Lab Feb. 22

This week in lab, we discussed the soil test report and how to determine the area of an irregular shaped plot. Each group measured the size of their prospective sites, and calculated lime and fertilizer applications based on recommendations similar to those in the soil report.

I realize that some student were frustrated with the multiple conversions and calculations required to determine the proper rates, but a little practice is all that is required. What I would mostly like for you to take away from the lab is how to calculate the area of a plot and how the test report recommendations are related to that area. You should be aware of the N-P-K number on fertilizer products and appreciate the difference between pounds of fertilizer and pounds of each mineral contained within.

For the lab report this week, make sure to describe how you determined the area of your space and the results of all calculations.
