The Geographic Distribution Of Azotobacter And Rhizobium Meliloti In Nebraska Soils In Relation To Certain Environmental Factors, H. B. Peterson, T. H. Goodding
The Geographic Distribution Of Azotobacter And Rhizobium Meliloti In Nebraska Soils In Relation To Certain Environmental Factors, H. B. Peterson, T. H. Goodding
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
In this investigation a survey of Nebraska soils has been made in order to determine the distribution of the aerobic nonsymbiotic and symbiotic nitrogen fixers of the genera Azotobacter and Rhizobium respectively. In connection with this survey, some of the characteristics of the soils which may bring about this distribution were studied. Up to this time practically no research has been reported on the microflora of the soils of Nebraska. Hence there is little basis for predicting the activity of these organisms under environmental conditions as they exist here. It is hoped that this work will not only supply some …

Control Of The Chinch Bug In Nebraska, M. H. Swenk, H. D. Tate
Nebraska Agricultural Experiment Station: Historical Circulars
The chinch bug, Blissus leucopterus (Say), is one of the most injurious insect pests of cereal crops in the United States. Although some damage by it has occurred over a wide area in the United States, the greatest injury has been in the Corn Belt. The years in which the chinch bug appears in destructive abundance come irregularly in cycles of varying duration, and the length of these cycles is largely controlled by the direct or indirect effects of weather upon the bugs. Continued dry weather favors them, while very wet weather brings about their destruction. During the last seven …

Bromegrass Production In Nebraska, A. L. Frolik, L. C. Newell
Nebraska Agricultural Experiment Station: Historical Circulars
A native of the old world, from central Europe to China, bromegrass was introduced into the United States about 1884. In 1899, the Nebraska Agricultural Experiment Station reported that "all things considered, it is the most promising cultivated pasture grass for this state that has been tested on the Station farm." Early records of the Station show that considerable seed was distributed to farmers during the period from 1898 to 1902. A few of these early plantings are still in existence. Bromegrass increased in popularity in Nebraska until about 1910. Very little interest was shown in this crop during the …
