The Long-Term Fate Of Copper Fertilizer Applied To A Lateritic Sandy Soil In Western Australia, R. G. Mclaren, G. S.P. Ritchie Jan 1993

The Long-Term Fate Of Copper Fertilizer Applied To A Lateritic Sandy Soil In Western Australia, R. G. Mclaren, G. S.P. Ritchie

Food Science and Nutrition

A soil copper fractionation was carried out on soils sampled from plots in a long-term copper fertilizer trial on a lateritic sandy soil in Western Australia. At copper application rates up to 8.25 kg copper sulphate ha-1, a high proportion of the applied copper was initially associated with the soil organic matter. During the course of the trial (20 years), a substantial proportion of this copper became redistributed to a residual soil fraction, i.e. the residue remaining after extractions to remove organic matter and iron oxides. However, significant redistribution of copper with time was not detected in plots …

H+/Oh- Excretion And Nutrient Uptake In Upper And Lower Parts Of Lupin (Lupinus Angustifolius L.) Root Systems, S. P. Loss, A. D. Robson, G. S.P. Ritchie Jan 1993

H+/Oh- Excretion And Nutrient Uptake In Upper And Lower Parts Of Lupin (Lupinus Angustifolius L.) Root Systems, S. P. Loss, A. D. Robson, G. S.P. Ritchie

Food Science and Nutrition

The cultivation of narrow-leafed lupins (Lupinus angustifolius L.) increase rates of subsoil acidification, and this is thought to be partly related to their pattern of nutrient uptake and H+/OH- excretion. The main hypothesis of this study was that H+ and OH- excretion is not distributed evenly over the entire length of the root system but is limited to zones where excess cation or anion uptake occur. Seedlings of nodulated lupins were grown in solution culture using vertically split pots that allowed the upper and lower zones of the root system to be supplied with …

Office of the President Scholarship

We have utilized active immunization against growth hormone releasing factor (GRF) to investigate relationships among somatotropin (ST), insulin-like growth factor-I (IGF-I), IGF binding proteins (IGFBP) and ovarian function in heifers. Active immunization against GRF (GRFi) has been demonstrated to abolish episodic release of ST and decrease serum concentrations of IGF-I. In initial experiments investigating onset of puberty, breeds of heifers differing in growth rate and reproductive traits (Angus, Charolais and Simmental) were immunized against GRF or served as controls (immunized against carrier protein, human serum albumin, HSAi). GRFi decreased rate of muscle and skeletal growth, but increased deposition of adipose …

Utilizing Iron In Turfgrass Management, David J. Wehner Jul 1992

Utilizing Iron In Turfgrass Management, David J. Wehner

Office of the Dean (CAFES) Scholarship

The purpose of this article is to review some of the basic information on iron, look at one of the discoveries made during the 1980s, and present some of the published research studies that have been conducted with iron on turfgrasses. Additional information on the use of iron can be found in popular magazines and in the proceedings of turfgrass conferences.

Giant Sequoia Insect, Disease, And Ecosystem Interactions, Douglas D. Piirto Jun 1992

Giant Sequoia Insect, Disease, And Ecosystem Interactions, Douglas D. Piirto

Natural Resources Management and Environmental Sciences

Individual trees of giant sequoia (Sequoia gigantea [Lindl.] Decne.) have demonstrated a capacity to attain both a long life and very large size. It is not uncommon to find old-growth giant sequoia trees in their native range that are 1,500 years old and over 15 feet in diameter at breast height. The ability of individual giant sequoia trees to survive over such long periods of time has often been attributed to the species high resistance to disease, insect, and fire damage. Such a statement, however, is a gross oversimplification, given broader ecosystem and temporal interactions. For example, why isn't …
