    Notes: [Auszug] VARIOUS authors1'3-7 have published conflicting reports on the level of urea excretion in the urine of ruminants. Read1, investigating the urine nitrogen excretion of a pregnant female camel (Camelus bactrianus) fed on sorghum leaves, sweet potato and salt, reported that there was only a trace of ...

    Notes: [Auszug] The agreement between the calculated value for carbon mineralization after 250 treatments (73 per cent) and that found after 204 treatments (63-5 per cent) is satisfactory, particularly since the calculated value (based on the first 105 treatments) did not allow for the subsequent loss of structure ...

    Humus Decomposition in East African Soils (1956)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] Fig. 1 Fig. 2 As oxygen is consumed by the soil micro-organisms carbon dioxide is produced which is absorbed by the sodium hydroxide. This lowers the pressure in the respiration bottle so that sulphuric acid rises in the side-arm, makes contact with the anode and gererates oxygen. This diffuses ...

    Notes: [Auszug] For our investigations we employed the potassium trans salt prepared by Croft's method3 and purified by digesting in 1 per cent nitric acid (to destroy traces of potassium trioxalato chromiate) prior to recrystallization. The corresponding cis salt was prepared from the above by digesting 40 gm. ...
