Sustainability and integrated weed management in Australian winter cropping systems: a bioeconomic analysis
نویسنده
چکیده
Economic evaluations of the benefits of integrated weed management often only consider the benefits of management in the crop phase, and ignore the impact of rotational options. In particular, non-crop phases such as annual and perennial pasture phases can have a substantial impact upon weed population dynamics and economic returns. Moreover, extended perennial pasture phases are being promoted to address a range of onfarm sustainability issues such as excessive deep drainage (i.e. salinity), runoff and soil erosion. A stochastic bioeconomic model is developed to evaluate potential trade-offs and synergies between the goals of long-term weed management and achieving sustainability goals.

Cropping systems alter weed seed banks in Pacific Northwest semi-arid wheat region
Arable land weed seed banks are dynamic and reflect cropping history, current management, and environment. Changes in crop rotation and tillage system can alter weed seed density and species composition. In the semi-arid region of the Pacific Northwest, USA, no-till spring cropping is being studied as an alternative to the traditional winter wheat (Triticum aestivum L.)/dust-mulch fallow (WWF) ...
متن کاملWeed-species dynamics and management in no-till and reduced-till fallow cropping systems for the semi-arid agricultural region of the Pacific Northwest, USA
Weed management is an important consideration in implementing new cropping systems. In the semi-arid region of the Pacific Northwest, grower interest is increasing in no-till spring cropping systems because of wind erosion from traditional winter wheat Triticum aestivum L./dust-mulch fallow (WWF). However, no-till represents a major shift in production practices and is likely to produce new wee...
متن کاملMeasure and comparison of economic, social and ecological sustainability of farming systems in the Marvdasht plain
Agricultural sustainability refers to the ability of a cropping system to produce, without causing irreversible damage tothe ecosystem. There is an increasing need to view cropping systems and identify management practices in a holisticindicator-based impact assessment. The main objective of this study was to compare and rank the cropping systems of theMarvdasht plain in Fars Province; in order...
متن کاملPotential Alternative Crops for Eastern Oregon
The winter wheat/summer fallow rotation is the most common cropping system in eastern Oregon. It is used to store winter precipitation and control weeds. This cropping system, however, destroys soil organic carbon, reduces water infiltration and thus leads to soil erosion, and is not sustainable. Conservation tillage, annual cropping, and the introduction of alternative crops are ways to improv...
متن کاملA bioeconomic model for analysis of integrated weed management strategies for annual barnyardgrass (Echinochloa crus-galli complex) in Philippine rice farming systems
This paper describes a dynamic simulation model that allows for comprehensive assessment of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli complex) in Philippine rice farming systems. The main outputs of the model include weed seed and plant densities and seasonal and annualised profit over the simulated planning horizon. Results broadly in...
