This item is printed on demand - it takes 3-4 days longer - Neuware -Le problème avec les engrais phosphatés est que, lorsqu'ils sont épandus sur des sols noirs (vertisols), une grande partie (80 à 85 %) est immobilisée dans le sol et seule une petite fraction (15 à 20 %) est disponible pour les plantes. Les formes immobilisées ou indisponibles sont solubilisées et minéralisées par les bactéries solubilisatrices de phosphate (PSB) grâce à la production d'acides organiques et de l'enzyme phytase, qui deviennent alors disponibles pour les cultures. Cela augmente également l'efficacité d'utilisation du superphosphate. Le fumier de vache (FYM) améliore également la disponibilité du phosphore grâce à la production d'acides organiques tels que le citrate, l'oxalate, le lactate, etc. lors de la décomposition, qui retiennent l'aluminium (Al) et le fer (Fe). Ainsi, la fixation du P sous ses formes inorganiques, c'est-à-dire sous forme de phosphate d'aluminium et de fer, est réduite par l'ajout d'engrais organiques. La technique du traceur de rapport fournit de nombreuses informations sur la quantité de phosphore absorbée par les plantes et la quantité de phosphore fixée dans le sol, ainsi que sur la mobilité du P dans le sol et sa disponibilité pour les plantes tout au long de leur cycle de vie. 76 pp. Französisch.…
