The limited availability and input
of nitrogen, the
application of mechanical and thermal weed control and more diverse crop rotations and a higher crop diversity lead to more favourable conditions for many wild plant species.

of invasive species; and engineered seeds and plants destined for distribution to the public.
Their findings have been recently published in EPJ D and are particularly relevant for the development
of novel
applications in medicine, health care and materials processing because they involve air at normal atmospheric pressure, which would make it cheaper than
applications in inert gases or
nitrogen.

applications in developing and / or tropical countries, where present use
of nitrogen fertilizers is, in many cases, relatively inefficient (e.g., rice production).
One possible
application could be in zero tillage systems, where coated
nitrogen fertilizer might allow considerably higher rates
of fertilizer to be applied close to the seed.
About 91 %
of farmers are practicing the technology at different levels depending on the component adopted out
