A MAS model for optimizing the spatial aspects of livestock production and manure abatement [PDF]
, 2009 As a consequence of the EU Nitrates Directive many countries have developed policies to regulate manure production and manure emission on land. Farmers have three allocation options: spreading manure on own land, transporting manure to other farmers ...

Depth‐Dependence Changes in Soil Stoichiometry in China's Croplands Over the Past Four Decades
Advanced Science, EarlyView.This study reveals depth‐dependent changes in soil C:N:P ratios across Chinese croplands over four decades. Changes in stoichiometry vary markedly between topsoil and subsoil, with initial soil C:N:P ratios playing a key role in determining their trajectories.

Anaerobic Digestion of Dairy Effluent in New Zealand, Time to Revisit the Idea?
Energies, 2023 The anaerobic digestion of New Zealand low-input dairy farms has previously been evaluated for energy production, but farming systems have recently become more intensive with increased feed supplementation and feed replacement; therefore, we are studying

Advanced Science, EarlyView.This work clarifies how feedstocks and their structural features promote methanogenesis, and identifies the key regulatory factors, reducing pollution to the global environment, and also helps to alleviate the energy crisis. This is the first study to systematically link feedstock lignin content, pyrolysis conditions, biochar graphitization, and DIET ...

Angewandte Chemie, EarlyView.DFT calculations of the 8π‐electrocyclization of 1,2‐bis(diazo)alkanes and of other bis‐1,3‐dipoles reveal that this process can establish a so far ignored route to heterocycles such as 1,2,3,4‐tetrazines. Alternative reaction channels via carbenes or nitrenes leading to fragmentation products are discussed.
