Abstract
Plant fertirrigation method comprising the formation of a series of mother solutions, the feeding of each of the mother solutions into a dilution system in order to form a fertirrigation solution, the supply to a fertirrigation device by means of a transfer device, supplying said fertirrigation device with said fertirrigation solution, and an addition of iron and of at least one polyphosphate.
Claims16
A method for the fertirrigation of plants, comprising
- making available a series of mother solutions comprising at least one mother solution comprising iron and at least one polyphosphate at a basic pH or at a pH of between 4.5 and 6.2, having a concentration of iron of 0.15 mM to 500 mM and formed by adding iron and at least one polyphosphate to an aqueous phase,
- feeding each of the mother solutions into a dilution system, in order to form a fertirrigation solution, and
- supplying a fertirrigation device by means of a transfer device, and supplying said fertirrigation device with said fertirrigation solution,
- with the proviso that if said mother solution is at a basic pH, a sufficient quantity of acid is added in said dilution system prior to feeding said mother solution and sufficiently intensive mixing conditions are provided at a feed point of said mother solution in said dilution system so that said fertirrigation solution has a pH below 6.2.
