Research Project: Optimizing Mineral Nutrition in Container-Grown Crops in Soilless Substrates

Location: Horticultural Crops Production and Genetic Improvement Research Unit

Project Number: 2072-21000-055-028-G
Project Type: Grant

Start Date: Sep 1, 2021
End Date: Oct 31, 2022

Objective:
Characterize impact of irrigation and nutrition on crop quality and nutrient leaching.

Approach:
The effects of different cultural practices (fertilizer and irrigation management) will be investigated in a series of experiments with perennial nursery crops. Using different nursery crop species, we will assess how (1) digital imagery can be used to monitor crop performance (nutrition and water stress); and (2) fertilizer rate alters plant nutrient uptake and nutrient run-off into the environment. Experiments will be performed on a run-off pad, a unique system that enables the collection of run-off from container-grown crops.
