In plants, potassium and nitrogen are the two elements required in greatest amounts, while in animals and humans potassium is the third most abundant element, after calcium and phosphorus. Without sufficient plant and animal intake of potassium, life as we know it would cease. Human and other animals atop the food chain depend upon plants for much of their nutritional needs. Many soils lack sufficient quantities of available potassium for satisfactory yield and quality of crops. For this reason available soil potassium levels are commonly supplemented by potash fertilization to improve the potassium nutrition of plants, particularly for sustaining production of high yielding crop species and varieties in modern agricultural systems.

Jiménez-Espejo1,4, Stefano Lugli5, Vinicio Manzi6, Marco Roveri6, Hodaka Kawahata2 and Naohiko Ohkouchi1 Abstract The evaporites of the Realmonte salt mine (Sicily, Italy) are important archives recording the most extreme conditions of the Messinian Salinity Crisis (MSC). However, geochemical approach on these evaporitic sequences is scarce and little is known on the response of the biological community to drastically elevating salinity. In the present work, we investigated the depositional environments and the biological community of the shale–anhydrite–halite triplets and the K–Mg salt layer deposited during the peak of the MSC. Both hopanes and steranes are detected in the shale–anhydrite–halite triplets, suggesting the presence of eukaryotes and bacteria throughout their deposition. The K–Mg salt layer is composed of primary halites, diagenetic leonite, and primary and/or secondary kainite, which are interpreted to have precipitated from density-stratified water column with the halite-precipitating brine at the surface and the brine- precipitating K–Mg salts at the bottom. The presence of hopanes and a trace amount of steranes implicates that eukaryotes and bacteria were able to survive in the surface halite-precipitating brine even during the most extreme condition of the MSC.

Bell ABSTRACT Experimental logging of holes drilled through potash deposits in the Carlsbad district, southeastern Hew Mexico, demonstrate the consider­ able utility of gamma-ray, neutron, and electrical resistivity logging in the search for and identification of mineable deposits of sylvite and langbeinite. Such deposits are strongly radioactive with both gamma-ray and neutron well logging. Their radioactivity serves to distinguish them from clay stone, sandstone, and polyhalite beds and from potash deposits containing carnallite, leonite, and kainite.

Stephanyk 57, Shevchenko str., 76025 Ivano-Frankivsk, Ukraine 2State Enterprise Scientific-Research Gallurgi Institute 5a, Fabrychna str., 77300 Kalush, Ukraine Abstract The hydration of soluble Langbeinite and kieserite was investigated in the presence of potassium chloride and sodium sulfate. The addition of sodium sulfate affects water activity less than in the case of clean water. Therefore, we have conducted a research by adding water instead of schoenite solution. According to the results, hydration of Langbeinite by adding sodium sulfate in the first 240 hours occurs more intensively than without sodium sulfate with formation of a readily soluble schoenite and halite. Keywords: Langbeinite; Kieserite; Conversion ; Sodium sulfate; residue of hardly soluble langbeinite, kieserite and polyhalite, its drying Schoenite solution with obtaining potassium-magnesium concentrate, containing K2O - 20,4%, MgO – 16,0% and Cl - less than 1%. The solution after the Introduction stage of dissolution of ore is illuminated, evaporated, separated at first sodium chloride and then schoenite [5]. The polymineral potassium-magnesium ores contain both readily soluble minerals: kainite (KCl·MgSO4·3H2O), sylvite (KCl), halite During processing of kieserite hartzalts of Germany, containing (NaCl) as well as hardly soluble: langbeinite (K2SO4·2MgSO4), polyhalite 17-28% of kieserite, crushed ore is subjected to hot dissolution (K2SO4·MgSO4·2СаSO4·2H2O), kieserite (MgSO4·H2O).

No. : 15 /569 , 207 sulphate (MgSO4 ) and potassium sulphate ( K ,S02 ) so as to convert the kainite into leonite (K2SO4 .MgSO4 . 4H20 ) ; (22 ) PCT Filed : May 4 , 2016 optionally contacting the leonite with water to remove excess MgSO4; and contacting the leonite with water so as ( 86 ) PCT No. : PCT /EP2016 / 059952 to leach the MgSO4, contained in the leonite , and to at least $ 371 (c )( 1 ), substantially selectively precipitate potassium sulphate ( 2 ) Date : Oct. 25 , 2017 (K2SO4 ) . The method according to the invention can be operated at higher temperatures , in particular at tempera ( 30 ) Foreign Application Priority Data tures above 35° C .
