Not running out of phosphorus per se, but instead losing it to places that it is difficult to recover (groundwater and the ocean). We never run out of phosphorus as mass can neither be created or destroyed, just translocated or changed in form.
There is a cost associated with nitrogen fixing and the plant supplies sugars and other nutrients to the bacteria that does the fixing. There is no free lunch. In fact, it would reduce the carbohydrate yield potential of plants. The conversion of 1 mole nitrogen to 2 mole ammonia requires 25 mole ATP, i.e. the fixation of 1 gram nitrogen costs 10 g glucose - under favorable conditions. In some bacteria, nitrogen is very pricey, such as the Azotobacter where it needs 100 gram of glucose just to fix 1 gram of nitrogen. If you supplied the nitrogen fertilizer, you would have increased the yield by 50 gram glucose for each gram nitrogen fertilizer added at 50% efficiency.
Plants can not grow without the fixed nitrogen though. Bringing a plant evereything it needs while defending it will always produce the highest yealds. This techknolagy would be monumentel in a place where inputs are unavalibel or expensive and the way thay inoculate the seed would allow it to be used on hardened varitys of grains. Used on tropical corn that also has traces of nirtogen fixing bacteria on its arial root tips coupled with long groth cycles of tropical corn could be verey useful in the tropics where volcanic soil is high in minirals but low in nitrogen. I can't wait to see this as a cheep massproduced easey to use consomer product. lol
So whatever happened to this?
Wonderful research, we gona try to see the results if are similar in different environments...but congratulations and all the best for the team
Yo Nottingham nerds do you have a follow up video of this. Been 10 years any improvement

from what Ive heard we are running out of phosphorus not nitrogen...
fantastic,healty living seems to get better,in world times all people want change.

+Joe Real can you explain me more about nitrogen fixation bacteria pls?

Nice
