Urea For Sheep And Cattle On Dry Feed, Laurence C. Snook

Journal of the Department of Agriculture, Western Australia, Series 4

Urea can be a valuable supplement for ruminants which have to depend on dry feed low in protein.

Urea is extremely poisonous if eaten in excess and great care must be taken when feeding it to stock.

There are a variety of ways in which urea can be fed and these are outlined in this article.

Root Diseases In Wheat On Clover Ley : Factors Under Investigation. 1. The Role Of Oats After Ley, S C. Chambers

Journal of the Department of Agriculture, Western Australia, Series 4

The role of oats in relation to root diseases of wheat was examined at four of the State Wheat Research Stations.

Several recognised pathogenic organisms were isolated in the course of the investigation, the most important being Ophiobolus graminis, which is the cause of "take-all."

Results suggest that one year under oats after clover ley is sufficient to reduce the incidence of take-all, except when seasonal conditions are extremely favourable to the disease.

In areas where take-all is a problem, wheat planted after a first crop of oats can sometimes give a higher yield than a first crop of wheat. …
