INCENTIVES FOR SWITCHING AGRICULTURAL LAND TO CARBON SEQUESTERING NO-TILLAGE:  WHAT DURATION ARE INCENTIVES NECESSARY?
Provedor de dados: 31
Autores: Hellwinckel,   Chad M.; Larson,   James A.; Torre Ugarte,   Daniel de la.
Fourteen long term side-by-side tillage practice experiments were studied to analyze if no-tillage yields improved through time allowing incentives to decline.  In the majority of cases, no significant increase in no-till yield is evident.  Incentives may need to be permanent if switched acres are to remain using no-tillage practices.

The Renewable Fuel Standard mandates in the Energy Independence and Security Act of 2007 will require 36 billion gallons of ethanol to be produced in 2022. The mandates require that 16 of the 36 billion gallons must be produced from cellulosic feedstocks. The potential land use implications resulting from these mandates were examined using two methods, the POLYSYS model and a general equilibrium model. Results of the POLYSYS analysis indicated that 72.1 million tons of corn stover, 23.5 million tons of wheat straw, and 24.7 million acres would be used to produce 109 million tons of switchgrass in 2025 to meet the mandate. Results of the CGE analysis indicated that 10.9 billion bushels of corn grain, 71 million tons of corn stover, and 56,200 tons of...

Economic Competitiveness of Bioenergy Production and Effects on Agriculture of the Southern Region
Provedor de dados: 31
Autores: English,   Burton C.; Torre Ugarte,   Daniel de la; Walsh,   Marie E.; Hellwinckel,   Chad M.; Menard,   R. Jamey.
The economic competitiveness of biobased industries is discussed by comparing the South relative to other regions of the United States and biomass as a feedstock source relative to fossil fuels such as coal and petroleum.  An estimate of the biomass resource base is provided.  Estimated changes in the agricultural sector over time resulting from the development of a large-scale biobased industry are reported, and a study on the potential to produce electricity from biomass compared with coal in the southern United States is reviewed.  A biobased industry can increase net farm income and enhance economics development and job creation.

Agricultural Impacts of Biofuels Production
Provedor de dados: 31
Autores: Walsh,   Marie E.; Torre Ugarte,   Daniel de la; English,   Burton C.; Jensen,   Kimberly L.; Hellwinckel,   Chad M.; Menard,   R. Jamey; Nelson,   Richard G.
Analysis of the potential to supply 25% of projected 2025 U.S. transportation fuels indicates sufficient biomass resources are available to meet increased demand while simultaneously meeting food, feed, and export needs. Corn and soybeans continue to be important feedstocks for ethanol and biodiesel production, but cellulose feedstocks (agricultural crop residues, energy crops such as switchgrass, and forestry residues) will play a major role. Farm income increases, mostly because of higher crop prices. Increased crop prices increase the cost of producing biofuels.

This study evaluated the risk management potential of including biomass crops as a diversification strategy for a grain farm in northwest Tennessee.  Results indicate that adding biomass crops to the farm enterprise mix could improve mean net revenues and reduced net revenue variability.
