Potential pitfalls when using popular chemical extractions to characterize Al‐ and Fe‐containing soil constituents

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
Abstract Wet‐chemical extraction of soil to quantify pedogenic species or to remove specific compounds prior to other analyses is an established approach in analytical soil mineralogy and soil chemistry. Interpretation and informational value of data derived from long‐established and frequently used extractions, for instance involving dithionite ...

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.

Late Pebble Accretion of Comet 81P/Wild 2 Nucleus: Evidence from a Plagioclase-bearing Chondrule Fragment, Pyxie

open access: yesThe Astrophysical Journal
Comet 81P/Wild 2 is a ∼4.5 km-sized primordial object that almost has not been modified by internal heating by ^26 Al decay. Its nucleus could have been formed by hierarchical agglomeration or gravitational collapse of pebble swarms concentrated by ...

Natural Colloids in Soil: Effect of Storage and Extraction Conditions on Colloid Amount and Composition

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Natural soil colloids (1–1000 nm) play a crucial role in the mobility and cycling of nutrients. In many studies, colloids are analyzed mainly as so‐called water‐dispersible colloids (WDCs), with varying storage and extraction steps.
