When applying nutrients, the type of fertiliser and the application technology are of great importance, but timing should not be disregarded, either.
The biggest risk is applying fertiliser at a time when there are no living plants in the area.
Such cases include large amounts of nitrogen fertiliser applied and worked in before sowing, or applied by the seed drill alongside the row, which might be washed in by a heavy rainfall so deep that the roots of your crop can no longer reach it.
It is better to apply a quick-absorption liquid fertiliser when the plants are able to use it.
The total amount you want to apply should be divided into several parts to minimise the risk.
The first dose – in the case of maize – should be injected next to the row when the plants have 8 leaves, and the second dose when the tractor can just about enter the crop field without damaging the crop.
The injected liquid fertiliser will start to have a positive effect within a few days even if there is no rain, which is guaranteed to show on your plants.
