The crisis in energy and raw materials of mineral origin has drawn attention black to the problem of fertilizer savings, while giving it a new dimension. present circunstances no longer lend themselves to an over-generous approach which was so often practised in the recent past, and which sometimes continues to be today. It is therefore necessary to advance all reseach options enabling fertilizer consumption to be reduced in the future; it is already possible to make very substantial savings, thanks to careful management of plantation mineral nutrition. The corresponding methods are operational, based on the association between the experimental rigour of field experiments, and the flezibility of leaf analysis enquiries. Mineral nutrition must not be managed in function of general norms which have turned out to be eminently variable depending on the age of the cultures, the nature of the soil, and the climate and resulting potential. It is thus indispensable to turn to reference experiments set up in the heart of the industrial plantations. This is the only way of proving that a fertilizer is efficient, and of defining the critical levels to be used to draw up the specific fertilizer schedules for the region concerned. Critical nitrogen level drops with the age of the plantations. Phosphorus levels vary according to the level of nitrogen nutrition. The critical levels for potassium and magnesium depend on the nature of the soils, the climate and the production potential. |
