Test 1752: Agco Allis 9745 Diesel 18-Speed, Nebraska Tractor Test Lab
Test 1752: Agco Allis 9745 Diesel 18-Speed, Nebraska Tractor Test Lab
Nebraska Tractor Tests
EXPLANATION OF THE TEST PROCEDURE
General
Tractors are tested at the University of Nebraska according to the Agricultural Tractor Test Code approved by the American Society of Agricultural Engineers and the Society of Automotive Engineers or official Nebraska test procedure.
The manufacturer selects the tractor to be tested and certifies that it is a stock model. Each tractor is equipped with the common power consuming accessories such as power steering, power lift pump, generator, etc., if available. Power consuming accessories may be disconnected only when the means for disconnecting can be reached from the operating station. An official representative of …

Leafy Spurge (Euphorbia Esula L.) Spread In Iowa, S. C. Huerd, S. E. Taylor
Leafy Spurge (Euphorbia Esula L.) Spread In Iowa, S. C. Huerd, S. E. Taylor
Journal of the Iowa Academy of Science: JIAS
Leafy spurge (Euphorbia esula L.), a noxious perennial weed spreading south from the northern Great Plains into Iowa, is considered a threat to Iowa's Prairie preserves because it is an aggressive non-native plant that dominates the landscape through rapid sexual and asexual reproduction. Methods to control leafy spurge include cultural and chemical controls, and biological controls are currently being developed. In 1992 and 1993 we surveyed the extent of leafy spurge spread in Iowa and found 26 of 99 Iowa counties with leafy spurge populations. Iowa's leafy spurge populations are rapidly expanding on untilled lands such as roadsides, especially in …
Book Review - Birds In Iowa, Peter Wickham
Book Review - Birds In Iowa, Peter Wickham
Journal of the Iowa Academy of Science: JIAS
Here is a book that those who are interested in birds and their distribution in Iowa will absolutely have to possess. This volume is the successor to the book Iowa Birds, which was written by the above authors together with three others and published in 1984. It brings our understanding to the number of species of birds and their relative abundance in Iowa up-to-date. Although only twelve years elapsed between the publication of the previous volume and this one, the activity of those interested in identifying birds increased enormously during those years. In addition, their ability to identify and find …
Status Of Aquatic Vascular Plants 1n Iowa's Natural Lakes, G. S. Phillips
Status Of Aquatic Vascular Plants 1n Iowa's Natural Lakes, G. S. Phillips
Journal of the Iowa Academy of Science: JIAS
Conversion of wetlands to agricultural land during the settlement of Iowa has resulted in a significant decline in the total area of lake habitat in the state. This reduction in area, combined with the degradation of remaining sites, resulted in dramatic reductions in aquatic vascular plant populations associated with Iowa's natural lakes. While declines in plant species inhabiting fen, bog, seepage, prairie pothole, and marsh type wetlands have been extensively documented, few quantitative data exist for lake type wetlands. During the summer of 1996, a total of 86 natural lakes in Iowa were surveyed for aquatic vascular plants. Many of …
Iowa's Odonata: Declining And/Or Changing?, Robert W. Cruden, O. J. Gode Jr.
Iowa's Odonata: Declining And/Or Changing?, Robert W. Cruden, O. J. Gode Jr.
Journal of the Iowa Academy of Science: JIAS
We undertook a comprehensive survey of the Order Odonata in Iowa. Because the credibility of our conclusions derives from our collecting strategy and effort, we discuss our strategy in depth. We collected throughout the state (more than 500 sites in 94 counties), throughout the flight season (late May-early October), and tried to visit several habitats in each county. Our 7900+ observations made between 1993 and 1996 include approximately 2300 county records, 93 of the 110 species reported for the state, and eight species previously unknown from the state. At least 30 species are secure and occur across the state. Other …
