When I was young before I came to the US my father explained how different foods grow in farms in Bulgaria.
I asked him "What if instead of all the work a farmer does to make food better by going around with different sprays and nutrients he were to put them in the water that pipes carry to water the plants. By mixing it in he saves time and energy to walk through the field. He could easily use machinery but that uses gasoline. All he has to do is let the pipes work for him.
The plant only takes in what it needs and the soil takes the rest of things. He could even create (with time this was the 90s) liquids that are like fertilizer and feed the soil with nutrients before each season when the plants start to grow.
He liked to speak to many people at a Bulgarian Church in New York and he had a great memory. He may have told all of them and he may have not spoken about anything but I thought I would write it. For a few weeks before I moved on I actually wanted to be a farmer. To grow more food for everyone in Bulgaria so that all of us can eat by doing this. Mixing everything needed to help grow food in the water carried to the plants because a pump is very strong and doesn't use much electricity or gasoline.
And we've learned from past things. (Previously we spoke about water and how much money it costs for electricity to cool water in the summer compared to a fan or air conditioner.)
P.S. I have eyesight problems. Hopefully no one edits this. I was thinking I would talk about it with my peer counselor some day.
