an efficient fertilization of fruit trees
Methods available to fertilization of fruit trees are not completely satisfactory. Ideally ,fertilizing must supply and maintain an optimal level of nutrients in the root zone during the growing season (Mengele & Kirkby,1979.Hig content of carbonates, compaction of soil and slow movement of nutrient in the soil reduce the availability of the nutrient in the deep zone where the roots of trees develops.
On the other hand, deeply use of both chemical and organic fertilizers for the root zone appears to be difficult. It could be possible to establish orchard base on canal fertilization (CF) to optimize both nutrient and water supplements to the plants……
