The Efficient Vineyard team will be presenting a webinar the second Tuesday of each month at 1:00PM (Eastern Time – US and Canada)

Our next webinar: Tuesday May 14, 2019 by Dr James Taylor of the Spatial Data Technology group

Webinar 10:

This webinar will provide background and scope for the rest of the webinar series as well as straight-talk on how applying Precision viticulture (PV) can take the guess work out of vineyard management and how a short-term investment in PV can increase profitability, efficiency, and sustainability.

Soil is the growing medium for grapevines, playing a key role in nutrient and water availability and cycling. Cultural practices like irrigation, fertilization, liming and cover cropping must be adapted to a specific soil environment. We will discuss how inherent variability in soil properties can be measured spatially using off-the-shelf sensors and how "work smarter, not harder" translates to soil sampling.

An efficient grapevine canopy maximizes photosynthetic capacity while minimizing internal shading. Efficient photosynthesis drives fruit production and quality. This webinar covers the basics of canopy architecture and how sensors collect NDVI data (don't worry, we will break that down too) that can be used to map canopy size in vineyards.

For the average grower, grape yield is measured in bin trailers, gondolas or truck loads. Total yield is usually a reflection of truck load weigh slips for fruit in the table, raisin or juice market or records kept on the press deck at the winery. Commercially available yield monitors have been adapted to grape harvesters and make it possible to measure yield in real time as a harvester moves down the row. We will talk about how these monitors work and how yield data can be mapped in real time and post-harvest.

This webinar will discuss our work on the measuring various viticultural parameters in the field using cameras and artificial intelligence. We will describe the hardware used to collect images in the field, the software pipeline that extracts measurements from the camera images, the results of using this approach to measure parameters in the field, and some of the challenges and opportunities we see for this line of work going forward. George Kantor of Carnegie Mellon will be a guest speaker.

We have learned about the various ways to collect spatial vineyard data on soil, canopy and crop. This webinar will follow this valuable information on its journey from the sensor through processing and mapping software and back to the vineyard for variable rate management.

This webinar presents the Efficient Vineyard protocol for estimating shoot number across entire vineyards and using variable rate technology to balance shoot number with vine size according to our crop load model.


Webinar 8: Spatial Data Used in Practical Applications

From simple maps generated from one data layer for vineyard scouting to fully-integrated spatial-data-driven variable-rate mechanized applications, the usefulness of spatial information is starting to take hold in our vineyard operations. Terry Bates, Kevin Martin, and Tim Weigle discuss how spatial data are being used for practical vineyard applications.


Webinar 9: Sensors and Sampling - or why do I still need to visit my vineyard when I have all this kit!

Editor's note: there is a bit of a hiccup in the recording due to an internet disconnect. We picked back up as soon as possible but some of the recording was lost.

The previous webinars have looked at a variety of sensing technologies and putting the information from these technologies to use for management. Commercially available sensors give some great information, but it is not always the complete picture. We still need to spend time in vineyards to validate the data; however, having the sensor information should make our time in the vineyard more efficient and more effective. In this webinar, we will look more broadly at what sensors can and cannot give us, what we should expect and what you need to do to get the best information out of them.
