Nitrate vulnerable zones (NVZs) are areas designated as impacted, or at risk of impacts, by agricultural nitrates applied as fertilisers to boost crop yields.In the past, the process of designating an area as a NVZ has been perceived to be reliant on a limited amount of data and lacking in transparency.itrate vulnerable zones (NVZs) are areas designated as impacted, or at risk of impacts, by agricultural nitrates applied as fertilisers to boost crop yields.
Volatilisation of nitrogen from CAN is negligible, therefore the timing of the applications is flexible. Calcium Ammonium Nitrate can be considered as near-neutral in its effect on soil pH-and therefore can be used on soils that have a low pH without lowering further.This also means it is most suitable for using on perennial fruit crops (where soil incorporation of lime is normally difficult to achieve). âCan be considered as near-neutral in its effect on soil pH. 2  For use on perennial fruit crops (where soil incorporation of lime is difficult). 3  Contains equal parts of fast acting nitrate-nitrogen and longer lasting ammonium-nitrogen.
