Sedimentation And Diffusion Coefficients Of Legoglobin Fractions, Alfonso R. Trujillo
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The preparation of root nodule extract by Virtanen, et. al., has created a good deal of interest in the study of plant hemoglobin (legoglobin). In the preparation of any new substances, it is of interest to determine the physical constants of the new species.
The Mineral Content Of Various Sections Of Some Plants As Influenced By Conditions Associated With Lime-Induced Chlorosis, Hyrum Del Var Petersen
The Mineral Content Of Various Sections Of Some Plants As Influenced By Conditions Associated With Lime-Induced Chlorosis, Hyrum Del Var Petersen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The so-called "lime-induced" chlorosis has been recognized for many years as a problem where plants are grown on calcareous soils. The characteristics associated with lime-induced chlorosis are the same as those associated with iron deficiency chlorosis--interveinal yellowing of the leaves at the meristemic region combined with reduced vigor of the plant as a whole. Lime-induced chlorosis is unique in that the iron content of both chlorotic plant and the soil do not always show a deficiency in iron when chemically analyzed. This leads to the theory that iron is inactivated in both the soil and plant.
Although no single factor …

Phosphorus Status Of Genola Soils In Utah, Warren E. Bendixen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
With increasing pressure on economical production of crops, more fertilizers are being applied to the soil each year to increase crop yields. Economical production of crops with applications of fertilizer requires an evaluation of the essential elements of the various crops so applications of fertilizer will not exceed the law of diminishing returns.
Because varying soil, moisture, and climatic conditions influence the response to added fertilizers, some workers (18, 26, 38) have contended that the only reliable way of determining the fertilization needs of a crop is to conduct a trial on the particular farm. The length of time involved …
