Hi Jonathan,
Thank you for your reply.

The soil in our area is calcareous medium black clayey soils.
I am also very concerned about water quality that is why I am doing whatever I can afford to start with (Structured water). RO, I will see if I can convince my father :(. He does not believe that we can get profit out of this land to cover all the costs in a year. anyways, I will give it a try.

for foliar, I will have to see if there are any good products like AEA in India. otherwise, I will need to make my own nutrient applications.
