Soil-Saving Schools
Journal of the Department of Agriculture, Western Australia, Series 3
Save the soil for your sons and grandsons," or "Every farmer his own soil conservationist" might well serve as slogans for the recently-inaugurated farmers' schools organised in this State by the Soil Conservation Service. Judging by the enthusiasm shown by pupils at the first two schools, held in August last, this highly practical approach to an important subject seems destined to usher in an entirely new conception of soil conservation work as it affects the individual land-owner.
Sunrise And Sunset Tables
Journal of the Department of Agriculture, Western Australia, Series 3
Times of sunrise and sunset for every fifth day, are given for a number of towns throughout the State. Times for a town not on the list may be estimated if its position in relation to one or more of the listed towns is known. The times given for sunrise are those of the first appearance of the top edge of the sun over a true horizon; those for sunset give the time of the sun's disappearance below a true horizon. Situation in a valley would make the sun appear to rise later, and on a hill it would appear …
The Hose U-Tube Level, J P. Fallon
The Hose U-Tube Level, J P. Fallon
Journal of the Department of Agriculture, Western Australia, Series 3
With the growing use of soil conservation practices throughout the farming areas, there has been an increasing demand for a simple levelling device that will enable farmers to take their own levels. When they have become familiar with the use of pasture furrows, contour banks and the various other mechanical erosion control measures, farmers with the aid of such an instrument would be able to make an immediate start on an erosion control programme. The instrument would also prove useful for numerous small jobs around the farm when accurate levels are required. Tests have shown the "Hose U-Tube Level" here …
Soil Conservation Farming
Journal of the Department of Agriculture, Western Australia, Series 3
A list of farmers known to be using contour practices for soil conservation, is printed at the end of this note. It will enable other interested farmers to find and see something of such methods. Now is considered an appropriate time to publish this list as many farmers will shortly be travelling through the countryside to agricultural shows and field days.

Dams On The Hillsides
Journal of the Department of Agriculture, Western Australia, Series 3
A reader of the "Journal of Agriculture" recently wrote to the Commissioner of Soil Conservation concerning the current tendency towards sinking dams on hillsides. He stated that many farmers and contractors were throwing up holding banks in such a manner that a large percentage of the water impounded was lost by seepage under the banks.
Water Erosion Control, L C. Lightfoot
Water Erosion Control, L C. Lightfoot
Journal of the Department of Agriculture, Western Australia, Series 3
Although soil erosion caused by water action is common in our agricultural areas, effective erosion control measures, likely to pay for themselves quickly, can be applied in nearly every case. Plant cover above the soil surface, and fertile soil with good structures are the main factors which enable soils to resist erosion. Dense pasture gives the best cover and at the same time improves the fertility and structure of the soil both effectively and economically, so land management adjusted to the need and capability of soils, slopes and climate is of first importance. Contour practices are of secondary value and …

Kimberley Soils Need Phosphates, W. M. Nunn
Kimberley Soils Need Phosphates, W. M. Nunn
Journal of the Department of Agriculture, Western Australia, Series 3
Research work carried out at the Kimberley Research Station on the Ord River, and on experimental plots throughout the East and West Kimberleys, indicates that the soils of the Kimberleys are quite as deficient in phosphorus as are the soils of our agricultural areas where superphosphate is essential to the growth of most crops.
This may come as a surprise to many people, for there has been a widespread tendency to assume that the Kimberleys soils, especially those of the Ord and Fitzroy valleys, are highly fertile.
The black earths of Queensland's Darling Downs produce most enviable yields of sorghum …

Soil Conservation In Western Australia, G. H. Burvill
Soil Conservation In Western Australia, G. H. Burvill
Journal of the Department of Agriculture, Western Australia, Series 3
Soil is a farmer's basic asset. This issue of "The Journal of Agriculture" in a new form designed to provide still better service to the farming community, is an appropriate medium through which to remind the man on the land of what the soil means to him—and to the State. The farmer's duties to himself, his family and the State are summed up in the words "soil conservation" which is merely another way of saying "wise land use."
