Research Project: Examining Nutrient Retention and Leaching Potential of Alternative Soiless Substrates Used for Container-Grown Crops

Location: Southern Horticultural Research

Project Number: 6062-21430-002-04
Project Type: Specific Cooperative Agreement

Start Date: Sep 01, 2012
End Date: Aug 31, 2017

Objective:
The objective of this cooperative research is to characterize and fully measure the retention and leaching potential of certain nutrients in various soilless substrates used for container-grown crops.

Approach:
Using the cooperator's existing nutrient recovery system, nutrients (from various sources) will be applied to plants grown in various alternative soilless container substrates. The effluent and/or substrate at various depths will be collected and analyzed to determine the rate of nutrient retention and leaching.
