Vineyard Tech Advancements for Viticultural Decision-Making
Vineyard Tech Advancements for Viticultural Decision. Making Daniel Bosch
• Any sensors we use or data we collect should be part of a larger management decision making process. • Ideally we would use optimization models to improve and hasten decisions. • Data and models should reduce the complexity of the decision.
VSIM Model Lars Pierce lpierce@csumb. edu California State University, Monterey Bay Funding: CA Department of Water Resources
Modeling Irrigation Decisions VSIM Vineyard Soil-Irrigation Model • Automated Irrigation Scheduler • Forecasts Weekly Irrigation Needs • Evaluates Irrigation Schedules
VSIM Software System Automatically: Creates Farm Database Extracts By Block Vine Kc Soils Slope Aspect
Runs the VSIM Model Canopy Kc Model + Soil Water Budget Model
VSIM Calculates Daily: • • • Plant Water Use Soil Moisture Deep Drainage Leaf Water Potential Irrigation
Emails Summary Forecast to Grower
Emails Block Summaries to Grower
Emails Graphs to Grower
Benefits: VSIM uses farm shapefile to set up farm input database (easy set up for new farms). VSIM runs whenever VSIM server receives email with updated grower irrigation logs.
Benefits: VSIM irrigation forecasts are automatically generated and emailed to the grower. VSIM reports provide “early warning system” regarding vine growth and water stress.
Benefits: VSIM reports assist grower in maintaining target LWPs during wet and dry years. Helps grower to document efficient irrigation water use over growing season.
Initial VSIM Irrigation Trial Results (2014): • • • No significant differences in yield Water savings Improved juice color Earlier ripening Reduced Time Managing Irrigation
2015 Expand number of users & set up VSIM for use in other fruit/nut crops. Lars Pierce – lpierce@csumb. edu
Ideas to Enhance Irrigation Models Using Imagery • Higher Resolution Images to measure vine size versus cover crops • Precision farming • Heat Sensors to monitor vine stress • Greater Frequency of Images

Amount of Water to Apply
Needed Technology for Irrigation • Less expensive water meters • Less expensive soil moisture sensors
Farm Management Databases / Spreadsheets / Maps Budgets Monitor: Budget versus daily actuals Crop Estimation – random rows and vines Maps – work orders, precision farming Scheduling
Experimental Designs and Evaluation Simple Experimental Design setup and evaluation – inexpensive software Develop methods for quick evaluation, yield monitors, photo of bin, etc. Test and Retest
Drones Will imagery have zero cost or lower cost? Imagery is less important than the value of the data derived from imagery Will a drone be part of a management strategy or is it equipment?
Drones Size of drone will determine function Largest drones - Spraying, Seeding Smaller drones – imagery, place traps, survey for virus, broken emitters, count missing vines, monitor spray drift, collect data from ground sensors

And The Green Grass Grew All Around Well, the feather on the wing And the wing on the bird And the bird on the egg And the egg in the nest And the nest on the twig And the twig on the branch And the branch on the tree And the tree on the root And the root in the hole And the hole in the ground And the green grass grew all around, all around William Jerome, 1912
