AN ECONOMIC AND RISK ANALYSIS OF THE EFFECTS OF TILLAGE AND NITROGEN SOURCE ON SOIL CARBON SEQUESTRATION IN CORN PRODUCTION [PDF]

open access: yes
The economic potential of no-tillage versus conventional tillage to sequester soil carbon using either commercial nitrogen or manure for continuous corn production is evaluated. Results indicate which system provides the highest net returns, which system

Earthworm populations in conventional/organic arable-based systems and their contribution to soil fertility OF0117T [PDF]

open access: yes, 1995
The project aimed to characterise earthworm population dynamics and behaviour under rotational cropping, comparing organic and conventional systems. Benefits arising from earthworm activity in terms of soil fertility were also assessed.

Electrochemical Nitrate Reduction Reaction to Ammonia at Industrial‐Level Current Densities

open access: yesAdvanced Science, EarlyView.
This review starts from the mechanism and theoretical basis of electrochemical nitrate reduction reaction (NO3−RR), and systematically summarizes and discusses the design strategies of industrial‐level current density catalysts. In addition, the progress of industrial‐level NO3−RR‐based electrolyzers, including flow reactor and membrane electrode ...

Do Consumers Value Diversity in Agriculture? A Choice Experiment

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Farm ownership in the US today is racially and ethnically homogeneous. Diverse farmers and ranchers make up less than 10% of all producers, they tend to be less financially stable and have tighter profit margins. In the past few years, both government and industry programs have aimed to increase the participation and profitability of diverse ...

Influence of notillage on carbon sequestration and erosion in Brazil [PDF]

open access: yes, 2004
Les sols constituent le plus gros réservoir superficiel de C (hors les roches carbonatées), environ 1500 Gt C, ce qui équivaut à presque trois fois la quantité stockée dans la biomasse terrestre, et deux fois celle de l'atmosphère.

Designing Cost‐Effective Carbon Payments to Induce Cellulosic Feedstock Production for Sustainable Aviation Fuel

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Perennial bioenergy crops, such as miscanthus and switchgrass, and crop residues have the potential to scale up sustainable aviation fuel (SAF) production and mitigate carbon emissions. However, high establishment costs, delayed returns, and risk–return profiles that diverge from those of conventional crops can hinder incentives to adopt ...

Modeling soil organic carbon change in croplands of China [PDF]

open access: yes, 2003
Using 1990 conditions, we modeled carbon (C) and nitrogen (N) biogeochemical cycles in croplands of China (and, for comparison, the United States) to estimate the annual soil organic-carbon (SOC) balance for all cropland.
