How will you determine cost effectiveness? What is the percent of difference in cost and, I'm assuming bean production, that would be significant to the point of choosing one feritilizer(or no fertilizer) over another?
How are you measuring damage to the environment when you are planting the beans in test beds? Will you chemically test the soil? How will this be an accurate indication of the effects of a complex ecosystem?
Good incorporation of peer-reviewed sources.
How ae you going to measure color of the plants?
What are the criteria for ranking the plants health? A.k.a. what conditions rate a 1 and what conditions rate a 7 and all the numbers in between? Will there be an analysis of the data with standard deviations used to assign such and such height through such and such height to different health number categories?
When will the experiment be complete? After four weeks? When the beans get to a certain height?
