apparatus for dosage of fertilizers in the irrigation water soluble solid

摘要

the present invention relates to a device particularly suitable for the assay of solid water-soluble fertilizers.it is used mainly in the fertirrigazione of herbaceous crops.the found is characterised by having a container for the solid manure with volumetric measuring element arranged above a tank containing water.the tub is preparing the solution fertilizer through the automatic manure dosage in amount desired.the apparatus is connected directly to the centrifugal pump for irrigation through a loading tube.applied on sent and with the pressure regulator, and an exhaust pipe connected to the suction of the centrifuge.its use offers considerable advantages to significantly reduce the cost per unit of fertilizer and to automate the doses of solid fertilizers used.
