O que acontece quando uma área é irrigada em excesso ?

\huge \frak \purple{Answer}

La sur-irrigation peut provoquer un drainage profond de la montée des nappes phréatiques qui peut conduire à des problèmes de salinité d'irrigation nécessitant un contrôle de l'eau par une certaine forme de drainage des terres souterraines. Cependant, si le le sol est sous irrigué, il donne un mauvais contrôle de la salinité du sol, ce qui entraîne une augmentation de la salinité du sol avec une accumulation conséquente de sels toxiques à la surface du sol dans les zones à évaporation élevée. Cela nécessite soit une lixiviation pour éliminer ces sels et une méthode de drainage pour évacuer les sels. L'irrigation avec de l'eau saline ou riche en sodium peut endommager la structure du sol en raison de la formation d'alcaline.
