BRS 810), it was observed that the inoculation of rhizobia UFRGS Om57, serradella isolated, induced increase in shoot dry mass, being equivalent to that produced in non-inoculated plants and receiving addition of nitrogen equivalent
to 100 kg of N ha-1 (NI 100 Control) and surpassing all other treatments (Table 1).
The addition of urea at 0.5% level to a low protein basal diet (14% nitrogen equivalent
) had not been shown to exert any significant influence on weight gain of bulls (Rakhimov et al., 1984).
Where: RE (%) = Relative Efficiency index; DM Inoculated = total dry mass of plants from the inoculated treatment with the addition of nitrogen equivalent
to 50 kg de N ha-1; DM Control NI 50 = total dry mass of plants from non-inoculated treatment with the addition of nitrogen equivalent
to 50 kg de N ha-1; DM Control NI 100 = total dry mass of plants from non-inoculated treatment with the addition of nitrogen equivalent
to 100 kg de N ha-1.
This equates to 2,792 tons of nitrogen equivalent
10-10-10 fertilizer legally dumped into the Cape Fear River.
It maintained that this would enable dairy farmers to continue managing all cattle manure on their farms, even if the corresponding nitrogen equivalents
run slightly over the authorised 170 kg/hectare.
