Abstract The term“zeolite” was created by Cronstedt (1756, for mineral which expel water when heated and hence seemto boil. They are very common and well known as fine crystals of hydrothermal genesis in geodes and fissures of eruptive rocks, or as microcrystalline masses of sedimentary origin. A natural zeolite is a framework alumina-silicate whose structure … Continua a leggere Zeolites as additives for the rooting of Camellia japonica and Proteaceae Juss
Abstract Zeolites are crystalline, hydrated aluminosilicates of alkali and earth metals that possess infinite, three dimensional crystal structures. They are further characterized by an ability to lose and gain water reversibly and to exchange some of their constituent elements without major change of structure. Zeolites were discovered in 1756 by Freiherr Axel Fredrick Cronstedt, a … Continua a leggere Germination Of Vegetable And Grassland species With Micronized chabazitic-Zeolites And Endophytic Fungi.
Nel 1909 il chimico tedesco Fritz Haber riuscì a trasformare l’azoto gassoso, abbondante nell’atmosfera ma non reattivo, in ammoniaca (azoto reattivo). Vent’anni più tardi, Carl Bosch sviluppò un metodo per sfruttare a livello industriale l’idea di Haber. Nei decenni successivi, un numero crescente di industrie cominciò a trasformare tonnellate di ammoniaca industriale in fertilizzanti di … Continua a leggere Contributo delle Zeolititi nella mitigazione delle problematiche ambientali conseguenti alle vigenti pratiche agricole, alla gestione dei reflui zootecnici ed in floricoltura
AbstrAct:D. Prisa, Italian chabazitic-zeolitite and Effective Microorganisms for the qualitative improvement of olive trees. Natural Zeolites are a mineral family composed by 54 different species chemically defined as “hydrated allumino-silicates of alkaline and alkaline earth elements” and structurally belonging to the tectosilicates. Due to their crystal chemistry, zeolites show physical-chemical peculiarities such as high and … Continua a leggere ITALIAN CHABAZITIC-ZEOLITITE AND EFFECTIVE MICROORGANISM SFOR THE QUALITATIVE IMPROVEMENT OF OLIVE TREES
With the aim of improving the growth of plants of Aloe barbadensis and A. arborescens and improve the content of sugars and minerals, several experiments were conducted replacing chabazitic-zeolites with normal inorganic substrates and adding the effective microorganisms (EM) to assess whether they affected plant development. The experiment on both Aloe species involved three treatments: … Continua a leggere Effect of chabazitic-zeolites and effective microorganisms on growth and chemical composition of Aloe barbadensis Miller and Aloe arborescens Miller
Abstract In order to improve the growth of Impatiens and Oleander plants, several experiments were conducted in which chabazitic- zeolites were added to cultivation substrates to assess their influence on plant growth and reduction of fertilizer use. The experiment on Impatiens and Oleander involved 4 treatments: control with total fertilization; control with reduced fertilization; substrate … Continua a leggere Improvement quality of impatiens and oleander plants with chabazitic-zeolites
