In order to properly maintain a field, it is necessary to understand how many macro- and micronutrients a given crop species needs. Many years of research and experience showed the following demand of individual species for micronutrients:
Average total absorption of main yield + working yield (g/t)

Many nutrients are characterised by low mobility in the plant. In such situations, use foliar fertilisation in stages, and divide the dose of the micronutrient into 2–3 treatments. In this way, subsequent leaves are supplied with micronutrients with the development of the plant.
