30/11/2012 · An assessment of the impact and magnitude of nitrate leaching from agricultural activities is necessary in order to design and implement appropriate regulatory These concerns about groundwater nitrate contamination have led to the following research Both processes could thus reduce leaching of nitrates into groundwater.
Nitrogen Leaching Risk Assessment • Used to assess each field’s potential for nitrates to leach out of the plant root zone and into tile flow or to groundwater. • Nitrogen Leaching Risk Assessment Procedure found in Section 1, FOTG. • Nitrogen leaching potential is determined by combining and groundwater concentration will tend to approach steady state - To address local MS and EU-wide questions estimates of leaching potential in vulnerable areas study design must be statistically rigorous • Syngenta wish to determine 90th centile concentration of polar herbicide metabolite beneath treated maize fields with defined certainty
