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.

Phosphorus Plant Availability of Biochars Derived From Contrasting Sewage Sludges to Ryegrass

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Although phosphorus (P) is an essential element for human life, it is currently sourced unsustainably primarily from non‐renewable phosphate rock sources. Sewage sludge pyrolysis is a method that concentrates nutrients in sludge, a large renewable P source, to produce a sustainable phosphorus fertilizer.
