Agronomy Notes
About three-fourths of Kentucky's cropland base occurs on sloping land with some degree of erosion hazard. During the past decade, production of soybeans and corn increased rapidly in Kentucky, particularly on sloping land. This resulted in severe erosion on many farms, particularly in the "intensive grain producing counties. Much of this field erosion could be greatly reduced by developing a system for each field that would incorporate use of such agronomic practices as sod waterways, no-till planting, contour plowing, minimum tillage, strip cropping, double-cropping, winter cover crops, crop residue management and rotations. It is believed that the current acreage of …

Ada Hayden: A Tribute, Duane Isely
Journal of the Iowa Academy of Science: JIAS
Dr. Ada Hayden was a member of the Iowa State College of Botany faculty, 1920-1950. Her floristic studies of the lake region in northern Iowa are possibly the most authoritative for any part of the state. Hayden was curator of the Iowa State herbarium, 1934-1950, and contributed immeasurably to its development. This research facility has recently been named the Ada Hayden Herbarium. In the sense that L. H. Pammel was father of the Iowa State park system, her bequest is the state preserves. After some 25 years as a conservation activist, she published descriptions of 22 prairie areas in ten …
