Riz (Oryza sativa. L) étant une plante de silicicolus absorbe le Si sous forme d'acide mono silicique (H4 Si O4) par respiration aérobie active et accumule plusieurs fois plus que ceux des autres macronutriments du milieu de culture, ce qui conduit à un épuisement drastique du Si sur la culture intensive du riz. Les enquêtes menées dans la zone du delta de Cauvery ont révélé que 62 % de la superficie est faible en Si disponible et 30,5 % de superficie est faible en K disponible. Par conséquent, il est impératif d'utiliser les ressources existantes comme meilleur substitut de Si. Les centrales thermiques en Inde produisent de grandes quantités de cendres volantes chaque année et leur utilisation est limitée, ce qui est également une bonne source de Si et K. Par conséquent, des enquêtes menées à l'aide de cendres volantes, de bactéries solubilisantes de silicate (SSB) et de fumier de ferme (FYM) à la fois comme étude d'incubation et expérience sur le terrain dans les sols faibles, moyens et élevés en Si. La libération de Si était plus prononcée 60 jours après la submersion. Application de niveaux gradués de cendres volantes à 25 t ha-1 avec 2 kg ha-1 de SSB et 12,5 t ha-1 FYM a enregistré le rendement plus élevé et reconstitué le sol Si. Cependant, les effets étaient plus prononcés dans les sols en silicium faible et moyen.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Rice (Oryza sativa. L) being a silicicolus plant absorbs Si in the form of mono silicic acid (H4 Si O4) through active aerobic respiration and accumulates several fold greater than those of other macronutrients from the growing medium which leads to drastic Si depletion on intensive rice cultivation. Investigations carried out in Cauvery Delta Zone revealed that 62 per cent of area is low in available Si and 30.5 percent area as low in available K . Hence there is an imperative need to utilize existing resources as the best substitute of Si. Thermal power stations in India produces large quantities of fly ash annually and its utilization is limited which is also a good source of Si and K. Hence investigations carried out using Fly Ash, silicate solubilizing bacteria (SSB) and farm yard manure (FYM) both as incubation study and field experiment in low, medium and high Si soils. Release of Si was more pronounced at 60 days after submergence. Application of graded levels of fly ash at 25 t ha-1 with 2 Kg ha-1 of SSB and 12.5 t ha-1 FYM registered the higher yield and replenished the soil Si.However the effects were more pronounced in low and medium silicon soils. 248 pp. Englisch.
