摘要
Four com. mineral fertilizers (Polifoska (R) Tytan, Polidap (R), Salmag and Saletrzak 27 Standard) were analyzed for granulometric compn. SGN (size guide no.), UI (uniformity index), and GSI (granulometric spread index) were calculated. In addn., 4 addnl. coeffs. detg. the dispersion, variability, asymmetry and flattening of the grain size were described and detd. On this basis, the examined fertilizers were characterized and their granulometric compns. were compared.
