Comparative field‐scale assessment of TLUD and Kon‐Tiki biochar systems: agronomic performance and net CO2e‐based techno‐economics

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Post‐harvest agricultural residues in Latin America are commonly underutilized, leading to greenhouse gas emissions and lost opportunities for bio‐based value creation. This study tests the hypothesis that decentralized, farmer‐scale pyrolysis technologies can deliver comparable agronomic benefits while exhibiting distinct techno‐economic and ...

Ecology and evolution of pyrazines in insects

open access: yesBiological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Segetal Diversity in Selected Legume Crops Depending on Soil Tillage

open access: yesAgriculture, 2020
The aim of the paper was to determine weed infestation expressed by weeds number and weed weight and other index under a three different tillage system: no-tillage (NT), reduced tillage (RT), and ploughing tillage (CT) in two legume species crops: pea ...

Pre‐industrial land‐use limits contemporary shrub encroachment in the French Alps

open access: yesEcography, EarlyView.
Shrub encroachment has become a global phenomenon in recent decades. While global warming in the Arctic is often cited as the primary cause, human‐managed mountain regions have experienced intense historical land‐use that may also play a considerable role.
