At the Controlled Environment Agriculture Student Association, University of Arizona college students handle their very own pupil greenhouse, develop and promote crops — all with out the assist of soil, utilizing a way known as hydroponic farming.
What is hydroponics?
The club is described as “all things hydroponic” by CEASA president, Christopher Kaufmann, who’s a senior majoring in biosystems engineering. Hydroponics is a technique of farming the place vegetation are grown with out soil and changed by a water-based nutrient resolution.

This is a extra sustainable possibility than different agricultural strategies, because it eliminates the use of pesticides, makes use of much less water and may develop in much less house.
“Hydroponics uses up to 90% less water than soil-grown crops, so we can grow year-round,” Phil Braden, greenhouse supervisor of CEASA and a junior majoring in sustainable plant programs, stated. “A majority of our water usage actually goes to cooling the greenhouses, which is still substantially less than what it takes to water the crops in a field in Arizona.”
Selling produce at the Wildcat Country Market
This semester, CEASA is eager about the enterprise aspect of controlled environment agriculture, in keeping with CEASA Vice President Katie Klontz, who’s a senior majoring in agricultural know-how administration and training.
“We’re focusing on innovation within our greenhouse. So creating different systems, figuring out different types of produce than what you might traditionally see in a hydroponic greenhouse,” Klontz stated. “And then, we’re kind of developing a way to go through and start marketing and selling that produce in a farmer’s market.”
In the previous, they’ve bought their crops at the UA Agricultural Center’s Wildcat Country Market. Due to the coronavirus, they solely started promoting produce for half of the final tutorial 12 months, starting in February. This was as a result of CEASA actions being restricted with Zoom conferences and just one particular person initially being allowed in the greenhouse at a time, stated Kaufmann.
This fall semester, they haven’t but began promoting at the market, however goal to take action Oct. 22.

Outside of the greenhouse
Other than working in the greenhouse, CEASA members have had seminars, workshops and discipline journeys associated to controlled environment agriculture in the previous. This 12 months, some anticipated occasions are a tour of Biosphere 2, business excursions of bigger greenhouses and visitor audio system who’re engaged on the Mars Lunar Greenhouse.
CEASA presently meets as soon as per week on Fridays at 5 p.m. in Room 117 at the Controlled Environment Agriculture Center. For extra info, take a look at their web site, Instagram or Facebook.
