Sustainable Winegrowing ·

2022/04/07

The Efficient Vineyard Project uses three phases to help growers improve their farming techniques; Measure, Model, and Manage. Terry Bates, Senior Research Associate at Cornell University in the School of Integrative Plant Sciences and Director of the Cornell Lake Erie Research and Extension Laboratory, has worked with the Efficient Vineyard Project since 2015 to collect and interoperate spatial data. He knew that growers were aware that variation in the vineyard was important to manage, but they

Dr. Tarah Sullivan is Assistant Professor of Soil Microbiology at Washington State University. In this interview, Tarah discusses how the plant microbiome mirrors the human gut, the ways in which soil microorganisms can alter the bioavailability of micronutrients and metals for plants, why plants in alkaline soils can be deficient in iron when the soil is not, if cover crops can improve soil microbial communities, and what is next for her research. Tarah’s research emphasis is on linking the

2022/02/17

Greg Pennyroyal of Wilson Creek Winery and Vineyards was looking for soil moisture systems and found that the products available in the market were all expensive, proprietary systems that did not meet the needs of small block Temecula vineyards. He partnered with Reinier van der Lee, CEO of Vinduino, to reverse engineer the technology to develop a product that would give the same results for a fraction of the cost. They have expanded this project over the last five years to collect more and more

2022/02/03

There are numerous tools and technologies to improve irrigation efficiency but by looking at grower demographics, we can better predict which growers will implement best management practices. Plus, we can learn how to educate all growers to improve adoption. Nicholas Babin, Assistant Professor of Natural Resources Management and Environmental Sciences at California Polytechnic State University, conducted a two-year study to assess Paso Robles California AVA grape growers’ thoughts around climate

2022/01/20

While many growers are familiar with the Western Leafhopper, they may not know as much about the Virginia Creeper Leafhopper. Houston Wilson, Assistant Cooperative Extension Specialist in the Department of Entomology at UC Riverside and Director of UC Organic Agriculture Institute has been studying the Virginia Creeper Leafhopper and potential biological controls. Leafhoppers are pierce and suck feeders. The insect removes small amounts of plant material causing a stippling effect on the leaf. This

Consumer demand for transparency and sustainability of their food system is leading to more and more agrochemical restrictions to address concerns for pollinators, noenicitinoids, and drift. Additionally, ESG (Environmental, Social, and Governance) investors are putting pressure on the chemical industry to improve their metrics. Pam Marrone, Founder and CEO of Marrone Bio Innovations outlines the market, status, and potential for biologicals in this excerpt from our 2020 Sustainable Ag Expo

2021/12/16

Maintaining agricultural land can be a solution to climate change. Renata Brillinger, Executive Director at California Climate & Agriculture Network (CalCAN), and her team are working to incentivize sustainable practices like composting, cover crops, and solar pumps at farms. They promote four grant programs that help farmers and ranchers have a positive impact on the planet and their bottom line. The first is to prevent urban sprawl by funding easements to maintain working farmland. The second is

2021/12/02

David R. Montgomery defines regenerative agriculture as leaving the land better off and more fertile as a consequence of cultivation. David studied geology at Stanford University before earning his Ph.D. in geomorphology at UC Berkeley. Today he teaches at the University of Washington where he studies the evolution of topography and how geological processes shape landscapes and influence ecological systems. In this research, he has defined three principles to build soil fertility; minimal

2021/11/18

Imagine improving both the efficiency and safety of your team with autonomous drone vineyard spraying. That is exactly what David Goldfarb and the team at Clos de la Tech are trialing in their vine rows. Although this technology has been used in Japan for a number of years, it is new to the United States. Initially, they looked to drones as a way to scout for pests. Spraying was limited due to the small capacity of the machines. Then an advancement inspired by COVID stadium sanitation standards

2021/11/04

The first pillar of any successful IPM (Integrated Pest Management Program) is to know the pest you want to manage. Emily Symmes, Entomologist and Technical Field Manager at Suterra, addresses the basics of vine mealybug (VMB) in grapes in this expert from the 2020 Sustainable Ag Expo. VMB are phloem eaters, piercing the trunk, canes, and berry clusters and vectoring leafroll-associated viruses. In high populations, they will weaken the vines and can cause vine decline and death. Their rapid

2021/10/07

UV lamps have been used in the medical field, food processing, and sterilization for 75 years but application on plant disease management only began in the 1990s. UV light is a natural component of sunlight. The most harmful wavelengths like UVC are screened out by our ozone layer. DNA damaging UVB does reach the surface, however, most organisms can utilize blue light to repair the damage.

How can values, beliefs, and attitudes around irrigation improve water efficiency? That is exactly what a recent California Department of Water Resources (DWR) grant project aimed to discover. Grant recipient, Vineyard Team, worked with 59 growers over three years to conduct irrigation-related behavior interviews, Distribution Uniformity evaluations, and determine if continued interaction (nudges) with the grower would increase the adoption of irrigation best management practices in vineyards.

2021/09/02

Plant SAP analysis gives farmers insight into how the plant can take up and mobilize nutrients. Traditional tissue testing is usually done at the top of the plant, sampling only the youngest leaves. SAP Analysis is actually a pair of tests, comparing nutrients in young and old leaves to see what is being taken up today and how the nutrients are moved around. Test results compare levels in young and old leaves across 24 different nutrients. One important comparison is Nitrogen efficiency, so the

Numerous vineyards have utilized sheep and goats for grazing but most only during the winter. Kelly Mulville was on a mission to design a vineyard for year-round grazing to restore the ecosystem with livestock. The challenge was to find a vineyard design where the animals could not eat the vines. In a partnership with Paicines Ranch in California, Kelley and the team utilized the Watson Training System which holds the cordon wire at 66 inches. The vineyard incorporated nine grape varieties and

2021/08/05

A healthy soil has hundreds of different species of microbes while a depleted one may only have one dozen. A number of common viticulture practices are not conducive to a healthy soil biology so Dave Olson of Sustainable Growing Solutions is looking at how we can improve soil quality with microbes, ultimately improving plant quality. This process can be foliar with soil inoculations over time. Microbes do not colonize all at once so it important to add them over a period of time so that some will

112: How Deficit Irrigation Impacts Soil Quality

Sustainable Winegrowing ·

2021/07/15

Deficit irrigation is used in winegrape production to keep berries small and enhance the flavor of wines, particularly with reds. Joan Davenport, Emerta Professor of Soil Sciences at Washington State University says to get an accurate measure of soil moisture, you need to focus monitoring where the roots are. These measurements are ideally taken about 15 to 20 inches from the vines. Deficit irrigation can lead to a buildup of salt and sodium, negatively impacting soil quality. Salts cause root
