Soil And Plant Analysis : A Guide To Fertilizer Usage, Walter Jacob Cox
Soil And Plant Analysis : A Guide To Fertilizer Usage, Walter Jacob Cox
Journal of the Department of Agriculture, Western Australia, Series 4
Soil and plant analysis can be used to identify problems in soils, diagnose nutrient deficiencies and as a guide to fertiliser usage.
Soil testing is particularily useful where large amounts of phosphorus and potassium are leached or removed from the paddock in hay or silage.
Actual rates of fertiliser can only be recommended from soil testing and only in conjunction with additional biological and economic information.
Producing 20-Month Old Beef Steers Off Annual Pasture, K D. Greathead, D. J. Barker, W. J. Ryan
Producing 20-Month Old Beef Steers Off Annual Pasture, K D. Greathead, D. J. Barker, W. J. Ryan
Journal of the Department of Agriculture, Western Australia, Series 4
A recent Mt Barker experiment compared two systems of fodder conservation with continuous grazing, using two types of steers, at three stocking rates. Year-round performance, carcass composition, and resulting costs and returns per hectare were assessed.
Production per hectare was greatest from crossbred steers at the intermediate stocking rate with either type of fodder conservation.
New Header Treatment Aids Weevil Control, J H. Moulden
New Header Treatment Aids Weevil Control, J H. Moulden
Journal of the Department of Agriculture, Western Australia, Series 4
A new insecticide formulation supplied in high pressure cylinders simplifies weevil control in headers.
Potassium Deficiency In Lupins : Identification, Rates, Times And Method Of Application, Walter Jacob Cox
Potassium Deficiency In Lupins : Identification, Rates, Times And Method Of Application, Walter Jacob Cox
Journal of the Department of Agriculture, Western Australia, Series 4
Large areas of sandplain soils north of Perth are low in potassium levels, and responses to applied potassium have been large for both sub. clover and grain lupins.
This article indicates where potassium might be needed, and how to diagnose and overcome deficiencies in lupins.
Deep Drainage As A Method Of Treating Saltland, Eric Bettenay
Deep Drainage As A Method Of Treating Saltland, Eric Bettenay
Journal of the Department of Agriculture, Western Australia, Series 4
In some situations, deep drainage may be warranted to return salt-affected land to full production.
This method is being investigated at CSIRO's Yalanbee Experiment Station.
Water Movement Through Soil, R A. Nulsen
Water Movement Through Soil, R A. Nulsen
Journal of the Department of Agriculture, Western Australia, Series 4
Even a good quality stock water moving to the surface can cause a salinity problem in only a few years.
Landform, Natural Drainage And Salinity, Eric Bettenay
Landform, Natural Drainage And Salinity, Eric Bettenay
Journal of the Department of Agriculture, Western Australia, Series 4
An understanding of salt movement in streams and groundwater may lead to better methods of control and prevention of salinity.
Effects Of Surface Drainage On Dryland Salinity, P R. George, T. R. Negus
Effects Of Surface Drainage On Dryland Salinity, P R. George, T. R. Negus
Journal of the Department of Agriculture, Western Australia, Series 4
Areas which are salt-affected are often also flooded. Although flooding is not the basic cause of salinity, surface drainage may improve conditions for plant growth, and this article describes suitable methods
Western Australian Soils Store Large Quantities Of Salt, C V. Malcolm, R. A. Nulsen, C. Henschke
Western Australian Soils Store Large Quantities Of Salt, C V. Malcolm, R. A. Nulsen, C. Henschke
Journal of the Department of Agriculture, Western Australia, Series 4
Enormous quantities of salt are stored in the soil in the agricultural areas of Western Australia. Small movements in this salt can produce large effects on farms.
The Dryland Salinity Problem In North America, P R. George
The Dryland Salinity Problem In North America, P R. George
Journal of the Department of Agriculture, Western Australia, Series 4
North america also has a dryland salinity problem although the source is different.
Plants As Pumps, E A N Greenwood
Plants As Pumps, E A N Greenwood
Journal of the Department of Agriculture, Western Australia, Series 4
Native species vary greatly in their ability to pump ground water.
CSIRO studies are measuring water use by different plants to plan revegetation strategies.
Soil Salinity In Western Australia : A Summary, T C. Stoneman
Soil Salinity In Western Australia : A Summary, T C. Stoneman
Journal of the Department of Agriculture, Western Australia, Series 4
Soil salinity problems have long been recognised in Western Australia. The earliest published explanation in 1924 suggested that removing native vegetation increased stream salinity, and this basic cause has been confirmed by many studies since.
