Small palaeochannels located in irrigated cotton fields have been identified as areas of potential high deep drainage (Triantafilis et al. 2003).

The project will investigate the impact of land management practices (tillage, stubble management, crop rotation) on carbon losses through terrestrial pathways such as runoff, erosion, and leaching.

Aim and objectives On average about one third of applied nitrogen is lost which costs the cotton industry $32 million each year.

Australian cotton is now dominated by transgenic (Bt) varieties, which provides a strong platform for Integrated Pest Management (IPM) of key pests such as Helicoverpa spp.

With rogue cotton becoming a seemingly common sight along roadways and drainage lines a survey was conducted throughout Queensland and parts of northern New South Wales covering over 13,000km of roads and drainage way

The Australian cotton industry has used values of Gross Production Water Use Index (GPWUIfarm) to benchmark water use efficiency since 1988/89.

Micronaire is a measure of fibre linear density (fineness) and maturity. Factors affecting supply and partitioning of photosynthetic assimilates to fruit affect micronaire.

The frequency and severity of potassium (K) deficiency symptoms in cotton on the highly productive clay soils in Texas have increased in recent years.

Early planting poses some risk in cool regions resulting in re-planting if cold days or frost occur after emergence.

Careful management is needed if row crops are to be established after rice crops. It will take about 18 months for the soil to be suitable for row crops after the conversion of rice layouts to a row crop layout.

One of the key challenges growers have when they have water for a limited number of irrigations is confidently knowing when to use this water to optimise yield, quality and water use efficiency.

Solenopsis mealybug (Phenococcus solenopsis) has been a pest of cotton in Australia since initial outbreaks in Emerald and the Burdekin in 2009.

Question/issue being addressed? Continued pressure on oil price affects cotton production because it is a highly mechanised and high-input crop that relies heavily on diesel, fertilisers, chemicals and water.

Transform insecticide is a new insecticide which was registered for control of the key sap-feeding pests in Australian cotton in 2013.

Why are disease surveys important? Surveys are conducted by pathologists to monitor the distribution and importance of key endemic pests and record the presence or absence of new or exotic diseases.

The Problem Cotton aphid and silverleaf whitefly feed on phloem sap and produce sugar rich honeydew that can contaminate open cotton bolls leading to downstream problems with processing.

The cotton industry is challenged with attracting and retaining core staff, on-farm labour, and access to professional advisers and service providers.

Outline Silverleaf Whitefly (Bemisia tabaci) is a major pest of cotton. This is because it produces sticky honeydew that contaminates lint, reducing the quality of cotton.

Deep drainage below irrigated crops wastes a scarce resource and can potentially lead to rising water tables and salinity.

challenges suggest the need for research with cotton growers, distributers and participants in the production cycle, to understand what people think the future holds for the industry, and it's cotton communities.
