25:
Efficient Nutrient and Water Use In Protected Culture

Objective(s):
What are the best methods for managing water and nutrients in protected culture? How can those measurements be made in real time and used for management making decisions? How do different substrates effect water and nutrient management these unique cultural systems? What are accurate budget estimates for nutrient management in these systems? These topics and more will be covered in the Efficient Nutrient and Water Use in Protected Culture workshop sponsored by the Plant Nutrient Management Working Group.
