Trees For Windbreaks On Swan Coastal Plain Farms, Leon English, Ken Angell, Metropolitan District Office, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Strong easterly and south-westerly winds are a feature of the Swan Coastal Plain and we receive frequent inquiries about which tree species are suitable for planting as windbreaks. When selecting trees for windbreaks you must match the species to the various soil types which occur along the Coastal Plain. The mature height of the tree is also an important consideration in good windbreak design. This Bulletin lists species which are suitable for windbreaks in descending order of mature height and indicates the soil type(s) on which they should be planted.

The Soils Of The Salmon Gums District, Western Australia, George Henry Burvill

Technical Bulletins

Most of the soils are grey and brown solonized soils. The subsoils, to about 2 m, are calcareous sandy clays with limestone rubble, but there are three main surface variations: sandy surfaced, 5-30 cm deep, passing abruptly to the sandy clay subsoil with lime nodules. The Circle Valley sand and Scaddan sand are major types. Scaddan sand has a domed subsoil clay. Powdery calcareous sandy loam; and clay loam and clay with some lime in the subsoil, but less than in 1 and 2.

Safe Disposal Of Pesticide Containers And Residue, Doug Johnson, Monroe Rasnake, James Martin

Soil Science News and Views

The use of pesticides (herbicides, insecticides, fungicides, etc.) has been an important factor in improving productivity of American agriculture to the point that quantity and quality of food and fiber produced by American farmers is unequalled in the world. However, in recent years, increased concern is being expressed regarding potential harmful effects of pesticide use on the environment. Most farmers want to know how to safely handle pesticides and dispose of waste materials, and the pesticide industry is working hard to develop better systems for handling pesticides. However, poor disposal practices are still too common.

How Much Fertilizer Ls Needed For Corn?, Kenneth L. Wells, Keenan Turner

Soil Science News and Views

Corn producers are faced each year with the decision of how much money to invest in fertilizer for use on their crop. Differing philosophies used by those who make fertilizer recommendations often leave the grower bewildered as to what is best to do. It is not unusual for a producer to be told by his agricultural extension agent that he doesn't need any phosphate and potash on fields which test high in these nutrients while other sources may recommend fertilizer use. The philosophy behind the zero P-K recommendation made by extension agents in such cases is based on University of …

The Real Value Of Agricultural Limestone, Monroe Rasnake

Soil Science News and Views

There are big differences in quality of agricultural lime sold in Kentucky. According to the most recent test results, the Relative Neutralizing Value (RNV) of Kentucky aglime ranged from a low of 50 to a high of 89. Actually, some were below the RNV of 50, but these did not meet state lime law regulations and could not legally be sold as ground agricultural limestone.

Contending With Soil Compaction, Kenneth L. Wells, Lloyd W. Murdock

Soil Science News and Views

Most compaction results from use of machinery on soil which is too wet to work well, or from overworking soil and destroying natural structure. The resultant pressure from tires and tillage tools compresses more soil into a given volume. Regardless of reason, the proportion of solid soil material relative to total volume of soil increases. In the process, natural soil aggregates are broken down and large pores become smaller, generally resulting in soil more difficult for plant roots to penetrate.

Potential Of Surface Water Contamination From Three Triazine Herbicides, William W. Witt, Kip W. Sander

KWRRI Research Reports

The movement of atrazine, cyanazine, and simazine from the site of application was monitored under conventional, reduced, and no-tillage conditions. Less water and soil was lost from the no-tillage and reduced tillage conditions. Conventional tillage conditions had about 66,000 L/ha runoff in 1986-87 and about 123,000 L/ha runoff in 1987-88. Seasonal rainfall was 885 mm in 1986-87 and 397 mm in 1987-88. The rainfall intensity was greater during the first two events in 1987 than the corresponding events in 1986. The first rainfall event in 1986 accounted for 91, 89, and 78% of the total seasonal loss of atrazine, cyanazine, …

Carlton Plains Soil Survey In The Shire Of Wyndham, East Kimberley, T C. Stoneman

Resource management technical reports

The Carlton Plains covers approximately 11,750 ha midway between Wyndham and Kununurra on the northern bank of the Ord River in the Shire of East Kimberley. The survey area is divided into two geomorphic units, the clay plains and the levee areas. Soils of the former generally belong to the Cununurra family of cracking clays while those of the levees are generally more variable and of medium texture.Samples of the major soils were collected for mechanical analysis and basic chemical analysis.Sodium chloride percentages and exchangeable sodium percentages are both high on the clay soils of the western plain. The suitability …

Canola: A New Cash Crop For Kentucky, James H. Herbek, Lloyd W. Murdock, Dan Kirkland, T. Gray

Soil Science News and Views

For the past few years, Kentucky farmers have become more interested in "alternative" cash crops for their farming operations. One such crop that is starting to receive attention is Canola. Classified as an oil crop, Canola is a type of oilseed rape. Rape is a member of the mustard family and is closely related to turnip. cabbage, cauliflower, broccoli and mustards. It is a cool-season annual and an important oilseed crop in many parts of the world that is used for both human consumption and industrial purposes. Major rapeseed production areas are in Europe and Canada. The seed contains approximately …
