Vineyard Nutrition Survey

A message from Gabriel Torres:

Vineyard Nutrition Survey

A multi-institutional research team involved in the HiRes Vineyard Nutrient Management Project seeks to understand current vineyard practices and the technologies that may be used for improving nutrient management practices. They invite all commercial grape growers, consultants, and vineyard management companies from the wine, table, raisin, and juice grape industries across the US to complete a survey. The survey will gather input on what, how, and why nutrient practices are used in vineyards. Make sure your state and grape sector are represented--participate today!


To complete the survey, go to https://beav.es/JRk.


If you have any questions about the survey or the research, please contact

Patty Skinkis, Oregon State University, or

Markus Keller, Washington State University.

Vit Tips Survey - June 2020

Vit Tips Survey:

Dr. Elisabeth Forrestel and her team from UC Davis are studying water management during heat wave and hope to find the best strategy on irrigation during heat event to improve yield and fruit quality of grape. Heat events are usual for San Joaquin Valley area during summer. She hopes to get some feed back from growers on some key issues, like water.

As part of this work, we’ve developed a general survey to better understand the types of irrigation practices growers currently use in response to heat extremes. This will help inform how we frame future research questions around the potential effects of our experiments on irrigation. We recognize that the survey questions and response options are painted with very broad brush strokes and that the realities of grower decision making around irrigation are more nuanced, and want to stress that this survey is meant to provide a 30,000 foot view. 

In order to ensure that our survey is representative of a wide cross-section of growers and operations across the state, we are reaching out to ask for your participation in the survey as a viticulture professional and to ask that you forward the survey link to your networks of growers, vineyard managers, consultants, advisors, and other viticulture professionals.

The survey should only take about 10 minutes to complete. It is anonymous and all individual responses will be kept confidential, though we may share the aggregated results in presentations or publications.


The survey can be found here: shorturl.at/ainU4
