Les inhibiteurs d\u2019ur\u00e9ase ralentissent la transformation de l\u2019ur\u00e9e en ammonium, qui peut se transformer en gaz ammoniac et \u00eatre perdu par volatilisation. Cela signifie qu\u2019il reste moins d\u2019azote utilisable dans le sol pour la production agricole.<!--more--><\/p>\n<h2>Quand devriez-vous envisager d\u2019utiliser des stabilisateurs d&#039;azote?<\/h2>\n<p>Les stabilisateurs d&#039;azote peuvent \u00eatre b\u00e9n\u00e9fiques si vous appliquez 100 % de votre azote d\u00e8s le d\u00e9part, si vous appliquez de l&#039;azote liquide en surface comme support d&#039;herbicide ou si vous \u00e9pandez de l&#039;ur\u00e9e mais qu&#039;elle n&#039;est pas compl\u00e8tement incorpor\u00e9e. Si vous avez des granules visibles d&#039;azote \u00e0 la surface du sol apr\u00e8s l&#039;application, le risque de volatilisation est plus \u00e9lev\u00e9, en particulier dans des conditions chaudes et s\u00e8ches.<\/p>\n<h2>Les 3 formes de perte d\u2019azote :<\/h2>\n<p><strong>La volatilisation<\/strong> est une perte d&#039;azote au-dessus du sol et se produit lorsque les enzymes ur\u00e9ases du sol d\u00e9composent les mol\u00e9cules d&#039;ur\u00e9e en gaz ammoniac. Cela peut se produire lorsque l\u2019engrais est \u00e9pandu \u00e0 la vol\u00e9e ou en bandes peu profondes par temps chaud, ou lorsque l\u2019azote est appliqu\u00e9 sur un sol humide suivi de conditions s\u00e8ches. Les sols dont le pH est plus \u00e9lev\u00e9 sont g\u00e9n\u00e9ralement plus sujets \u00e0 la perte d\u2019azote.<\/p>\n<p>La perte d&#039;azote <strong>par d\u00e9nitrification<\/strong> se produit sous terre lorsque l&#039;azote nitrique est reconverti en formes gazeuses et se produit le plus souvent dans les sols chauds mal drain\u00e9s ou gorg\u00e9s d&#039;eau.<\/p>\n<p><strong>Le lessivage<\/strong> se produit lorsque l&#039;azote est perdu sous terre lorsque le mouvement descendant de l&#039;eau transporte le nitrate charg\u00e9 n\u00e9gativement sous la zone racinaire.
