  • \n\tPossibilit\u00e9s\n\tde chute de neige entre novembre et avril.\n\t<\/li>
  • \n\tLe\n\tnombre de jours de gel varie entre 100 et 150 par an.\n\t<\/li>

    \n\tTopographie <\/h4>\n\n\n\n

    \nLa\nparcelle se localise sur une plaine limit\u00e9e au nord par le Puy de\nMontjuger (1142 m) et au sud par le Puy de Monchal (1094 m).<\/p>\n\n\n\n

    \nLe\nsubstrat g\u00e9ologique est constitu\u00e9 de projections basaltiques qui\nont pour origine les \u00e9ruptions des \u00e9difices volcaniques alentours\n(Puys de la Vache et de Lassolas).<\/p>\n\n\n\n

    \nCe\nrecouvrement est de nature basique, constitu\u00e9 de scories fines.<\/p>\n\n\n\n

    \nLes\nsols sont du type brun andique, ils sont sains, frais et pr\u00e9sentent\nune bonne r\u00e9serve utile.<\/p>\n\n\n\n
