Dry Season In The Eastern And North-Eastern Wheatbelt, George Henry Burvill
Dry Season In The Eastern And North-Eastern Wheatbelt, George Henry Burvill
Journal of the Department of Agriculture, Western Australia, Series 4
The drought of 1969 ended an 11-year run of good seasons in the eastern and north-eastern wheatbelt. Good years usually have above average rainfall; wheat yields and pasture growth are greatly reduced if rains are well below average. Eighty years records show that half the years must be expected to be below average and about one-third could be well below. This area produces one-third of the State's wheat and has 9 per cent, of its sheep.
Superphosphate Deficiency Raises Pasture Oestrogens, H G. Neil, T. Marshall
Superphosphate Deficiency Raises Pasture Oestrogens, H G. Neil, T. Marshall
Journal of the Department of Agriculture, Western Australia, Series 4
A recent field experiment on established pastures at Esperance Downs Research Station has demonstrated a relationship between superphosphate application, pasture oestrogens and oestrogenic response in sheep.
Results of the experiment indicate that on phosphate deficient soils carrying oestrogenic clovers, the levels of oestrogenic materials in the pasture are increased if superphosphate applications are below those recommended for healthy pasture growth.
Copper Requirements For The South-Eastern Wheatbelt, D J. Gilbey, K. D. Greathead, J. W. Gartrell
Copper Requirements For The South-Eastern Wheatbelt, D J. Gilbey, K. D. Greathead, J. W. Gartrell
Journal of the Department of Agriculture, Western Australia, Series 4
FARM experience and the results of five years intensive research have shown copper deficiency to be widespread in the south-eastern wheatbelt.
On many areas of the south-eastern wheatbelt, copper deficiency is likely to restrict wheat yields.
Likelihood Of Drought Years In South-Western Australia : How Often Can Droughts Such As That Of 1969 Be Expected In Western Australia's Farming Areas?, Eugene Adsil Fitzpatrick
Likelihood Of Drought Years In South-Western Australia : How Often Can Droughts Such As That Of 1969 Be Expected In Western Australia's Farming Areas?, Eugene Adsil Fitzpatrick
Journal of the Department of Agriculture, Western Australia, Series 4
Because of the serious consequences of drought to individual farmers and to Western Australia's economy, it is worth making an early appraisal of the 1969 rainfall conditions that led to the State's most recent drought in an attempt to estimate how often such seasons might be expected in the agricultural areas.
