Vineyard NutritionJust as in humans, nutritional balance within the vine is essential to consistent fruit quality and quantity. How do you balance nutrition in the vineyard? While the majority of nutritional management can be dealt with prior to planting, such as adjusting soil pH and organic matter, vineyard soil management is a continual process and requires monitoring to ensure healthy, productive vines. It's better to maintain proper soil health practices than to try to correct problems when leaf symptoms are visible. How can you keep an eye on vineyard nutrition? Soil and petiole testing will help you monitor nutrients available in the soil and in the plants. We recommend doing BOTH soil and petiole testing to verify that what you have available in the soil is actually getting into the vines. If a petiole test result indicates a deficiency, but soil test results indicate adequate levels of a nutrient, an alternative problem, such as improper soil pH or inadequate water drainage, could be the culprit.

Lake Erie Grape belt low temperatures in Feb 2015 reached -19 to -29 degrees F and this has caused variable damage to fruiting buds of grapevines. Viticulture Specialist, Luke Haggerty, and the CLEREL staff are evaluating the extent of bud damage from several vineyards across the region.

Fruit Thinning in Wine Grape Varieties
by Hans Walter-Peterson
Cluster thinning is often employed in wine varieties to help achieve a certain crop load and quality level. The amount of fruit to remove from a given vine is a function of many individual factors, including vine vigor, variety and rootstock, growing season conditions, and even the contract with the buyer. Because conditions in eastern North America can vary greatly from year to year, the need for cluster thinning and the amount to be removed can also change every season. The goal of cluster thinning, then, is to achieve both the quality and quantity parameters that will satisfy both the grower and their buyers.

Soil and petiole testing can provide a clear picture of what is going on in your vineyard. The soil tests will determine what nutrients are available to be taken up by the vines' roots, and the petiole tests will show whether or not the roots are actually absorbing those nutrients. Once you have the soil tests, you have one side of the story, and petiole tests will give you the other side of the vine nutrient story.
