Abstract

Viticulture in Codpa is developed in altitude under a subtropical climate, where the vines present a series of physiological disorders due to the lack of chilling hour accumulation. The goal of this research was to characterize the soil and climate conditions of the Codpa Valley vineyards. The results showed that soil pH of the vineyards of Codpa Valley was alkaline, whereas the soil electrical conductivity varied from 0.81 to 2.10 mmhos/cm. Soil nitrogen content was low (? 20 ppm), whereas soil boron content was high (? 2.00 ppm). Climate of Codpa is characterized as intermediate according to the Growing Season Temperature (GST = 16.7 ºC), and cool by the Huglin Heliothermal Index (HI = 1873.1 heat units). Codpa presents cold nights according to the Cold Night Index (CI = 9.8 ºC). The trend for the maximum temperature and for the sum of the mean and maximum spring temperatures in Codpa was highly significant for the period from 1985 to 2015. Thereby, the maximum temperature increased by 0.044 ºC, and the sum of the mean and maximum temperatures spring increased by 3.18 and 5.59 heat units, respectively for each year in Codpa. © 2023 by the Author(s).
