Progress In The Control Of Cotton Fireweed, Geoffrey A. Pearce

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

Cotton Fireweed (Erechtites quadridentata) is native to Western Australia and was first collected by Drummond before 1850. In its natural habitat it is quite insignificant and passes unnoticed.

Cotton fireweed, a native perennial plant, has become a serious weed in the south coastal districts and is now one of the most widespread weeds in the State.

Land Preparation For Border Irrigation, B Swan

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

LARGE amounts of water may be lost through excess run-off and deep percolation.

Proper preparation of irrigation land can help to minimise these losses.

This preparation is done by grading or levelling so that the original ground surface is shaped to allow for a more uniform distribution of water.

Profitable Returns From Saltland, C V. Malcolm

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

The recent saltland survey disclosed that about 305,000 acres of land previously cleared and sown had become salt affected.

This represents a serious loss in production but is offset by the fact that much of the land is capable of producing high yields of good quality fodder.

Farm Dams In The Wheatbelt, J E. Watson

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

MANY new farm dams are sunk each year in the wheatbelt and much money is spent on them.

With continued development of new land, and increasing stock carrying capacity of older land under legume pastures, the need for more water supplies will continue for a long time.
