Which fertilizers are possible test subjects?

Question

My group's investigative project is about organic fertilizers on plants. I'd like to know more about possible fertilizers we can test and the kind of plant we could test it on.

Answer 1

As far as what type of plant to use, use something that grows and matures fast.  Some options are Brassica rapa, sunflowers, corn, or wheat.

As far as fertilizer type, will you have money to buy some?  If you have time, you could try composting some fruit/veggies or creating your own organic mixture.
