Hi!
I am writing to ask you until when before harvesting a vegetable or fruit can foliar sprays or fertigation be applied? The question is to avoid eating nitrates or substances that are not highly digestible for us humans.
I am also asking if the answer to the above question also applies to dry pelleted manure dissolved in water with the right dilutions given as a foliar spray or in fertigation.
Thank you for your helpfulness!
All the best!
