While providing the proper soluble salts and pH levels are important in hydroponic systems, don’t overlook the significance of maintaining the optimum temperature, oxygen concentration and microbe level in the nutrient solution.

Maintaining the optimum temperature, oxygen and beneficial microbe levels are integral in hydroponic systems

Maintaining the proper soluble salts (electrical conductivity) level and pH are critical in hydroponic systems like nutrient film technique and floating rafts. While monitoring these properties are important, growers should not overlook the importance that temperature, oxygen level and microbial activity play in the growth of plants in these production systems.

“It’s not as much about maintaining root health as it is about managing the conditions in the rhizosphere, which is the region around the plant roots,” said Rosa Raudales, assistant professor of horticulture and greenhouse extension specialist at the University of Connecticut. “The area around the roots undergoes a lot of biological and chemical activity. Microorganisms in the rhizosphere feed on the exudate of the roots. Managing the rhizosphere and the conditions in the nutrient solution are critical to maintaining plant health.”

Food crops grown under cover gained the most in number of operations engaged in this production, an increase of 71 percent to 2,521. Although protected food crops did not account for the largest amount of sales, its $797 million in sales was the biggest increase (up 44 percent) from 2009 sales. Nursery stock, which accounted for $4.3 billion in sales was the top horticulture commodity, up 11 percent from 2009.

Family- or individually-owned businesses made up the largest number of operations, accounting for 53 percent. However, corporate-owned companies accounted for 76 percent of sales ($10.5 billion).

Total industry expenses were up 16 percent since 2009, with labor being the largest cost, accounting for 37 percent of total expenses in 2014.
