to reduce nutrient and sediment loss from cropland, improve soil health, increase infiltration, and support farm nutrient cycling and ecosystem services. However, environmental performance of these practices is variable in the working farm landscape. The

Mechanisms and durations of metamorphic garnet crystallization in the lower nappes of the Caledonian Kalak Nappe Complex, Arctic Norway

open access: yesJournal of Metamorphic Geology
The 3D microstructure and compositional zoning of garnet populations in micaschists from the Kolvik and Bekkarfjord nappes indicate the quasi‐equilibration of their major components across the rock matrices during interface‐controlled, size‐independent ...

Boron availability and fertilizer response of maize in soils from sub‐Saharan Africa

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
Abstract Background and aims Low boron (B) availability is associated with strongly weathered, coarse‐textured, and low organic matter soils, widespread in sub‐Saharan Africa (SSA). It is unknown to what extent B fertilization can increase maize yields in SSA.

Borax Promotes Fertility of Brassica napus Better Than Other Boron Species at Suboptimal Supply

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Continuous and sufficient boron (B) supply is essential for achieving maximum yield in Brassica napus. Increasing incidences of environmental water limitation are linked to reduced plant B availability and increased B deficiencies.

Different Amounts of Added Litter Do Not Affect Long‐Term Carbon Mineralization and Stabilization in Topsoils and Subsoils

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Over half of global soil organic carbon (SOC) stocks are stored in subsoil. A larger fraction of carbon (C) input may be retained and stabilized in subsoil as compared to topsoil. This retained fraction determines C sequestration efficiency, which may also depend on the amount of C input.

Liebig Review: Legume–Rhizobium Symbiosis Under Selenium Fertilization: A Unique Dual Function in the Plant–Soil System

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Selenium (Se) plays a vital role as a beneficial element in promoting the production of leguminous plants. It influences legume quality by improving crop nutritive value and contributing to human and animal health. Literature Review This review is timely, as there are gaps in understanding Se–rhizobia interactions in legumes, which ...
