Relative to the standard simulation, the NITR3 produces significantly higher rate of nitrate uptake (0.97 mmol N m−2 d−1), but lower rate of ammonium uptake (0.99 mmol N m−2 d−1).
Also, Tong et al. (1997) reported higher rate of nitrate nitrogen leaching which polluted underground water particularly with the continuous use of chemical fertilizers compared to the organic fertilizers.
Younger roots have been shown to have higher rates of nitrate uptake and higher tissue N concentrations (Volder et al. 2005); however, the proportional change in average root age may not have been large enough to affect the average tissue N concentration in our bulk samples.
They were reported that in some cases acid mine drainage (AMD) of coal tailing dams had a high rate of sulfates, nitrates, chlorides and heavy metals which were above the average that specified by the World Organization of Health (WHO) (Battioui 2013).
The previously high rate of emigration declined.
"Our results confirmed our initial suspicions in that we found relatively high removal rates of nitrate from stream water in most streams," says aquatic ecologist Patrick Mulholland of Oak Ridge National Laboratory in Tennessee.
High rates of OM deposition may also stimulate microbial activity leading to sediment anoxia and, consequently, nitrate uptake (denitrification) and carbon burial [40], [41].
high rates of home ownership.
Maniema province records high rates of malnutrition.
The electrical migration enables faster transport of calcium ions, whilst application of ammonium nitrate as catholyte enables higher rate of dissolution of calcium hydroxides.
