Changing land use patterns in Cass County, Nebraska 1941-1971

This thesis is a study of the changing land use patterns of Cass County, Nebraska. Data for this thesis was obtained from government agencies and field research conducted by the author. The economic base of the county has traditionally been agriculture and agriculture continues to comprise the largest single occupation in the county. Average farm size is increasing, a trend which will continue to reduce the number of smaller, family operated farms. Although the number of inarms has been steadily declining, the value of land and per capita income has been rising. In terms of value received, cattle raising has now exceeded crop cultivation in the area. While corn has remained the major crop, sorghum and soybeans have become increasingly more important, and the traditional wheat production has steadily declined. Low prices and government policy have forced the tiller of the soil to make changes in land use. Limestone quarrying and processing are second only to agriculture in land utilization and in the order of economic importance Government involvement in maintaining the county\u27s natural resources is evident throughout the county. Conservation is practiced energetically by the majority of farmers with the help of government subsidies. Urban, conservation, and industrial land uses are examined because such uses have removed land from agricultural classification. However, the primary focus of this study was upon the agricultural land use changes and related phenomena in the county

N-(4-Chloro­pyridin-2-yl)-N-(4-methyl­phenyl­sulfon­yl)acetamide

The crystal structure of the title compound, C14H13ClN2O3S, features a three-dimensional network stabilized by inter­molecular C—H⋯O hydrogen bonds between the mol­ecules. The 4-methyl­phenyl­sulfonyl ring forms a dihedral angle of 30.6 (1)° with the 4-chloro­pyridine ring

4-Chloro-1-(4-methyl­phenyl­sulfon­yl)-1H-pyrrolo[2,3-b]pyridine

The crystal structure of the title compound, C14H11ClN2O2S, features a three-dimensional network stabilized by π–π inter­actions between the rings of the 4-methyl­phenyl­sulfonyl protecting group [centroid–centroid distance = 3.623 (1) Å]. The 4-methyl­phenyl­sulfonyl ring makes a dihedral angle of 79.60 (6)° with the 4-chloro-1H-pyrrolo[2,3-b]pyridine unit

N-(4-Chloro­pyridin-2-yl)-N-meth­oxy­methyl-4-methyl­benzene­sulfonamide

In the crystal structure of the title compound, C14H15ClN2O3S, each mol­ecule is connected via inter­molecular C—H⋯O hydrogen bonds to three further mol­ecules, generating a three-dimensional network. The 4-methyl­phenyl­sulfonyl ring forms a dihedral angle of 40.7 (2)° with the 4-chloro­pyridine ring

2-(3,4,5-Trimethoxy­phen­yl)-1H-pyrrolo[2,3-b]pyridine

In the title compound, C16H16N2O3, the 3,4,5-trimethoxy­phenyl group makes a dihedral angle of 10.04 (7)° toward the 1H-pyrrolo[2,3-b]pyridine system. The crystal structure displays inter­molecular N—H⋯N hydrogen bonds, forming inversion dimers

4-(4-Fluoro­phen­yl)-1-methoxy­methyl-2-phenyl-1H-imidazole

In the crystal structure of the title compound, C17H15FN2O, the mol­ecules form a three-dimensional network stabilized by π–π inter­actions between two imidazole rings related by a centre of symmetry. The distance between the centroids is 3.5488 (8) Å. The imidazole ring makes dihedral angles of 14.30 (7) and 33.39 (7)° with the 4-fluoro­phenyl ring and the phenyl ring, respectively
