Studies on the restoration of permeability to water of soils previously rendered impermeable by sodium carbonate


, : Studies on the restoration of permeability to water of soils previously rendered impermeable by sodium carbonate. Mysore Journal of Agricultural Sciences 6(4): 503-505

In laboratory experiments salts increased the rate of capillary rise in columns of black clay soil in the order: NH4Cl > NH4NO3 > BaCl2 = CaCl2 NH4Br > (NH4)2SO4 > (NH4)2HPO4.

The hitherto unknown female of T. sola was recently discovered in N.-Tyrol, near Imst, in pitfalls placed at a xerothermic slope with pines in 900 m a.s.l. It differs from its congener T. minutissima (O.P.-CAMBRIDGE, 1879) in sternum, which is poi...

The water-holding capacity (WHC) of post-mortem porcine musculature is an important quality trait, and it is desirable for the industry to assess its variations for purposes of evaluating and processing pork products. There are several procedures...
