High nitrate concentration in groundwater is a major problem in agricultural areas in Iran. Nitrate pollution in groundwater of the particular regions in Isfahan province of Iran has been investigated...
Nitrate nitrogen (NO3-N) concentrations of stream water have been observed in the headwater catchments within Gunma Prefecture located in northwest of Metropolitan area Japan. Large differences of NO3...
The effects of light intensity and altered red (R)/far-red (FR) photon flux ratio on nitrate concentration and nitrate reductase (NR) activity in komatsuna (Brassica campestris L. cv. ‘Harumi komatsun...
Spinach plants (Spinacia oleracea L.) were grown in a greenhouse using fertigation based on cumulative solar radiation, and effects on plant growth, nitrate concentration in the leaves, and nitrate ut...
This study confirmed the usefulness of fertigation based on cumulative solar radiation in order to establish a fertigation technique that would decrease the nitrate concentration in spinach leaves (Sp...
Komatsuna Natsurakuten’ was cultivated during three successive crop seasons (early summer, late summer, autumn) in the same soil consisted of andisols in a greenhouse. Four fertilization formulae wer...
At a regional scale, high nitrate (NO3‾) concentrations in upland surface waters generally occur in tandem with high nitrogen (N) deposition levels. However, significant differences in the patte...
In catchments with impervious bedrock, the nitrate concentrations in streamwater often show marked seasonal and small inter-annual variations. The inter-annual trends are usually attributed to changes...
The hydrological and biogeochemical monitoring of catchments has become a common approach for studying the effect of the evolution of agricultural practices on water resources. In numerous studies, t...
