Plan de fertilisation par phases de culture : quoi appliquer à chaque étape
Réponse rapide : chaque phase de la culture a un besoin principal. Sol : matière organique (acides humiques). Repiquage : phosphore, acides aminés et algues pour enraciner. Débourrement et croissance : acides aminés et oligo-éléments. Floraison : bore et biostimulants. Nouaison et grossissement : calcium, acides aminés et algues. Maturation : potassium pour le calibre, la couleur et le sucre. Stress : acides aminés, algues et protection spécifique. Ce guide résume quoi appliquer à chaque moment et renvoie vers les guides détaillés.
1. Préparation et amélioration du sol
Un sol avec une bonne structure et une vie microbienne active valorise beaucoup mieux la fertilisation.
Plus de détails : acides humiques et amendements organiques .
2. Repiquage et implantation
Trasplante Vital : acides aminés, algues, phosphore et potassium pour un démarrage racinaire rapide. Fertirrigation 1-1,5 L/ha juste après le repiquage.
Ondara Maxima (Ecklonia maxima) et Fosforia pour renforcer la racine.
3. Débourrement et croissance végétative
Plus de détails : acides aminés pour les plantes et carences en fer, zinc et manganèse .
4. Floraison
Plus de détails : bore et molybdène pour la floraison et la nouaison .
5. Nouaison
Savia Vital : acides aminés avec oligo-éléments pour des fruits plus gros et plus uniformes.
Impulso Fruital : glycine bétaïne pour réduire l'avortement des fleurs, en particulier sur melon et pastèque.
Ondara : algues pour l'énergie supplémentaire nécessaire à la nouaison.
6. Grossissement du fruit
Plus de détails : le calcium pour les cultures .
7. Maturation
Potassium pour le calibre, la couleur et les degrés Brix : Potasia Acida , Potasia Plus ou Potasia 20 .
Sur les fruits exposés au soleil (pomme, melon, pastèque, orange, tomate), Solaria réfléchit le rayonnement ultraviolet et réduit la température de la peau du fruit. Foliaire 20-30 L/ha.
Plus de détails : potassium et phosphore .
8. Situations de stress
Pour chaque traitement : eau et bouillie
Avant toute application, vérifiez le pH de l'eau. Un correcteur comme Equilibrio pH et un adjuvant comme Cumbre aident à mieux valoriser chaque produit. Guide : comment corriger le pH . Pour renforcer la plante de façon préventive, consultez cuivre, soufre et silicium .

Questions fréquentes
Quel engrais appliquer en floraison ?
En floraison, la priorité est le bore (pour la fécondation) associé à des biostimulants d'acides aminés ou d'algues. Un excès d'azote à ce stade favorise le feuillage au détriment de la fleur.
Que faut-il appliquer pour le grossissement du fruit ?
Pendant le grossissement, du calcium pour la fermeté, des acides aminés et des algues pour la division cellulaire et, à l'approche de la maturation, du potassium pour le calibre et la couleur.
Que faire après une chute de grêle ?
Appliquer des acides aminés à assimilation rapide (Impulso ou Savia Premium) dans les premiers jours pour aider la plante à récupérer, et envisager un calcium foliaire pour renforcer les fruits endommagés.
