Land Degradation &Development, Volume 37, Issue 15, Page 10732-10745, September 2026.ABSTRACT Long‐term straw returning is widely promoted to improve soil quality in intensive cropping systems, yet its combined effects with mineral fertilization on soil quality and phosphorus (P) loss risks remain unclear. Using a 16‐year field experiment in a rice–wheat rotation system, we evaluated the impacts of straw returning (S), NPK ...

Aluminum extraction with nitrogen-containing phenolic extractants [PDF]
, 2015 Liquid extraction is a promising method of aluminum extraction from potassium bittern (mother liquors) solutions. Extractants are nitrogen containing chelating phenol type compounds, namely: N-(2-hydroxy-5-nonylbenzyl)-β,β-dihydroxyethylamine (NBEA-0 ...

SyntheseAbstract Since Clark and Chalmers advanced “The Extended Mind” in 1998, a persistent dispute evolved on how our tool interactions shape the kind of cognition we have. Extended cognition generally views us as cognitively augmented and enhanced by our tool practices, which shall render our cognitive constitution extended to those tools. Bounded

Novel extractants for the recovery of fermentation derived lactic acid [PDF]
, 2013 Reactive liquid–liquid extraction is a promising technology for the removal of lactic acid directly from fermentation media. For over five decades, tertiary amines (e.g.

ASSESSMENT of MICRONUTRIENT EXTRACTANTS FROM SOILS of PARANA, BRAZIL
, 2014 In Brazil, plant-available micronutrients in the soil can be determined by several chemical extractants, the most common of which are dilute acid and chelating solutions. The purpose of this study was to assess the extractants 0.1 mol L-1 HCl, Mehlich-1,

Extraction of scandium ions by new aminophosphinyl extractants
, 2020 Extraction of Sc(III) ions by new aminophosphinyl compounds containing one or two methylenediorganylphosphinyl groups at the nitrogen atom was studied with a target of the development of effective and selective extractants of trace elements.
