InvestigationOpen accessEvery word in the titleComparative Ameliorative Efficiency of Phosphogypsum and Elemental Sulfur in Semi-Terrestrial Soda and Sulfate Moderately Halophytic Solonetz of the Light Gray Earth SubzoneKanaibek Kubenkulov, Nurzhamal Khokhanbaeva, Askhat NaushabayevThe article presents the data from field tests on determination of the relative ameliorative efficiency of equivalent dosages of phosphogypsum and elemental sulfur on the alkaline saline semi-terrestrialsolonetz. Basing on the analysis data of soil water extract, higher ameliorative efficiency of elemental sulfur compared to phosphogypsum and fast amelioration of alkali-saline soils with the use of sulfur have been detected. … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 6 Feb 2018 · 7,421 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNew Low-Temperature Technology of Producing Calcium Feed Phosphate with MicroelementsJózef HoffmannThe possibility of producing feed calcium phosphates in a way ensuring a low physical water content in the product was investigated in laboratory conditions. For this purpose the process use of a phosphoric acid solution with a higher (than in conventional methods) P2O5 content (53-63% by wt. P2O5) with CaO (molar fraction of 0.5-0.8) and CaCO3 in the phosphoric acid … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,739 accessesView PDF Cite
