True or false. plants are capable of using nitrogen directly from the atmosphere.

False, plants do not have this capability because nitrogen isn't reactive. Thus, the nitrogen, through the soil, is converted to nitrate by nitrogen-fixing bacteria. After the conversion, the plants are able to absorb it without an issue. However, it is not possible to "directly" absorb nitrogen itself. 

I hope I was able to satisfyingly answer your question. :)  

The answer is false plant cannot use nitrogen directly from the atmosphere
