Abstract
A brief review of nutrition and fertilization of processing tomato is presented.
Datas are given about nutrient requirements and mineral absorption rhythms which are highest during flowering and fruit setting especially for machine harvested cultivars.
Main nutrient specificities towards production quantity or quality are recalled.
Fertilization must be reasoned according to crop demand and soil availability for a definite production objective which may be different from maximum yield and have to be combined with other aims such as unwasting of resources and minimum pollution of the environment.
This leads to try to improve fertilization efficiency.
Fertilizer placement is a possibility which is illustrated here by research results, trickle fertigation is another way but it is not still possible to adopt it anywhere.
Further progress is expected from basic research on nutrient dynamics in soil but also from modeling and simulating field crop functioning and from using genetic variability too.
Anyway research must go on helping producers to fertilize in a reasoned and responsible way.
