Research : Co-Operation Is The New Style, John Hamblin, Ian Maling

Journal of the Department of Agriculture, Western Australia, Series 4

Co-operative Research Centres, or CRCs as they are known, are a new trend in agricultural research. Instead of organisations such as Departments of Agriculture or universities pursuing their own individual research projects, sometimes in competition or covering similar fields, the idea is to combine talents and expertise. CRCs were a Federal Government initiative launched in 1990, and the Centre for Legumes in Mediterranean Agriculture was the first involving agriculture in Western Australia.

Using Saltland In Pakistan : An Australian Connection, Ed Barrett-Lennard, Riaz Qureshi

Journal of the Department of Agriculture, Western Australia, Series 4

Pakistan and Australia have a common enemy in salt. In each country millions of hectares of previously productive land have been affected by salt (or have the potential to become saline) because of inappropriate agricultural development. Since 1989 the Western Australian Department of Agriculture has participated in a research project in Pakistan which involves revegetation of salt land using Australian shrubs. Early results are very promising.

Influence Of Reduced Leaching On Growth Of Seedlings Of Black Locust Inoculated With Rhizobia, William R. Graves, Sandra R. Anfinson

Journal of the Iowa Academy of Science: JIAS

Seedlings of black locust (Robinia pseudoacacia L.) were inoculated with compatible rhizobia and irrigated twice each week with solution containing either 50 or 150 mg nitrogen/L. Leaching fraction treatments of 0, 0.2, or 0.4 were maintained for 6 weeks. Seedlings supplied 50 mg nitrogen/L grew poorly compared co planes supplied 150 mg nitrogen/L regardless of leaching fraction. Dry masses of shoots and of entire planes were lower for seedlings in the 0 and 0.2 leaching fraction treatments compared with chose in the 0.4 treatment. Neither leaching fraction nor applied nitrogen concentration appeared co affect the number of nodules per plant, …

Age And Developmental History Of Iowa Fens, C. A. Thompson, E. A. Bettis Iii

Journal of the Iowa Academy of Science: JIAS

Iowa fens are small, mineorotrophic peatlands maintained by shallow groundwater. Eighteen fen sites located across northern Iowa were mapped and radiocarbon dated to assess the timing of initial peat accumulation. The radiocarbon ages span the Holocene, ranging from 1,240 to 10,900 B.P.; however most fens postdate 5,000 yr B.P. The dominance of late-Holocene ages suggests that Holocene climatic change may have strongly influenced the record of peat accumulation. During the mid-Holocene Iowa was warmer and drier than at present, and peat was degraded or accumulated slowly in fens. The range of ages also implies that the commencement and subsequent rate …

The farm continues to serve as a primary source of income for the Academy and a …

Post-Natal Survival Of Raccoons In Relation To Female Age And Denning Behavior, Jonathan J. Judson, William R. Clark, Ronald D. Andrews

Journal of the Iowa Academy of Science: JIAS

We measured post-natal survival of radio-collared raccoons 1-5 months old in southwest Iowa, 1988-1989. We compared survival of young nurtured by yearling and adult females and related den site selection to survival functions using proportional hazards models. Adult females used upland and farmstead habitats note frequently than yearlings, whereas yearling females used lowland habitats note frequently. Tree cavities and beds on the ground were used most frequently. Adult females denned in buildings 13% of the time and in holes in the ground 9.5% of the time, whereas yearlings frequently tested with litters in beds on the ground (31%). Microhab1tat characteristics …

Effects Of Competition And Predation On Prothonotary Warblers And House Wrens Nesting In Eastern Iowa, Timothy Brush

Journal of the Iowa Academy of Science: JIAS

In a fragmented midwestern floodplain forest, a small Prothonotary Warbler (Protonotaria citrea) population experienced high competition with House Wrens (Troglodytes aedon) and mammalian nest predation in 1988-89. Despite the provision of 3 types of nest boxes and higher water levels, Prothonotary Warblers did not nest successfully and decreased in the fragmented forest in 1990-91. House Wrens used >90% of the nest boxes in both years. Wren territories doubled within the nestbox area, while remaining constant on an unmanipulated area. In contrast, a larger warbler population had high nesting success during 1990-91 in a relatively unfragmented, wetter forest tract. Such forests, …

Crystal Structure Of An Iodine Phenazine Complex: C12h9n2 + · I3-. C12h8n2 · 1/6i2, Rebecca A. Brandenburg, Sharon L. Ringrose, Robert A. Jacobson

Journal of the Iowa Academy of Science: JIAS

A structural study of the polyiodide containing species C₁₂H₉N₂⁺ I₃^- C₁₂H₈N₂ · 1/6I₂ was carried out by single crystal X-ray diffraction techniques. The material crystallizes in the monoclinic space group C2/m with a= 16.561(5), b = 8.372(2), c = 9.908(5) A and β = 111.24°. There are two molecules per cell. Dara were collected using Mo K_ἀ radiation and refinement converged to R = 0.027 based on the 1996 unique reflections with |F_o|≥3δ(F_o). The iodine atoms were found coexist in two …

Removal Of Magnetic Impurities From Strontium Copper Oxychloride, Colleen B. Eads, Carol J. Kosmicke, Lance L. Miller

Journal of the Iowa Academy of Science: JIAS

Analyses of a copper-deficient series of Strontium Copper Oxychloride polycrystalline samples are reported. Magnetic susceptibility, X-ray powder diffraction, and differential thermal analyses show a small Curie-type magnetic signal correlates with =0.6% (excess) copper ions in the nominally stoichiometric material. The analyses also imply that the extra magnetic signal is from an impurity phase, possibly related to Strontium Copper Oxide. The concentration of the impurity phase can be controlled by varying the copper stoichiometry.

Testing The Accuracy And Precision Of Wetness Sensors In A Tomato Field And On Turfgrass, Kara J. Potratz, Mark L. Gleason, Melanie L. Hockmuth, Sharon K. Parker, Glenn A. Pearston

Journal of the Iowa Academy of Science: JIAS

Measurements of dew-period duration by painted, flat-plate, electronic wetness sensors at the top of the plant canopy in a tomato field and on adjacent turfgrass were compared with visual observations. The response range of sensors during the onset of dew sometimes exceeded 5 hr. but was less than 1 hr. on other nights. Sensors in the tomato field indicated dew formation occurred as much as 2 hr. earlier or later than dew became visible on adjacent tomato leaflets at the top of the crop canopy. A calibration threshold for sensors derived from a drying curve resulted in the underestimation of …

Soybean Residual Effects On A Subsequent Maize Crop, E. S. Escuro, D. N. Sundberg, R. M. Shibles

Journal of the Iowa Academy of Science: JIAS

Maize (Zea mays 1.) grown after soybean (Glycine max 1. Merr.) consistently performs better than maize that follows itself (second year maize), irrespective of nitrogen fertilization. In previous studies of the soybean-maize rotation, there never has been an evaluation of the potentially different effects of soybean genotypes on following maize. A two-year, soybean maize rotation was initiated in Ames at 1988 with the first year planted to various soybean genotypes, a maize hybrid, and oat (Avena sativa 1.). These were followed in the second year by a single maize hybrid with 0, 80, 160, and 240 kg/ha N fertilization levels. …
