Ornamental Grower Perceptions of Wireless Irrigation Sensor Networks: Results from a National Survey

Abstract

<jats:p>Irrigation management systems that use wireless transmission of substrate moisture data are beginning to become commercially available for ornamental growers, particularly for use in soilless substrates. These systems allow growers to precisely monitor and control irrigation in real time and are being shown to save time and other resources. On-farm evaluations indicate that these systems have potential benefits extending beyond reductions in water use and associated irrigation inputs: Some growing systems experience increases in plant growth rates, with corresponding reductions in production time, whereas some experience reductions in disease pressure and corresponding plant losses. We asked ornamental growers across the nation what they see as potential benefits and limitations of these systems as a means of assessing the likely state of acceptance of this technology at the time of its initial introduction. Grower perceptions were overwhelmingly positive, with the majority of respondents agreeing that wireless sensor systems can increase irrigation efficiency, improve product quality, reduce product losses, reduce irrigation management costs, reduce disease prevalence, increase ability to manage growth, reduce irrigation management costs, and reduce monitoring costs. System cost and reliability were major concerns. Grower perceptions of the benefits and drawbacks of irrigation sensor networks varied across size and type of operation as well as geographically and by the type of water source used. Making wireless sensor systems affordable and robust will likely be critical determinants of the speed and reach of adoption of these technologies.</jats:p>

Diffusing Water Conservation and Treatment Technologies to Nursery and Greenhouse Growers

“…It is important that extension professionals help growers overcome barriers to adopting water conservation and treatment technologies (Hartstone, Knight, & Riley, 2006;Heaton, Barnhill, & Hill, 2012;Majsztrik et al, 2013) with water resources becoming more strained and water quality issues increasing (USEPA, 2013). However, the barriers to adoption are largely unknown due to a lack of research in this area.…”

Water Conserving Irrigation Practices, Plant Growth, Seasonal Crop Coefficients, and Nutrition of Container-Grown Woody Ornamentals

“…In a survey of nursery growers about the perceived benefits and limitations of wireless sensor networks, nearly half cited concerns that the systems may prove unreliable or not control irrigation correctly [29]. Likely, they worry that such complications would negatively impact plant growth and profitability.…”

Advancing Wireless Sensor Networks for Irrigation Management of Ornamental Crops: An Overview

“…Growers report overwhelmingly positive views of WSNs and look forward to increased irrigation efficiency, improved product quality, reduced product losses, reduced irrigation management costs, reduced disease prevalence, increased ability to manage growth, and reduced monitoring costs. System cost and reliability are major concerns, indicating that making WSNs affordable and robust will likely be critical determinants of the speed and breadth of adoption (Majsztrik et al, 2013a).…”
