The present patent application refers to a portable system for application and preferential dosage of fertilizers and pesticides comprising a joystick-type portable command for application of granulate particles by gravity flow, for applications located on the ground surface, vases with plants, etc. and for continuous applications (for example, grams per minute) inside plantation furrows or even in coverage of the total area. Manufactured for assembly with a discharge pipe, to be connected together to the bottom of a storage tank of granules, usually, a back equipment, for use by rural producers/creators in various applications, even in large areas, where, for example, an irregular topography of the ground prevent the access of tractor-implemented systems.
