Abstract By integrating various irrigation and agriculture management techniques, it is possible to considerably improve water productivity. In order examine the impact of scheduling (1.0 1.2 pan evaporation coefficient), planting method (ridge raised bed), potassium silicate foliar application (0 ppm 100 ppm) on maize ( Zea mays L) growth, yield, water-related factors, a two-season field exper...

Abstract The purpose of the work was to analyze first stage UE “Dekhkanabad plant potassium fertilizers” find out reasons for decrease in efficiency process desliming sylvinite ore Tyubegatan deposit. It has been established that is due a content chloride and an increase insoluble residue ore, proportion weakly sludge carbonate sulfate minerals residue, compared with silicate minerals, differen...

-Intercalation complexes of a Hungarian kaolinite were prepared with hydrazine and potassium acetate. The thermal behavior and decomposition of the kaolinite-potassium acetate complex was studied by simultaneous TA-EGA, XRD, and FTIR methods. The intercalation complex is stable up to 300"C, and decomposition takes place in two stages after melting of potassium acetate intercalated in the interl...

The present work evaluated the effect of soil (S) and foliage (F) applied potassium on growth, yield, quality potato plants. Potassium was added in at recommended rate for all treatments combining mineral fertilizers with K-feldspar biofertilizers, while foliar spraying included application citrate (PC), silicate (PS), monopotassium phosphate (MP). obtained results showed that plant height high...

Interfacial reaction between quartz and potassium silicate glass was studied at both 900 °C 1000 °C. The results showed that no phase transformation observed for the pure or Instead, particles in K2O-SiO2 glass, from to cristobalite occurred quartz/glass interface first, then crystals transformed into tridymite. tridymite formed became site of heterogeneous nucleation, which induces plenty prec...

Hydrothermally grown crystals of alpha-K3NdSi6O15 x 2H2O, potassium neodymium silicate, have been studied by single-crystal X-ray methods. The compound crystallizes in space group Pbam, contains four formula units per unit cell and has lattice constants a = 16.008 (2), b = 15.004 (2) and c = 7.2794 (7) A, giving a calculated density of 2.683 Mg m(-3). Refinement was carried out with 2161 indepe...
