Elevated cadmium (Cd) concentrations in cacao and cocoa-based products (e.g., chocolate) present a potentially serious human health risk. While recent regulatory changes have established a threshold of 0.8 mg kg-1 for Cd content of cocoa-based produc

Abstract Aminopeptidases are one of the extracellular hydrolytic enzymes that catalyze organic nitrogen (N) depolymerization and are commonly assayed using fluorogenic substrates. However, chromogenic substrates based on para‐nitroaniline (pNA) dev

Abstract Long-term agricultural experiments are essential to measure the impacts of farming practices on crop yields, soil fertility and biogeochemical processes. However, these impacts often only manifest at decadal timescales, requiring committed a

Struvite (NH4MgPO4·6H2O) is a slow-release phosphorus (P) fertilizer hypothesized to reduce nutrient leaching losses relative to highly water-soluble counterparts such as monoammonium phosphate (MAP). We assessed the leaching fate of P from struvite

Environmental evaluations of metal nanoparticles (NP) rely on seperating the effects of the metal NP from its dissolution products. However, the coordinating or counter anion used in experimental controls may potentially influence biotic indicators u

Abstract In the last two decades, permanganate has been used to define what is assumed to be a labile or “active” soil carbon (C) pool, commonly referred to as “permanganate‐oxidizable carbon” (POXC). However, uncertainties in the reduction

Abstract Diverse patterns of climate and edaphic factors challenge detection of soil property change in the US Great Plains. Because detectable soil change can take decades, insights into the trajectory of soil properties frequently require long‐te

Abstract Ammonium phosphate fertilizers are a common phosphorus (P) source for crops, namely monoammonium phosphate, diammonium phosphate, and ammonium polyphosphate. Despite containing appreciable nitrogen (N), ammonium phosphate fertilizers are gen

Aminopeptidases catalyze the hydrolysis of peptides into constituent amino acids and are therefore a key step in nitrogen (N) depolymerization and downstream mineralization. Differences in carbon (C):N as well as sulfur (S) content of amino acids pre

Earthworms can increase the solubility of phosphorus (P) in soil, an effect which to a large extent is controlled by mineralisation of organic P. Phosphatases, a class of hydrolytic enzymes, catalyse this mineralisation process. However, a consistent
