Canola-Wheat Rotation versus Continuous Wheat for the Southern Plains

Duke, Jason C.; Epplin, Francis M.; Vitale, Jeffrey D.; … - Southern Agricultural Economics Association - SAEA - 2009

Crop rotations are not common in the wheat belt of the Southern Plains. After years of continuous wheat, weeds have become increasingly difficult and expensive to manage. Yield data were elicited from farmers and used to determine if canola-wheat-wheat rotations are economically competitive with...

An analysis of the socio-economic factors influencing the adoption of conservation agriculture as a climate change mitigation activity in Australian dryland grain production

Rochecouste, Jean-Francois; Dargusch, Paul; Cameron, Donald - In: Agricultural Systems 135 (2015) C, pp. 20-30

The cropping sector in Australia contributes 2.5% of national greenhouse gas emissions, not accounting for the historical loss of soil carbon. The Australian Government is developing policy initiatives targeted at farmers to encourage changes in management practices that aim to reduce emissions...

The environmental effects of crop price increases: Nitrogen losses in the U.S. Corn Belt

Hendricks, Nathan P.; Sinnathamby, Sumathy; … - In: Journal of Environmental Economics and Management 68 (2014) 3, pp. 507-526

High corn prices cause farmers to plant more corn on fields that were planted to corn in the previous year, rather than alternating between corn and soybeans. Cultivating corn after corn requires greater nitrogen fertilizer and some of this nitrogen flows into waterways and causes environmental...

Combinatorial optimisation of a large, constrained simulation model: an application of compressed annealing

Doole, Graeme J.; Pannell, David J. - Australian Agricultural and Resource Economics Society … - 2007

Simulation models are valuable tools in the analysis of complex, highly constrained economic systems unsuitable for solution by mathematical programming. However, model size may hamper the efforts of practitioners to efficiently identify the most valuable configurations. This paper investigates...

The persistence of drought impacts across growing seasons: a dynamic stochastic analysis

Peck, Dannele E.; Adams, Richard M. - European Association of Agricultural Economists - EAAE - 2007

Agricultural producers throughout much of the United States experienced one of the most severe droughts in the last 100 years during the years 1999-2006. The prolonged nature of this drought highlights a need to better understand the impacts and management of drought across growing seasons,...
