Comparison of the Machigin and CAL Methods for Extraction of Plant Available P in Soils

Nurzat TOTUBAYEVA

Fertilizer recommendations for phosphorus (P) are generally based on the soil content of plant available P and the amount of P exported by the harvested crop. In countries of the former Soviet Union (SU), a widespread method is the Machigin extraction. The relationships between soil P contents extracted with this and other European methods are not well established. Here, we compare the Machigin soil P extraction method with the Calcium Ammonium Lactate P(CAL) procedure that is commonly used in Central Europe. Both methods were tested with 94 soil samples originating from Kyrgyzstan, Ukraine, a ...Более

Nutritional composition of ghee of various animal origins produced in some silk road countries

Canıl İSKAKOVA

This study aimed to investigate the fatty acids, vitamins, and minerals of ghee from various animal milk from different countries, such as India, Kazakhstan, Kyrgyzstan, Mongolia, and Turkey. Ghee consists of 98.9 of fat, irrespective of the animal source. Among the short- and medium-chain saturated fatty acids, all samples contain butyric (C4:0), caproic (C6:0), caprylic (C8:0), and capric acid (C10:0). Mare and goat ghee additionally contain undecanoic acid (C11:0). Major fatty acids were myristic acid (C14:0), palmitic acid (C16:0), stearic acid (C18:0), and monounsaturated fatty acid was o ...Более

Phosphorous removal from anaerobically digested municipal sludge centrate by an electrocoagulation reactor using metal (Al, Fe and Al-Fe) scrap anodes

Mehmet KOBYA

Phosphates are a major cause of eutrophication and growth of algal blooms in surface waters. The current study investigated phosphorus removal from sludge centrate effluent (SCE) of a municipal wastewater plant by packed-bed electrocoagulation (EC) reactor. Distinctively, iron (Fe), aluminum (Al) and Al-Fe hybrid scrap anodes were used. The influence of initial pHi, applied current and packed anode bed density were evaluated. Phosphorous removal efficiency of 99.99 ?as obtained at applied current of 0.20A with anode bed densities of 0.18 kg Al/m3 (pHi 5.0) and 0.48 kg Fe/m3(pHi 7.0). Optimum o ...Более
