NRCS SOIL SURVEY INFORMATION IMPORTANT TO VINEYARDS

NRCS SOIL SURVEY INFORMATION IMPORTANT TO VINEYARDS

Vineyards have two environments – one above ground and another below ground.  The above ground environment is our visible domain where we can witness both atmospheric events and grapevine responses to them.  In contrast, our ability to observe events underground, or at least infer them, is very limited, relying mainly on sensor readings, periodic analysis results for soil samples, and recognizable vine foliage responses to changes in soil conditions, such…

Micronutrient Management in Vineyards

Micronutrient Management in Vineyards

Micronutrients are mineral elements required in small quantities by plants for normal growth and development.  They include iron, manganese, copper, zinc, boron, molybdenum, and chloride.  The micronutrients tend be overshadowed by the macronutrients, especially nitrogen and potassium, in the minds of many of us in the wine grape industry.  In fact, micronutrients are often referred to as “minors”.  With regard to grapevines, however, there is nothing minor about them.  Small…

Nitrogen Part II: Effective Nitrogen Management for Vineyards

In my last Lodi Growers Coffee Shop article, we considered nitrogen’s pivotal role and  impacts on grapevines. In this article, we investigate nitrogen management. As in the management of all mineral nutrients, vine nutrient demand is the place to begin development of a nitrogen management strategy. Seasonal Nitrogen Demand In well-managed vineyards, the harvested fruit represents the greatest net annual nitrogen loss (fig. 1). The amount of nitrogen in mature…

Nitrogen Part I: The Pivotal Mineral Nutrient in Vineyards

Nitrogen Part I: The Pivotal Mineral Nutrient in Vineyards

In wine grape growing, nitrogen (N) receives a great deal of attention for several reasons. First, N is a component of numerous molecules essential for life, including a wide array of proteins, nucleic acids, and chlorophyll. As a result, nitrogen has broader influence on grapevine growth and fruit production than any other mineral nutrient. When vines contain too little nitrogen, photosynthesis is depressed, growth is inhibited, and their foliage appears…

Negotiation Tips for Winegrape Growers

Grape growers are expected to be competent at a wide-ranging of tasks.  For example, they have to be good at equipment maintenance, pruning, labor relations and finances, to list but a few of the skills that are necessary to succeed as a grower. Of all the skills that a grower must have, perhaps the most important is the ability to negotiate. Negotiation is a constant necessity for a grower both when…

In the Vineyard with Paul Verdegaal

The 2015 Harvest came to a close by the second week of October.  Harvest began on the earliest date that most anyone can remember. It is an interesting year to say the least, but there have been previous harvest starts in July.   Let’s look back on some local observations from the recent past. Checking some of my notes; Zinfandel for red was picked in August in 2001, 2004 and…

Lodi Growers Boost Knowledge about Grape Pest Management

The Lodi Winegrape Commission and the University of California Cooperative Extension (UCCE) have a long history of working together to achieve our common goal of communicating research insights about best management practices to Lodi growers. In light of this, the Commission partnered with UCCE to provide Lodi winegrowers with the most up to date grape pest management information. During 2014 and 2015 the Commission hosted a series educational meetings that were based around…

Maximizing Cover Crop Benefits Through Selection and Management

Maximizing Cover Crop Benefits Through Selection and Management

Cover crops provide an array of important benefits to vineyards.  These include direct benefits that improve soil tilth, build soil structure, enhance the root environment, limit soil erosion, and modify the vineyard environment.  Through these, we can gain additional, indirect benefits in the management of soil moisture, mineral nutrients, grapevine growth vigor and balance, wine grape yield and quality, and grapevine pests.  While any type of cover crop will provide…

Managing Vineyard Mineral Efficiency Beyond the Four R’s

Managing Vineyard Mineral Efficiency Beyond the Four R’s

External pressures on mineral nutrient use in  vineyards come from several directions. On the one hand, to remain competitive, we need to contain applied mineral nutrient costs even while costs of some fertilizers are being driven upward by the growing global fertilizer demand. On the other, our society increasingly expects applied mineral nutrient resources to either stay in vineyards or to leave only with the harvested fruit. These pressures, originating from disparate…

Ciatti Global Market Update – September 2015

“Like sands through the hourglass, so are the days of our lives” was a quote television catchphrase from a long‐running soap opera, which is appropriate for this global market update. With harvest in full swing in the Northern Hemisphere, buyers are truing up inventories and ensuring all programs will have good quality supply. The question at hand is:  what varietals will be short, what varietals will be long, and from where? Meanwhile,…
