Description of study
What?
Runoff, sediment and pesticide samples were collected for wheat cotton and conventional fields.
When and Where?
The NSW field site was based at Darling Farms, Bourke.
How?
Paddock scale (25ha) monitoring of sediment, nutrient and pesticide movement from rainfall and irrigation runoff, was carried out on a typical irrigated cotton farm. Two stage rectangular weirs were fitted at the tail drain outlet of the field. Runoff depth was continuously logged at 2 minute intervals using ultrasonic transducers attached to monitor sensor data loggers. Sediment, nutrient and pesticide samples were collected on a flow weighted basis using Issco pumping samplers. Runoff, sediment, nutrient and pesticides were monitored all year round and additional hand sampling was carried out during storm events. Rainfall was monitored using a monitor sensor pluviometer and data logger at 1 minute intervals. Detailed records of farming practices, irrigation practices, crop growth and entomology were recorded throughout the season.
