Brazil has become a strong competitor in world soybean production. In 2014, Brazil produced 28% of the world’s soybeans, while the United States produced 34%. Brazil increased its production sharply during the 1990s and 2000s, partly due to the expansion into the Amazon forest region. Soybean was one of the main commodities that led to this expansion. In 2016, the Legal Amazon region produced 33% of the Brazilian soybean production compared to 15% in 1990 (Figure 1).

Little work has been done to determine the relationship between modularity and chemical defense induction against herbivory in herbaceous plant species. We investigated this topic using Asclepias syriaca, common milkweed, and one of its specialist aphid herbivores, Aphis nerii. We studied milkweeds of varying modularities growing in the prairies of Pierce Cedar Creek Institute in Hastings, MI and introduced A. nerii to the plants, monitoring growth of plants and aphid populations over time. After A. syriaca leaves and A. nerii were harvested from study sites, leaf samples from aphid and control treatments were analyzed to measure variation with degree of …

The Ethanol Renewable Identification Number Price Fight And Nebraska Agriculture, Richard K. Perrin
Cornhusker Economics
The petroleum industry has launched a fierce political fight against the Renewable Fuel Standard (RFS), the regulations that require renewable fuels such as ethanol to be blended into the motor fuel supply. The industry complains that meeting those requirements has become too expensive. President Trump has been presiding over frequent White House meetings to address the issue, with corn-state senators leading corn/ ethanol constituents in confrontation with Texas senators leading the petroleum refiners.
