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.
Claims24
A method for the fertirrigation of plants, comprising
- making available a series of mother solutions,
- 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,
- wherein the method further comprises
- an addition of iron and at least one polyphosphate to an aqueous phase with formation of at least one iron solution and at least one polyphosphate at a pH of between 4.5 and 6.2.
