Dans le sud-ouest de l'Ontario, nous connaissons des temp\u00e9ratures extr\u00eames cette semaine. Ces temp\u00e9ratures \u00e9lev\u00e9es ont un impact n\u00e9gatif sur la photosynth\u00e8se et la respiration, ce qui entra\u00eene la perte de la capacit\u00e9 de votre plante \u00e0 fonctionner ou \u00e0 cro\u00eetre normalement.
Pour le ma\u00efs et le soja, on estime que la perte de rendement est due \u00e0 des facteurs de stress abiotiques (s\u00e9cheresse ou chaleur) pour plus de 65% et \u00e0 des facteurs biotiques (mauvaises herbes, insectes, maladies) pour moins de 10%.<\/p>\n<\/div>

BioLiNE Acides Fulviques<\/strong>
Nos produits peuvent \u00eatre appliqu\u00e9s par voie foliaire ou par irrigation, seuls ou en combinaison avec d'autres intrants. Ajoutez 500-750 ml d'acides fulviques BioLiNE \u00e0 votre m\u00e9lange de post-lev\u00e9e pendant cette p\u00e9riode de temp\u00e9ratures \u00e9lev\u00e9es. Nos acides fulviques aident les plantes \u00e0 surmonter le stress d\u00fb \u00e0 la chaleur et \u00e0 la s\u00e9cheresse de plusieurs fa\u00e7ons :
\ud83c\udf31 Maintient la teneur en eau relative des feuilles et am\u00e9liore le soutien en nutriments - maintient l'\u00e9quilibre et le fonctionnement normal des plantes.
\ud83c\udf31 Augmente le taux d'assimilation du dioxyde de carbone - favorise la photosynth\u00e8se et la croissance des cultures
\ud83c\udf31 Am\u00e9liore l'efficacit\u00e9 de l'utilisation de l'eau (irrigu\u00e9e ou non) - permet \u00e0 l'eau limit\u00e9e d'aller plus loin dans la plante
\ud83c\udf31 Maintient l'\u00e9quilibre \u00e9lectrochimique - emp\u00eache l'accumulation de m\u00e9taux lourds potentiellement toxiques
\ud83c\udf31 Ouverture des stomates - maintient l'\u00e9vapotranspiration pour \"refroidir\" la plante
\ud83c\udf31 Augmente les enzymes antioxydantes - am\u00e9liore la capacit\u00e9 de la plante \u00e0 se d\u00e9fendre contre les esp\u00e8ces oxydatives r\u00e9actives (ROS) destructrices.<\/p>","protected":false},"excerpt":{"rendered":"
