Vineyards – Measurement of climatic parameters

The most important information for viticulture

Specific climatic and habitat conditions affect the growth and yielding of vine shrubs. Often, the terrain and specificity of the terrain, type of buildings or type of nearby vegetation can have a significant impact on the temperature distribution in a given place. Not every strain will grow properly in given conditions, so when establishing or running a vineyard it is worth checking whether the conditions in this place will be appropriate for the selected strain.
In order to run a vineyard, you should monitor values such as:

  • THE LENGTH OF THE GROWING SEASON (LGS)
  • HUGLIN INDEX (HUGLIN HELIOTHERMAL INDEX)
  • THE COOL NIGHTS INDEX (CNI) 
  • SAT and GDDC 

Efento wireless temperature sensors are equipped with a memory of 60,000 measurements, thanks to which they enable data collection from the whole season with a ten-minute recording interval. After downloading data from the sensor memory, the Efento Logger application will list all the parameters.

The installation of the Efento wireless temperature sensor boils down to placing it in a place that prevents it from flooding and placing the measuring probe in a cover reducing the influence of sunlight on temperature measurement (the cover is not included in the set). The device has been designed so that anyone can configure it. All you need to set up is an Android smartphone with the free Efento Logger mobile application installed. System configuration will take you less than 15 minutes!

THE LENGTH OF THE GROWING SEASON (LGS) is the number of days with average daily temperatures above 10 degrees Celsius. Depending on the grapes variety, the region is generally considered suitable for wine growing if the LGS value is higher than 182 days.

HUGLIN INDEX (HUGLIN HELIOTHERMAL INDEX) is the sum of active temperatures in the period from the beginning of April to the end of September. HI takes into account the length of the day and the average and maximum daily temperatures. It is divided into 6 climate classes, from very cold (HI ≤ 1500) to very warm (HI> 3000). The heliotermic index using sums of air temperatures and latitudes is one of the most common methods used to identify suitable areas for viticulture. The Efento Logger application uses the GPS signal to determine the user’s position and include it for the calculation of the Huglin index. As a result, the index values are precisely calculated for the specific location where wine growing is planned

THE COOL NIGHTS INDEX (CNI) specifies the relative measure of maturation potential, equal to the average minimum temperature during the month before harvesting. In the northern hemisphere: CI = average minimum temperature in September, in the southern hemisphere: CI = average minimum temperature in March

SAT and GDDC is the sum of average daily temperatures, determined throughout the season, calculated as the average temperature value of all days for which it has reached at least 10 degrees Celsius (active days). In the case of GDDC, the product of the number of active days and 10°C shall be subtracted from the received SAT value.
