fertilizer
Liquid
fertilizers permit direct application on the leaves of the plants,
thus shortening the usual way from the root or the bulb to the leave.
According to practical experience, the application of trace nutrient
fertilizers with a large percentage of calcium together with each
fungicide or insecticide spraying can be recommended. A supplement
of 2 - 3 lt/ ha has proven to be the best quantity.
