Examples of nitrate

• The implications of restricting use of fertilizer nitrogen for the productivity of arable crops, their profitability and potential pollution by nitrate.

• It is doubtful, given the above chemistry, that any significant amount of nitrate formed in these solutions over the 4 d of testing.

• There may be ecological arguments that light and nitrate are the signals that initiate the germination process of perceptive (non-dormant) seeds.

• Wetlands may also act as pollution assimilation agents for nitrate pollution created by up-stream agriculture.

• Microbial immobilization of ammonium and nitrate in relation to ammonification and nitrification rates in organic and conventional cropping systems.

• Periodic testing showed no detectable nitrite concentrations, thus the results are reported as nitrate alone.

• Continents rising above sea level constitute the major renewable source of nutrients (nitrate, phosphate) essential to maintaining life.

• When necessary, the amplification products were further analysed on 6 % polyacrylamide gel stained with 0.1 % silver nitrate.
