Container Nursery Irrigation Evaluation Practices

Irrigation is the largest consumer of water worldwide, which in turn consumes large amounts of energy. In Georgia, the industrial sector, which includes agriculture, is the second largest energy using sector. Container nursery production is included in this sector and is rapidly growing in United States agriculture. High irrigation inputs and investments in equipment, fuel, maintenance and labor are required to increase net income in nursery production. Irrigation type, design, and efficiency are critical in water conservation. The objectives of this study are to evaluate irrigation equipment, practices, and efficiency at a large container nursery in Georgia. Pumping plant evaluations will be conducted to determine pumping efficiency and water delivery efficiency. Equipment will be metered and monitored and data will be evaluated to determine problem areas. BMP's and tools will be recommended for irrigation efficiency and water conservation. Impact Statement Irrigation water is an invaluable resource which will be conserved by using tools such as efficient pumping practices, equipment monitoring, and data collection. This in turn will reduce runoff and minimize nutrient and pesticide leaching which will improve water quality and quantity. Energy in the form of electricity will be conserved with efficient irrigation practices.
