One of the most promising challenges for modern sustainable agriculture is how to decrease the
high unnecessary fertilization rates without negatively influencing the nutritional requirements
of plants, and decreasing crop yields and plant products quality.
Indeed, the knowledge of soil allow us, not only to choose culture, rootstock and fertilize
according to the international standards but also to save money on fertilizers and water on
irrigation.
Fertilizers applications to fruits are made to supplement plant nutrient elements naturally
occurring in the soil in order to maintain an optimum supply in the rooting zone. Application
of fertilizers, except for this purpose, is wasteful and may have deleterious effects on both the
crop and the environment. Improperly applied nutrients may cause excessive growth, or create
nutrient imbalances, which can greatly complicate management practices.
All fruit crops do not have the same nutritional requirements. Further, the fertilizer program in
a given fruit planting may need to be varied from year to year and location to location. These
conditions make it necessary for a grower to determine the fertilizer needs of a given planting
on an annual or seasonal basis
