Benzimidazole Anthelmintic Compounds Albendazole and Fenbendazole Show Distinct Toxicity on the Nitrogen Fixing Bacterium Mesorhizobium loti and Its Symbiosis With Lotus japonicus

Environmental Toxicology, EarlyView.
ABSTRACT Veterinary medicines, which reach the soil mostly through the application of contaminated manures, can affect beneficial soil microorganisms, such as nitrogen‐fixing rhizobia bacteria, which engage in important symbiotic associations with plants.

Weed supression by smother crops and selective herbicides

Scientia Agricola, 2004
Using a smother crop is thought to suppress weed density and to add other beneficial effects in sustainable agricultural systems. Weed suppression ought to be considered an essential component of integrated weed management.

Including Harvested Grain Biogenic CO2 to Address a Critical Flaw in Climate Accounting

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT The international climate accounting system excludes both the biogenic CO2 sequestered in harvested crops and the biogenic CO2 emissions that occur when grain is digested or burned as biofuel. Despite being described in the literature as a critical flaw in climate accounting all parties within the United Nations Framework Convention on Climate

Dynamic Model as Attainment Effort of Nitrogen Synchronization at Lettuce Cultivation with Green Manure Paitan

Journal of Tropical Soils, 2009
Lettuce (Lactuca sativa) is vegetable crop that consumed part of the leaf and harvested at a phase of vegetative. Nitrogen play important role in growth at phase of vegetative. Nitrogen in spacious have the character of easy to lose because of leaching.

The Price Gap in Agriculture‐Based Greenhouse Gas Offset Markets

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Today, there is a global effort to reduce greenhouse gas net emissions (GHGNE). For economic well‐being, it is important to identify low‐cost means of net emission offsets. Agriculture and forestry have received considerable attention as a means of supplying emissions offsets, as they contribute nearly 20% of global emissions.

Policy Evaluation for Climate Mitigations in the European Agricultural Sector—A Comparison of Policy Options at Micro and Macro Level

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT The purpose of this paper is to discuss the micro‐ and macro‐outcomes for the standard neoclassical carbon tax (whose burden falls on the producers) versus the implication of a budget neutral, performance‐based EU Common Agricultural Policy (CAP) focusing on non‐CO2 emission (N2O and CH4, measured in CO2eq) reduction, especially in the ...

Emission Reporting for Agriculture: Frameworks and Metrics Matter

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Frameworks and metrics that reliably describe agricultural emission sources and carbon sinks are critical to the formulation of cost‐effective mitigation investment. This study identifies and compares three distinct emission reporting frameworks across metrics of total emissions and emissions intensity.
