How to make liquid iron fertilizer and powdered iron fertilizer

Abstract

The journey of recycling iron from tomato, sardine, tuna, and harissa cans is a product renewal phase that will lead us to the agricultural future. Everything has a weight, and future weights are better for the beautiful, unhealthy environment. Unhealthy nature causes disaster for animals and humans, including exposure to epidemics, God forbid. This is what occupied my mind and thoughts about tomato cans, turning them into a new product life cycle through recycling iron. Iron isn't all recyclable; it's the tomato cans that cause harm to humans, especially children, while playing and having fun, and can cause injuries, God forbid, due to the rusting of the iron.
