Hello! My Biology Class assigned us to create a lab experiment with plants.  My 
experiment will have soil as the variable.  I will have 3 pots, one pot with 
just regular soil, another pot of soil without nitrogen (I'm going to burn off 
the nitrates and wash it out), and the last pot containing nitrogen-enriched 
soil.  So I was just wondering how I can regulate the amount of nitrogen I can 
put into the third pot of soil?  Thanks~!
