Enhanced biobutanol production from rice straw with a two‐stage packed‐bed fermenter coupled with in‐line gas stripping

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND This study describes the operation of continuous packed‐bed reactors containing Clostridium beijerinckii DSM 6422 attached to granular activated carbon to improve butanol productivity and sugar consumption from rice straw hydrolysate. RESULTS A single‐stage fermenter, which was evaluated at dilution rates ranging from 0.3 to 1.8 h−1,

Multimodal Agricultural Agent Architecture (MA3): A New Paradigm for Intelligent Agricultural Decision-Making [PDF]

open access: yesarXiv
As a strategic pillar industry for human survival and development, modern agriculture faces dual challenges: optimizing production efficiency and achieving sustainable development. Against the backdrop of intensified climate change leading to frequent extreme weather events, the uncertainty risks in agricultural production systems are increasing ...

A short history of the phosphorus index and Andrew Sharpley's contributions from inception through development and implementation

open access: yesJournal of Environmental Quality, EarlyView.
Abstract In the 1980s, growing recognition of agricultural phosphorus (P) sources to surface water eutrophication led to scrutiny of animal feeding operations. In 1990, the USDA‐Natural Resources Conservation Service (NRCS) invited prominent scientists to find a solution. It was at an initial meeting that Dr. Andrew Sharpley suggested that P assessment

A review of the development and implementation of the critical source area concept: A reflection of Andrew Sharpley's role in improving water quality

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Critical source areas (CSAs) are small areas of a field, farm, or catchment that account for most contaminant loss by having both a high contaminant availability and transport potential. Most work on CSAs has focused on phosphorus (P), largely through the work in the 1990s initiated by Dr.

Atrazine Ecological Monitoring Program: Two decades of generating daily or near‐daily monitoring data in highly vulnerable watersheds

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Surface water monitoring of pesticides ensures adherence to environmental and human health regulatory requirements. This study focuses on an unprecedented monitoring program spanning two decades with daily or near‐daily sampling across 13 states in the US Midwest and Southern United States, targeting watersheds in the upper 20th percentile of ...

Deviation From the Regression of Yield on Nitrogen Fertiliser Rate as a Tool for Detecting Fraud in Organic Banana Production

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background and aims Bananas are demanding in nitrogen (N) input; therefore, there is a temptation for organic farmers for using synthetic N fertilisers, which are not allowed under organic standards. The aim of our study was to develop a tool that identifies high banana yields obtained with suspiciously low organic N input.
