Clogging of irrigation systems is a persistent and expensive problem in greenhouses and nurseries because it causes uneven irrigation and consequently crop loss. In this project, we aim to identify algae that accumulates in irrigation systems—causing clogging— and then evaluate chemical and non-chemical alternatives to prevent or reduce algae accumulation on irrigation systems. We expect that growers who are able to reduce clogging of the irrigation systems will directly benefit through savings in labor associated with inspecting, cleaning, and replacing clogged emitters. In this first stage of our project, we conducted preliminary sampling and then validated a series of protocols that will help us study algae in irrigation systems. We have recruited six operations that will allow us to continually sample.
The objectives of this project are to:
On this first stage of the project, we have conducted the following activities:
While our project has made timely progress in the first six months, we still have not generated new or conclusive information that can be disseminated to growers.
Not applicable at this stage of the project.
None yet.
In the following presentations, we included a slide that mentioned the direction of this project, HRI sponsorship, and the need to get grower participants.
The industry still needs to know what are the environmental conditions (biological or irrigation systems design) that they can manipulate to prevent algae accumulation on irrigation systems and other surfaces.
The Horticultural Research Institute (HRI), the AmericanHort foundation, has provided more than $9.5 million in funds to research projects covering a broad range of production, environmental, and business issues important to the green industry. Nearly $18 million is committed to the endowment by individuals, corporations, and associations .
