CCROP-Container Crop Resource
Optimization Program

CCROP
Web-based tool that assists with
decisions about container plant production
When should I space my
containers?
How much irrigation
water should I apply
today?
How much water can I
save with an
ET-based irrigation
schedule?
How much runoff can I
expect?
When will my crop be
marketable?
How much nitrogen is in
my runoff?
Container Production Decision Tool
Nursery production is an input and output process
integrated with complex biology and physical phenomena
Decisions are made about inputs that impact outputs
Managers do the integrations based on experience
What if ????
CCROP
Inputs by user:
Weather, mgt. parameters
Irrigation – fixed or ET
Fertilization – CRF
Computer models do production
simulations based on inputs
Outputs interpreted by user:
Date of market or size
Runoff volume
Runoff nutrient amount
Assumptions
A. Uniform Irrigation
B. Uniform Spacing
C. Uniform Plants
D. No Pest Damage
E. Good Quality Liners
Quantify the Biological
and Physical Phenomena
