Microbial Characteristics Of An Industrial Mixed Liquor After Exposure To Phenolic Compounds, Patricia L. Boyle
Theses
The microbial characteristics of a mixed population from the Passaic Valley Sewerage Commissioners (PVSC) Wastewater Treatment Plant in Newark were examined. This plant handles about 250 million gallons per day of mixed sewerage, with a large industrial component. The microbial species were characterized using standard plating techniques, morphology, microscopic observation, and biochemical tests. These characteristics were determined for the fresh liquor, and after successive batch exposure to phenol (100 ppm) and 2-chlorophenol (20 ppm). Predator/prey, gram positive to gram negative bacteria ratios, and the fungi and protozoan populations were also determined. These results were compared with those previously obtained using …

Wildlife Damage Control And The Wildlife Society, Thomas M. Franklin
Eastern Wildlife Damage Control Conference: 2nd (1985)
Wildlife damage control is recognized by The Wildlife Society as an essential and responsible segment of the wildlife profession. At least since 1959, Society committees have addressed elements of wildlife damage control (although wildlife damage control was not always the specific term used). The Wildlife Society Council first approved an "Animal Damage Control" position statement in 1968. In March 1985, Council updated and renamed it "Wildlife Damage Control" to emphasize our positive approach to this important segment of wildlife management. The official position statement was published in The Wildlifer (May-June 1985) and is reprinted below.

Pollution In The Mediterranean: A Regional Response, Antony O. Heimer
Marine Affairs Theses and Major Papers
Pollution of the Mediterranean Sea has been an issue of significant political, economic and environmental concern for more than a decade. It has more recently become a regional issue with politically diverse coastal states and a wide variety of international agencies implementing cooperative programs of scientific research, education and training, planning, and treaty drafting. Being a regional issue, the pollution problem has facilitated discussions between nations on several levels and governments have found it politically advantageous to use the issue for a variety of purposes.This paper will provide an overview of the Mediterranean pollution problem, covering the nature of the …

Laser Levelling Land For Flood Irrigation, M D. Green, J. P. Middlemas
Laser Levelling Land For Flood Irrigation, M D. Green, J. P. Middlemas
Journal of the Department of Agriculture, Western Australia, Series 4
Since the introduction of laser levelling to Western Australia's South-West irrigation area five years ago, many farmers have benefited from this new and precise method of land-forming.
The use of lasser controlled earthmoving equipment to redevelop irrigated paddocks has led to improved irrigation efficiency and drainage. Less water is used for each irrigation, water is applied more evenly and less labour is needed. many older, grass-dominated paddocks have been reseeded to improve pasture species.
Eradicating Fruit Fly From Carnarvon, Kingsley Thomas Fisher
Eradicating Fruit Fly From Carnarvon, Kingsley Thomas Fisher
Journal of the Department of Agriculture, Western Australia, Series 4
Late last year the Mediteranean fruit fly (Ceratitis capitata Weidemann) was eradicated from Canarvon, Western Australia by using an intergrated programme of sterile insect releases and bait spraying.
The eradication marked the end of a four-year study on the use and effectiveness of the Sterile Insect Technique, a biological control technique which uses an insect pest against itself. such a study can be used as a basis for treating other threatening insect pests, such as the serious cattle pest screw-worm fly, should they be found in Asustralia.
Being a biological control method, the Sterile Insect Technique is an exellent …
Water Quality For Irrigation, P R. George
Water Quality For Irrigation, P R. George
Journal of the Department of Agriculture, Western Australia, Series 4
Although irrigation and salinity problems are frequently inseperable, there is a range of management methods that can be used to handle marginal quality water. Freuently these methods are simple, but require careful planning.
The wide range in tolerance of crops to salinity can be exploiter to ensure that appropriate crops are selected for the water available.
Because crops vary in their sensitivity to salt uptake in the leaves or the roots, watering methods can be changed to avoid problems. For profitable production enough water should be applied to ensure adequate water is available for plant growth as well as to …
Salinity Control In Northern China, G A. Robertson
Salinity Control In Northern China, G A. Robertson
Journal of the Department of Agriculture, Western Australia, Series 4
China has vast areas of saline land, perhaps as much as six million hectares. Some of this saline land is a result of marine influence in coastal areas and some is the resultof soil formation in areas with saline geological deposits and inadequate rainfall to leach out the salts at that time.
However, most saline soils in China are as a result of secondary salinisation processess induced by a hydrological imbalance resulting from over-clearing of the land or irrigation. This imbalance has produced rising watertables bringing the salt closer to the soil surface.
In this article, G..A. Robertson, Commissioner …
Residual Values Of Australian Rock Phosphates, Michael D A Bolland
Residual Values Of Australian Rock Phosphates, Michael D A Bolland
Journal of the Department of Agriculture, Western Australia, Series 4
For years superphosphate has been the cheapest, convenient and most effective way of supplying phosphorus to newly cleared soils in Western Australia's South-West that are acutely deficient in phosphorus. However its effectiveness as a phosphorus source falls markedly after application. Regular applications are needed to maintaine profitable pastures and crops on these soils.
After a big jump in supperphosphate prices in the mid 970s, researchers tested the use of Australian rock phosphates as potentially cheaper alternative phosphorus fertilisers to superphosphate. On the none-leaching sands, as this article shows, none of the rock phosphates was as effective for plant growth as …

The Inapplicability Of The Concept Of The "Sidney Gravel" To The Ogallala Group (Late Tertiary) In Part Of Southern Banner County, Nebraska, Robert F. Diffendal Jr.
School of Natural Resources: Faculty Publications
A series of geologic maps of counties in western Nebraska was prepared for the Nebraska Geological Survey during the mid-1 930s. These maps showed the distribution of rock units of Tertiary age including a formation designated as the “Sidney.” The Sidney Gravel was described as a widespread sheetlike complex of channel deposits, but with small areas where it is not developed. In southern Banner County, Nebraska, there are several channels filled with sand and gravel that were mapped as Sidney in this series. Recently one of these channel fills has been observed to cut across the other. The fills are …

Characteristics, Age Relationships, And Regional Importance Of Some Cenozoic Paleovalleys, Southern Nebraska Panhandle, Robert F. Diffendal Jr., James B. Swinehart, J. J. Gottula
School of Natural Resources: Faculty Publications
Few workers have reported previously on features of ancient valleys in western Nebraska. Six sites in the southern Nebraska Panhandle, ranging in age from Oligocene to Middle to Late Pleistocene, illustrate the characteristics and variability of Cenozoic paleovalleys. The dimensions of these paleovalleys vary from less than 0.1 km to more than 1.0 km in width and from less than 1.0 km to more than 100 km in length. Relief is as much as 35 m in outcrop. Four of the examples have valley sides that are nearly vertical. Potholes and other scour features occur at one site. Remnants of …

The Green Movement: Implications For Animals, Ronnie Z. Hawkins
Environment Collection
The Green movement, a newly emerging political movement that is both global in scope and firmly anchored to each local region at the grassroots level, is destined to be of great import to those concerned with the status of nonhuman animals in our society. Closely allied with deep ecology and bioregionalism, Green thinking embodies an alteration in our perception of the human organism: no longer seen as separate from and superior to all the other components of the ecosystem, our species is placed in context as one among many interdependent forms of life, with the attainment of a sustainable balance …

Underground Water Supplies In The Wheatbelt, T T. Bestow
Underground Water Supplies In The Wheatbelt, T T. Bestow
Journal of the Department of Agriculture, Western Australia, Series 4
Underground water originates from rainfall. The size of the underground recource in any region is broadly related to the amount of rainfall. However, rainfall intensity and seasonal distribution are just as importent as the quality. A relatively small annual fall which consists of a series of heasvy showers or storms close together, may be a more effective source of recharge to underground water than a larger fall that is more evenly distributed over a longer period.
A large annual rainfall, however, is no guarantee that underground water supplies will be readily available. This is because soils and the underlying rocks …
Improved Catchments For Farm Dams, I A F Laing
Improved Catchments For Farm Dams, I A F Laing
Journal of the Department of Agriculture, Western Australia, Series 4
The amounts and frequency of runoff from unimproved farmland catchments in Western Australia's cereal and sheep districts are notoriously variable and unreliable. As a result many farmers have constructed improved catchments to ensure better reliability of farm dams for livestock and homestead water supplies.
Improved catchments which are used extensively on these farms are all of the compacted or bare-earth type. These include roaded catchments, flat batter dams and, to a lesser extent, scraped catchments. This article mainly discusses roaded catchments, the most common of the improved catchment types on farms.
Chemical Sealing Of Earth Dams, R G. Pepper
Chemical Sealing Of Earth Dams, R G. Pepper
Journal of the Department of Agriculture, Western Australia, Series 4
Leakage is not a major cause of failure of farm dams in the Western Australian wheatbelt, but it is a problem in some districts where it can limit stock carrying capacity. Leaking dams are especially common in the West midlands, the north-eastern wheatbelt and the 'jarrah-belt' which extends from Bindoon, southward to Manjimup and Mt Barker (see map and Table 1).
Some dams which leaked when first built have sealed themselves over the years. Others have been successfully sealed using sodium tripolyphosphate.
Dam Site Selection In The North-Eastern Wheatbelt, J L. Frith
Dam Site Selection In The North-Eastern Wheatbelt, J L. Frith
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australia's wheatbelt farm dams are dug three to eight metres deep and are generally sited in soils which either are inherently impermeable or can be made so during construction.
In the eastern and north-eastern wheatbelt, however, only a small proportion of the soils meets these criteria. Dam site selection in these areas therefore depends on a good knowledge ofwhich soils aresuitable and on our being able to locate them efficiently by using surface indications such as surface soil, natural vegetation or topographic features.
Drought Proofing The Farm : Case Studies, J L. Frith
Drought Proofing The Farm : Case Studies, J L. Frith
Journal of the Department of Agriculture, Western Australia, Series 4
For many years, Western Australia's north-eastern wheatbelthas suffered chronic shortages of water for stock and domestic use. The area's averageannual rainfall is generally low - less than 300 millimetres - and droughts in the 1970s caused futher problems. manydams in the area leak or have inadequate catchmentsand groundwater is scarce ormofmpoor quality.
In March 982, the Western Australian Government provided $100 000 for the Department of agriculture to demonstrate the potential of establishing permanent, drought-proof water supplies on farms in the north-eastern wheatbelt. The methods were to use exixting techniques to build dams and catchments. In a year of low …
