is ammonium nitrate netural
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). âCan 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.
