  • Modèles d’utilisation du phosphore dans les vertisols
    B.S. Dwivedi / G.D. Sharma / Risikesh Thakur
    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 pro...

  • Verwertungsmuster von Phosphor in Vertisolen
    B.S. Dwivedi / G.D. Sharma / Risikesh Thakur
    Das Problem bei Phosphatdüngern besteht darin, dass bei der Ausbringung auf Schwarzerden (Vertisolen) ein großer Teil davon (80-85 %) im Boden gebunden wird und nur ein kleiner Teil (15-20 %) den Pflanzen zur Verfügung steht. Die gebundenen oder nicht verfügbaren Formen werden durch PSB durch die Produktion organischer Säuren und des Enzyms Phytase gelöst und mineralisiert, wod...

  • Modello di utilizzo del fosforo nei vertisuoli
    B.S. Dwivedi / G.D. Sharma / Risikesh Thakur
    La difficoltà con il fertilizzante fosfatico è che, quando viene applicato su terreni neri (Vertisol), una grande frazione di esso viene fissata (80-85%) nel terreno e solo una piccola parte (15-20%) è disponibile per le piante. Le forme fisse o non disponibili vengono solubilizzate e mineralizzate dal PSB producendo acidi organici e l’enzima fitasi, che è poi disponibile per l...

  • Wykorzystanie fosforu w glebach typu vertisol
    B.S. Dwivedi / G.D. Sharma / Risikesh Thakur
    Problem z nawozami fosforowymi polega na tym, że po ich zastosowaniu na glebach czarnych (wertisolach) znaczna ich część (80-85%) ulega wiązaniu w glebie, a tylko niewielka część (15-20%) jest dostępna dla roślin. Formy związane lub niedostępne są rozpuszczane i mineralizowane przez bakterie PSB poprzez wytwarzanie kwasów organicznych oraz enzymu fitazy, dzięki czemu stają się ...

  • Optical Fiber Systems and Their Components
    A.B. Sharma / M.M. Butusov / S.J. Halme
    This book is intended to be an introductory text for engineers and physicists who are likely to be involved in the area of optical fiber communications. Its purpose is to provide the student with an explanatory text that can al so be used for 'self-study'. Thus, key theoretical resul ts have been rather thoroughly derived, and detailed explanations have been given wherever cer­...

  • The Cyst Nematodes
    S.B. Sharma
    When Franklin published her book on cyst nematodes in 1951, the cyst nematodes were already known as serious pests of brassicas, cereals, potatoes and sugar beets. However, at that time this group of nematode, with about 12 species, was considered tobe largely temperate in distribu­ tion. Now a total of 105 species (including those that are considered...
