The final sentence of this post, "Not just that, an innovation for the controlled release of the nutrients would be very essential", is the most important one. We need to find a way to improve food production without missing up with the ecosystem around.
I didn't know about options coming from nanoscience. That's cool (but I guess quantitative studies are still needed)!
I might not have known about it too if not for my colleague's research. The ideal situation would be to go organic 100% as this is the only way to maximise food production with minimal disruption to the ecosystem.
Unfortunately, the world is far from being ideal... We all know that at our age... :(
