“…Twenty minutes of grinding in a planetary mill and 60 min in a ring mill produced composites with a homogeneous microcrystalline mass with contents of 12.3% and 16.7% N 2 O 5 and 4.2% and 3.9% K 2 O, respectively, as well as impurities in the form of complex nutrients, namely P, S, Fe, Ca, and Mg. The presence of pyrite in composites synthesized quickly (5 min in a planetary mill or 15 min in a ring mill) indicates the integrity of the initial mineral structure of glauconite, which is characterized by the presence of sulfides [38].…”

“…In this study, for the first time, we investigated glauconite as an inhibitor for urea release. Glauconite is potassium phyllosilicate (clay mineral) with a dioctahedral structure [29][30][31][32] distributed in ancient marine sediments [33][34][35][36][37][38]. Due to the high content of K 2 O (up to 8-9%), glauconite can serve as an independent unconventional potash fertilizer [39][40][41][42][43][44][45] that has a prolonged effect [46].…”

“…Глауконит широко распространён среди верх немеловой осадочной последовательности Бакчар ского месторождения [22], и в отложениях гань кинской и славгородской свит его содержания до стигают 60 % [23,24]. В предыдущих работах ав торами были опубликованы данные с детальной структурно вещественной характеристикой этих пород [23][24][25][26], а также результаты практического их использования.…”

Глауконит -это глинистый ми нерал из группы диоктаэдрических слюд типа 2:1 (Т: О: Т) с дефицитом межслоя, который характе ризуется высоким содержанием калия (до 8 %) и отличается зеленой окраской и глобулярной фор мой [27][28][29][30][31].…”

“…The “evolved” variety of glauconite acquires high K 2 O content because of the prolonged interaction of the glauconitic substrate with seawater (10 5 –10 6 years) at the depositional surface (Amorosi et al, ; Banerjee, Bansal, Pande et al, ; Banerjee, Bansal, & Thorat, ; Banerjee, Jeevankumar, & Eriksson, ; Giresse & Wiewióra, ; Harris & Whiting, ; Hesselbo & Huggett, ; Huggett & Gale, ; Kelly & Webb, ; Odin & Matter, ). “Evolved” glauconites occur in close proximity to the maximum flooding surface as detrital sediment input is minimal corresponding to this important sequence stratigraphic element (Amorosi, ; Amorosi, ; Banerjee, Chattoraj, Saraswati, Dasgupta, Sarkar, & Bumby, ; Banerjee, Chattoraj, Saraswati, Dasgupta, & Sarkar, ; Bansal, Banerjee, Pande, Arora, & Meena, ; Rudmin, Banerjee, & Mazurov, ). The K/Ar and 40 Ar/ 39 Ar ages of authigenic glauconite constraints the age of sedimentary sequences in the absence of age diagnostic fossils (Bonhomme, ; Clauer, Liewig, Mossem, & Chaudhuri, ; Odin, ; Odin, ; Odin, ; Rathore, Prabhu, Vijan, Vic, & Misra, and many others).…”
