The research included a survey to identify costs and benefits to the growers, and to learn if any are using their systems to reduce drainage problems. While results indicated that none of the growers relied on their systems specifically to manage drainage problems, they were in general agreement that the system provides water savings, increased seed germination and higher yields, reduced cultural costs, and reduced run-off. High start-up cost was seen as the main disadvantage of the system, growers reported. Overall results of the survey indicate that most of the growers who continue to use linear move systems perceive some economic benefit, Zoldoske said. Coupling that advantage with drainage control ability makes linear move systems an attractive option where runoff is a problem.
Further investigation is warranted.
