WATER: Focus on water research: Managed aquifer recharge

The Focus on water research series introduces you to the key cotton water researchers and their work. In this case study, Wendy Merritt from ANU outlines the investigation into the potential to implement Managed Aquifer Recharge (MAR) in the irrigated cotton growing regions of Australia, evaluating its feasibility across all facets (ie. financial, economic, technical, legislative, social and environmental).

NRM: Focus on NRM research: Managing the noogoora burr complex

The Focus on NRM research series introduces you to the key cotton NRM researchers and their work. In this case study, the teams from NSW Department of Primary Industries (NSW DPI), Murrumbidgee Irrigation and the University of Queensland talk about their research into the noogoora burr complex, under the Control Tools and Technologies for Established Pest Animals and Weeds program.

 

IRRIGATION: On-farm benefits of canopy temperature sensors - a grower perspective

Stewart Denston is an experienced cotton grower who has been trialling canopy temperature sensors (CTS) for the Macquarie Cotton Grower Association (CGA) since the 2014-15 season, including installing his own sensors in both heavier and lighter soils. The Denston’s have a family farming enterprise that is comprised of three separate farms.

An interview was conducted with Stewart Denston by Amanda Thomas, CottonInfo's Regional Extension Officer in the Macquarie Valley. Amanda has been facilitating the trial work with CTS in the valley for the past four seasons.

ENERGY: Integrating alternative energy solutions case study: Emerald, QLD

The case study, conducted by AgEcon/CottonInfo's Jon Welsh and AgEcon's Janine Powell, was undertaken to consider the economic and environmental impact of installing microgrids to offset the energy use of surface water irrigation pumps and a small grain drying facility in the Fitzroy Valley of Queensland. The study aims to find solutions ultimately leading to lower energy costs and greater sustainability through carbon emissions abatement. The study was supported by CRDC. 

NRM: Focus on NRM research: Keeping insect pests lower for longer

There are a range of ecosystem service benefits that flow from maintaining on-farm natural assets. Previous research has focused on the relationship of semi-natural vegetation providing individual ecosystem services, for example, biological control or pollination. However, there is little evidence to show the measurable effects of native vegetation on insect pest suppression in cotton production at a landscape scale or the mechanisms underpinning any effect.
