Drains : A Method Of Financially Assessing Drains Used To Mitigate Waterlogging In South-Western Australia, John S. Salerian, D J. Mcfarlane

Resource management technical reports

Seepage interceptor drains are often effective in mitigating waterlogging in duplex (sand over clay) soils on hill slopes in the sout-west. Spoon and W drains are sometimes effective in removing excess surface waters form clay flats.

This report outlines a method to determine the long-term (1 to 20 years) cost-effectiveness of installing drains to mitigate waterlogging for each individual situation.

Trials With Trickle Irrigation Equipment At Morogoro Preliminary Report, M.E. Parkes, M. E. Madata

Tanzania Journal of Science

The use of trickle irrigation is discussed with reference to Tanzania. A split-split plot design experiment is described in which yields of tomato, onion, and cabbage are compared for trickle and hand-irrigated plots, with different levels of fertiliser treatment. Yields for trickle-irrigated plots were significantly greater only for tomatoes. These results were achieved during July to October and a second attempt to grow the same vegetables during December to March was unsuccessful. Further trials are required to obtain a suitable rotation of vegetable crops from both a nutritional and agronomic point of view. Experience with the trickle irrigation equipment is …

Land Systems Of The Brockman River Catchments, S. Porritt

Natural resources published reports

The survey was conducted to gain basic information about the agricultural land use of the Brockman River Catchment. The University of Western Australia Faculty of Agriculture was interested in the area as a compact, agriculturally diverse area close to Perth which was, therefore, suitable for filed studies. The Department of Agriculture, Moora Office was interested in this study as a framework within which to improve its extension services in the area.

Both parties cooperated in investigations of the area by providing data and equipment. Field work was carried out in summer 1973-74 and data compiled by an agricultural science student …

Bulletin No 3867 - Water For Agriculture. Clearing Cloudy Or Coloured Water, N. E. Platell

Bulletins - 3000 - 3999

THE suspended material in most water supplies is generally clay, although sometimes organic matter and materials precipitated from solution, such as hydrated iron oxides, may be present. Coloured waters are those waters that are still coloured, due to dissolved coloured matter, after suspended material has been removed. Some coloured waters such as those found in swampy areas may be entirely free of suspended material.

The amount of clay or colour present is mainly of concern where the water is used for household purposes. Only rarely is the clay or colour present in such quantities that the water is undrinkable for …

A Report On The Condition Of The Gascoyne Catchment, D G. Wilcox, E A. Mckinnon

Resource management technical reports

Severe flooding in Carnarvon followed heavy rains on the Gascoyne Catchment in February 1961. The flooding and erosion were extensive enough to suggest that run-off from the catchment was excessive. Lightfoot (1961)* reported that excess run-off was due to degradation of the catchment area. This report will describe the catchment area in terms of the degradation of its rangeland and its susceptibility to erosion.

Don't Crop Areas Liable To Waterlogging, Department Of Agriculture, Western Australia

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

The increasing areas of crops being sown in high rainfall districts make it likely that many crcp areas include sections liable to severe waterlogging.

This report presents results of a 1970 trial which clearly show that sowing such sections is not economic.

Water Conservation Handbook, D J. Carder, G. W. Spencer

Natural resources published reports

This handbook is intended as a practical guide in some of the most common aspects of water conservation in the agricultural areas of Western Australia. It deals mainly with water conserved in dams for stock and domestic purposes on the farm.

the farm. The handbook does not attempt to deal with all aspects of handling and using water for agricultural purposes. This is a vast subject which extends into many fields such as engineering, irrigation and land use.

The guide does, however, touch on some important aspects of good management of agricultural land. It should be read in conjunction with …

Kimberley Research Station : A Progress Report, Department Of Agriculture, Western Australia

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

INTEREST in the agricultural potential of the Kimberley region in Western Australia dates from its early exploration and settlement in the last century.

Several farming development schemes were considered for the area, but were never implemented.

This could be mainly attributable to lack of knowledge of agricultural potentialities, limitations of the local environment and ways of exploiting the local environment.

Up to the present the economy of the region is almost entirely based upon the extensive production of beef and to a lesser extent, wool.

Leaflet No 1003 - The Salt Problem In The Wheat Belt, G. H. Burvill

Bulletins 1 - 2999

IN the wheat belt of Western Australian bare patches in farm paddocks are often seen. Many are bare, or almost bare, because of too much salt in the soil. The excess of salt prevents the germination of seeds, or kills living plants, because it causes the water supply for germination or growth to be cut off. This salt problem is so serious in places that single farms or groups of farms have been ruined; wheat growing on them has become unprofitable.

Plan Of Development For Valley Gravity Project, Julius A. Krug, Michael W. Straus, Wesley R. Nelson

Lower Rio Grande Valley Curated Material

"The Valley Gravity Project Plan has been formulated to furnish an adequate and dependable irrigation water supply for fertile and productive area in the Lower Rio Grande Valley, Texas, It would also provide drainage works, which would remove the threat of destruction of the economy of the area due to effects of a high water table and salt accumulations. The project works would permit generation of the maximum practicable amount of electrical energy which otherwise would be required to operate irrigation pumping plants. Other incidental benefits include fish and wildlife conservation, recreation and flood control."

A Proposed Method For Classifying And Evaluating Soils On The Basis Of Productivity And Use Suitabilities, Arthur Anderson, A. P. Nelson, F. A. Hayes, I. D. Wood

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is the object of this paper to present a method for classifying and evaluating the soils as mapped in regular soil surveys on the basis of land types, which are here defined as areas having reasonably similar productivity and use suitabilities. The standards used to differentiate land types will vary according to the desired objectives, but any material difference in yield, or in practices necessary to maintain a desirable level of productivity will justify recognition of land types. The proposed procedure involves a more detailed study of the influence which soils, slope, erosion, and drainage have on specific crops …
