Changes to the cotton farming system over the last decade have caused a change in the weed spectrum, favouring glyphosate tolerant, smallseeded, biannual and perennial weeds.

Fleabane has become one of the most difficult-to-control weeds in dryland cropping systems in recent years, The weed problem is thought to have resulted from recent changes in farming practices toward greater use of z

Our research addresses three questionsI. Is soil biodiversity reduced in agricultural soil compared with undisturbed soilsΓ2. Does cropping affect which groups of fungi are present in agricultural soilsΓ3.

New South Wales water catchments are now having their third attempt at managing our natural resources each having come along with its own set of expectations This tells us that we may have the last chance to get Catch

Sorghum is extremely attractive to ovipositing heliothis (Hencoveipo armigero) moths.

Soil type and climate both influence the cotton plants response to soil moisture status. Soil types differ in both the amount of moisture contained and more importantly how this moisture is available to the plant.

In 1971 Dr HJ Firth wrote - 'the Murray- Darling system, in addition to being the greatest river Basin in the land, is one of the greatest and most complex problems of resource conservation and management.

Under limited water scenarios HydroLOGIC was able to optimise yield.- Irrigation application efficiencies were estimated to be near the industry average of 60 percent-Combining soil moisture probe information with Hyd

Previous studies of soil used for cotton production has highlighted that soil structural decline may be a potentially one of the limiting factor restricting cotton growth (CRDC report MCK IC & MCK 2C).

Deep drainage is essential for the removal of salts from the reach of crop root systems.

Submerged water plants (aquatic macrophytes) are a desirable component of shallow lakes and wetlands, and management activities should be directed to ensure their continual presence.

Knowledge is one of our most valuable and intangible assets.

Cotton production in Central Queensland will continue to impose a unique set of challenges due to climate and it’s remoteness from other production areas.

Purpose of Exchange: Attend Visual Basic Developers Conference, This application was for Scott Johnston to attend the Access/ Visual Basic Developers, Conference, Las Vegas, Nevada USA, 8-12 June 2003.

Fusarium wilt is considered by many growers, ginners, consultants and other industry personnel as the most important constraint to sustainable cotton production to have developed in recent years.

Scientific Exchange USA Scientist Dr Tom Sinclair (USDA/University of, Florida) to Narrabri, Following the International Crop Science Congress last year we were presented with a, unique opportunity to host internation

The current project was devised in the knowledge that increased sodicity and salinity of percolating water will alter the saturated conductivity of many soils, especially sodic soils.
