New Rules, New Technologies, And The Shape Of Minnesota Farming, Steven J. Taff
New Rules, New Technologies, And The Shape Of Minnesota Farming, Steven J. Taff
Journal of the Minnesota Academy of Science
The future development of Minnesota agriculture will be strongly influenced by new technologies and government policies that will alter prices for farm inputs and outputs. While some farm operations will fail under most expected price regimes, a loss of farmers will probably not have a significant impact on overall farm production. However, the new technologies and government policies could shift Minnesota farming into either a more intensive (less land, higher yield) or more extensive (more land, lower yield) mode of operation. A shift either way will have important implications for Minnesotans. Ownership and residence patterns, ground water quality, habitat and …

Global Agricultural Trade Negotiations And Their Potential Impact On Minnesota, Mark Ritchie
Journal of the Minnesota Academy of Science
The two main factors determining the financial well-being of our family farmers, market prices and government payments, are primarily established by Congress through federal legislation, commonly called the Farm Bill. Although these two factors are likely to remain the main economic ingredients in Minnesota's farm economy for the foreseeable future, the political control over these issues appears to be shifting out of the hands of Congress and into the hands of our international trade negotiators. For the very first time, all price support, income subsidy, and supply management programs are on the table for alteration or elimination in this new …
Hexagenia Mayflies: Biological Monitors Of Water Quality In The Upper Mississippi River, Calvin R. Fremling
Hexagenia Mayflies: Biological Monitors Of Water Quality In The Upper Mississippi River, Calvin R. Fremling
Journal of the Minnesota Academy of Science
ABSTRACT-Analysis of Hexageniamayfiy distribution patterns has proven to be a simple, inexpensive method of monitoring water quality in the Upper Mississippi River. Burrowing Hexagenia nymphs live at the mudwater interface intimately associated with organically enriched sediments that have a strong affinity for contaminants. By their presence or absence in silted habitats, they assess the synergistic effects of hypoxia, toxins, and other stresses throughout the year. Adults are large and easily collected, providing inexpensive water quality monitoring on a river so large that comprehensive chemical, physical, and biological analyses are not logistically feasible or affordable. Pollution abatement in metropolitan Minneapolis-St. Paul …
