Description

Effets des sources indignes de silicium sur la fertilit des sols by Neeraj Kumar Vaishya Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Les effets du silicium (Si) sur l'état des nutriments minéraux dans le sol et les plantes ne sont pas bien étudiés. L'application de Si pourrait considérablement augmenter le rendement du riz et atténuer le stress abiotique, en particulier la sécheresse. On sait que le Si a un effet favorable sur les plantes dans des conditions de stress. Une expérience de terrain a été menée dans la ferme de recherche de KrishiVigyan Kendra, Gumla, pour évaluer les "effets des sources et des niveaux de silicium sur la fertilité du sol, le potentiel de production et la qualité du riz (Oryza sativa L.) sous le sol latéritique de Jharkhand" pendant la saison Kharif de 2017-18 et 2018-19. Les traitements comprenaient 3 doses de Si (50 kg, 100 kg, 150 kg Si ha-1) sous forme de silicate de calcium (T2 à T4), de cendres volantes (T5 à T7) et de paille de paddy (T8 à T10). L'expérience a été réalisée selon un plan aléatoire complet avec trois répétitions. On a constaté que la teneur en nutriments disponibles dans le sol augmentait avec des niveaux graduels d'application de Si. Les différentes sources de Si utilisées dans cette étude varient considérablement dans leurs propriétés physico-chimiques et leur comportement dans le sol. Parmi les paramètres chimiques (pH, EC, et C organique) et de fertilité (N, P, K, S, Mn, Zn, Fe, Cu, et Si disponibles).

  1. The basket is perfectly what I ordered and as listed. It came in the factory packaging and was perfect upon delivery. Thank you postal service lol. The delivery took way longer than listed though, it was listed to come in a week from purchase, but took a whole month. I had some concerns at first, but communication with the company was top notch and they were very professional and answered most of my questions satisfyingly. Just prepare for a longer wait than listed, but I got what I bought lol.

  2. Leaving positive feedback because 1) item was packed well & arrived as described 2) seller did give partial refund when subsequent price dropped below org purchase price. 3) communication was quick However, there was a downside to this transaction -item listed as in-stock but ended up waiting nearly a month for them to get it from their distributer then ship it to me (bought June 29th, arrived around July 21). Auction said 12-15 days. Better clarity would have prevented lot of frustration

  3. The seller was very responsive and answered me on a timely matter. The product itself came in its packaging and was new, not used at all. The packaging was not beat up or anything, safely delivered to my mailbox. No mix ups and zero stress with delivery. The price for the product is completely understandable for the product. I really appreciate the seller and I am very happy to have purchased through this seller. Completely trustable!
