Lodi Acreage and Potential 2014 Crop Size

Lodi Acreage and Potential 2014 Crop Size

Here at Allied Grape Growers AGG, we recently combed through the 2013 Grape Acreage Report published by the California Ag Statistics Service.  As we have done over the years, we analyzed every corner of the report, identifying missing acres and creating a better understanding of the true winegrape acreage planted in the state, by district and variety.  Since the report is voluntary we know data will be missing, but fortunately…

Remote Sensing for Vineyard Pest Management

Remote Sensing for Vineyard Pest Management

Remote sensing is a valuable tool for vineyard managers to assess several aspects of their viticultural operations, including pest management programs. Remote sensing refers to the use of aircraft or satellites to provide pictures or digital images of vineyards. Synoptic images taken from above vineyards often provide insight into patterns in vine growth that are more difficult to discern from the ground. Subtle differences that may go unnoticed in the…

Quick and Easy Pesticide Use Reporting

In 1990 California became the first state to require full reporting of agricultural pesticide use. Under the full use reporting regulations growers are required to report monthly the pesticides they use to the agricultural commissioner of the county in which the pest control work was done. Specifically, there are 17 pieces of information that the grower is required to report for each pesticide application: month and year of the application(s)…

Practical Uses of Aerial Imagery in Lodi Vineyards

Using Aerial Imagery to enhance farm productivity was once out of reach, but it is now much more accessible on a timely basis for an affordable price.   When you hear phrases like Color Infrared (CIR), Normalized Difference Vegetation Index (NDVI) and thermal imagery it may conjure up some forensic type of scientific data analysis that only a PhD could do, however, it is very much the opposite. In today’s world,…

In the Vineyard with Paul Verdegaal

The 2014 season started off with Chardonnay budbreak just slightly ahead of average about 6 days, on March 9th.  As in 2013 warm daily maximums, but below average nightly lows have allowed for a below average accumulation in Growing Degree Days (GDD).  Drought conditions have continued and intensified from last season. Fortunately significant rain events in February and early March were perfectly timed to alleviate a lot of stress on…

A Model to Establish Economically Sustainable Cluster Thinning Practices

A Model to Establish Economically Sustainable Cluster Thinning Practices

Vineyard management practices that improve fruit quality are only economically viable if the fruit price is high enough to offset increased costs to growers. For example, cluster thinning can help growers avoid delays in ripening and improve fruit quality, but it reduces the amount of harvestable fruit. For a grower to consider cluster thinning as a management tool, the loss in income from lower overall yields and increased labor costs…

Lodi Soils Roadshow: A Photo Essay

The Soil Roadshow, held on April 14, took 30 local winegrowers on a tour of three different yet common soil types found within the Lodi region: San Joaquin, Tokay, and Corning/Redding. UCCE soil scientist Toby O’Geene and UCCE farm advisor Paul Verdegaal, along with local viticulturist and Coffee Shop contributor Stan Grant, shared their knowledge about these soils. Winegrapes are grown extensively in each of these soils and growers must manage their vineyards to…

How to Learn Spanish

How to Learn Spanish

Many grape growers would like to learn to speak Spanish in order to communicate more effectively with farmworkers who are more comfortable communicating in that language.  However, the task of learning a foreign language just seems to be too difficult.  This conclusion is often arrived at after several years of studying a foreign language in high school or college without good results. Because I have studied 8 different languages over…

Soil Moisture Monitoring

April 8th, 2014
Soil Moisture Monitoring

Here are the basic facts of water in vineyards. Water resides in the soil, the atmosphere, and the grapevines. The water in these vineyard elements is interconnected and forms a continuum. In California, after the last spring rain, water moves mostly from the soil to the atmosphere, either directly through evaporation or indirectly through the vines as they transpire. The following is another fact. Efficient and low risk water management…
