Amino acids for fertirrigation
What is it? What is it for?


Apply 10-15 L/ha every 7-15 days by localized irrigation.

In the case of more frequent applications, divide the dose.

It can be applied with crop fertilization through localized irrigation or by soil injection. 

Time of application

It is recommended for use when the crop needs a physiological stimulus, such as:

  • Start of the vegetative cycle
  • Pre-flowering and setting
  • Development of vegetable organs for harvest

Its use is also recommended when the crop is exposed to unfavorable conditions (drought, cold temperatures, salinity, wind, root asphyxia, etc.) and in recovery treatments after critical periods (damage due to frost, hail, wind, etc.).
