You try all you can with soil improvement or better water management, if air is putrid, nothing will work.
Higher CO2 (or Higher O2 or higher NO) means disturbed Prana. Disturbed Prana means no ingestion, digestion, excretion. No excretion -> all sicknesses. So this is very critical for urban terrace farmers. They have worse air pollution to handle.
Agnihotra plays a vital role here. Doing homam in the vicinity of the land, with the use of Pure desi cow ghee, dung and other herbs produces balancing oxygen, NO and other gases. In short, it stabilizes Vayu and in turn Prana.
Planting more trees too will help. Peepal, Banyan and other fruit trees.
Cow dung microbial world also work hard for increasing Prana.
Presence of Desi Cow/Bull in the farm itself is sacred and self-saving.
Comment by Ranjit Kumar Dash
“Prana pervades all that we see on Earth; is impaired in neon-lit fume-soaked urban interruptions, which are but maiming mother nature. Terrace this, vermiculture that cannot make good what is getting damaged. Doom will eventually overtake all arty, smarty palliatives. Tatha na astu (May that never take place).”
Increased carbon dioxide levels in air restrict plants ability to absorb nutrients
The rapidly rising levels of carbon dioxide in the atmosphere affect plants’ absorption of nitrogen, which is the nutrient that restricts crop growth in most terrestrial ecosystems. Researchers at the University of Gothenburg have now revealed that the concentration of nitrogen in plants’ tissue is lower in air with high levels of carbon dioxide, regardless of whether or not the plants’ growth is stimulated. The study has been published in the journal Global Change Biology.
Researcher Johan Uddling has been working with Swedish and international colleagues to compile data on how raised levels of carbon dioxide impact on plant growth and nitrogen absorption.
