Le Dr Ikbel Chaieb, chercheur au Centre r\u00e9gional de recherche en horticulture et en agriculture biologique de Chott Meriem, porte un regard nouveau sur nos pratiques culturales. Selon ce chercheur, le labour de la terre pourrait n’\u00eatre qu’un \u00ab faux acte \u00bb de bienfaisance, tant \u201cles herbes sauvages jouent un r\u00f4le crucial dans la protection des sols\u201d. \u201cLoin d’\u00eatre des parasites, ces plantes spontan\u00e9es agissent comme une infrastructure naturelle : leurs racines consolident la terre, la maintiennent a\u00e9r\u00e9e et stable, facilitant ainsi l’infiltration de l’eau tout en freinant l’\u00e9rosion\u201d, pr\u00e9cise le chercheur.<\/span><\/p>\n

Pour lui, cette couverture v\u00e9g\u00e9tale constitue \u201cun rempart essentiel contre les al\u00e9as climatiques\u201d. En p\u00e9riode de s\u00e9cheresse, elle emp\u00eache l’\u00e9vaporation rapide de l’eau et pr\u00e9serve l’humidit\u00e9 du sol, l\u00e0 o\u00f9 le labour laisse la terre \u00e0 nu, expos\u00e9e au dess\u00e8chement du soleil et du vent. Au-del\u00e0 de la r\u00e9gulation thermique, ces herbes favorisent une biodiversit\u00e9 indispensable en offrant un refuge aux pollinisateurs et aux insectes pr\u00e9dateurs qui luttent naturellement contre les parasites.<\/span>
\n<\/span>\u201c\u201dSous la surface, l’absence de perturbation m\u00e9canique permet l’\u00e9panouissement d’un sol vivant, o\u00f9 les micro-organismes et les vers de terre assurent la fertilit\u00e9 n\u00e9cessaire \u00e0 la croissance des arbres de mani\u00e8re totalement naturelle\u201d Et Ikbel Cha\u00efeb d\u2019ajouter: \u201cen renon\u00e7ant au labour, on pr\u00e9serve \u00e9galement le carbone stock\u00e9 dans le sol, participant ainsi activement \u00e0 la lutte contre le changement climatique\u201d. \u201cCette approche permet enfin de r\u00e9duire drastiquement les co\u00fbts li\u00e9s au carburant, aux machines et aux intrants chimiques, prot\u00e9geant ainsi durablement l’homme et son environnement\u201d, a-t-il conclu.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
