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.

Phalaris Staggers : Prevention By Cobalt Bullets, Bryan J. Gorddard, P. P. Mann, A. J. Hadlow
Journal of the Department of Agriculture, Western Australia, Series 4
FARMERS in the south west of Western Australia are familiar with the use of cobalt for the prevention of ill-thrift and deaths due to cobalt deficiency in sheep and cattle.
Less common is the use of cobalt for the prevention of chronic phalaris poisoning, known as phalaris staggers.
This condition is well known in eastern Australia, but only isolated cases have been recorded in W.A. no doubt due to the relatively small area sown to phalaris in this state.
Egg Shell Quality, R J. Bishop
Egg Shell Quality, R J. Bishop
Journal of the Department of Agriculture, Western Australia, Series 4
Recent overseas work and local industry developments indicate that the calcium content of feed for laying hens in Western Australia should be increased to achieve satisfactory egg shell strength.
Age, temperature and breeding are other important influences on egg shell quality.

Some Results With Nitrogen Fertiliser On Cereals At Esperance Plain Research Station, William John Toms
Journal of the Department of Agriculture, Western Australia, Series 4
ON newly-cleared land at Esperance Plain Research Station the use of sulphate of ammonia on cereals has proved profitable over a number of seasons.
The response to sulphate of ammonia varies markedly with the season.
