tannery based foliar fertilizer for coffee production

摘要

foliar fertilizer based on tannery sludge for coffee production. The present invention relates to the creation of a nutrient solution by diluting the tannery sludge in water in different proportions, serving as foliar fertilizer. such a process of leaf fertilization in seedlings, refers to a process never before used to produce conilon coffee seedlings. This new seedling production process has the advantage of being able to replace the foliar fertilization in conilon coffee seedlings made by conventional chemical fertilization by the liquid tannery sludge, since this residue has many essential elements for plant development, with potential for replacement of commercial chemical fertilizers at low costs.
