117: Grapevine Mildew Control with UV Light

Sustainable Winegrowing ·

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. David Gadoury, Plant Pathologist at Cornell University, is part of a large team of international researchers

Sustainable Winegrowing ·

2021/09/16

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.

115: Examining Plant Nutrient Mobility with SAP Analysis

Sustainable Winegrowing ·

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

114: Designing a Vineyard for Year-Round Sheep Grazing

Sustainable Winegrowing ·

2021/08/19

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

113: Microbial Inoculants for Soil Health

Sustainable Winegrowing ·

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

Every vineyard has a portion of the property that is non-productive, but are there ways to maximize the benefits of this land? Fintan du Fresne, General Manager and Winemaker for both Chamisal Vineyards and Maine Wines and Christian Rodriguez, Assistant Vineyard Manager at Chamisal Vineyards found the answer to this question with a Miyawaki Mini-forest. Conceived by Japanese botanist Akira Miyawaki, these mini-forests can take be developed in spaces as small as 30 square yards. Development of a

Vineyard development begins with the soil. Steve Vierra, Director of Vineyard Operation at Derby Wine Estates and Certified Professional Soil Scientist, has developed many vineyards since the 1990s and always begins with a site evaluation to determine what is actually plantable. This includes a deep dive into all aspects of the prospective vineyard including climate, rain fall, aspect, slope, rootstock, soil types, and best varieties to create a self-sustaining vine. The goal is to develop a

2021/05/20

There is no doubt that water is a precious resource, particularly in drought prone regions like California. It is very important for growers to measure soil moisture and there are a bevy of technological devices available to utilize. From soil moisture probes to pressure bombs, these tools are helpful but, they only provide data on once specific area at a time and many are time consuming to use. Today, there is a lot of free satellite data available and that data is being captured by Irriwatch

2021/05/06

Using sheep to graze vineyards has many benefits including lowering the carbon footprint, fewer tractor passes, and reduced herbicide use. Kelsey Brewer, Ph.D. Candidate at the University of California at Davis has been researching how these living lawnmowers impact nutrient and energy flows in the eco system. When tractors were replaced by sheep, the research team found that vineyards had 1.3 times more organic matter and nitrogen plus twice as much available soil nitrogen in the soil. Grazed

What, bury charcoal in the vineyard? Biochar is a specialized form of charcoal made from waste woody biomass at high temperature in the absence of oxygen. We know soil organic matter is important for the health of any crop. It turns out the use of charwood (biochar) goes back to ancient civilizations and it can be found naturally in soils from fire events. Doug Beck, Science Officer at Monterey Pacific in Monterey California, recently conducted a four-year trial to test the impacts of biochar and

2021/04/01

In 2008 the oversupply of Sauvignon Blanc coupled with the financial crisis lead to trialing shaking to remove berries in New Zealand for the very first time. A few years later, the New Zealand Winegrowers Society funded a three-year grant to test the impacts of shaking on dropping fruit, wine quality, and botrytis. Mark Allen of Allen Vineyard Advisory explains that because shaking the vine four to six weeks after fruit set does cause some damage to the canopy and berries, pathologists assumed that

The small Priorat region in Spain has a fascinating history dating back to the Moors in the 8th century, to the birth of its wine production for a local monastery in the 1100s to the near complete devastation of its vineyards by phylloxera in the late 19th century. Replanting began in earnest in the 1950s and top reviews by Robert Parker in the 2000 helped solidify this area as a top wine region in Spain.

The resource concentration hypothesis looks at how the advent of modern agriculture as monoculture created an environment where pests can grow faster because their resource, the crop, is more prevalent. Biodiversity is fundamental for pest management and Daniel Paredes, Postdoctoral Fellow at the University of California Davis, in the department of Wildlife Fish and Conservation Biology, is studying how sustaining natural habitat around vineyards can increase biodiversity.

2021/02/04

While grape production does not require extensive water use and the majority of vineyards in the Pacific North West are drip irrigated, drought conditions in recent years have led growers to seek more efficiencies to reduce water use. Pete Jacoby, Professor of Crops and Soil Sciences at Washington State University knows that in a traditional drip irrigated vineyard, water is lost through evaporation plus plants loose about 90 percent of the water they take up through transportation. Most sub-surface
