Remediation Process

To remediate our soil we looked at our results from the fertility analysis. Because our soil seemed to have fairly high levels of necessary nutrients, we felt that we didn't need to add very much to fix it. This is likely because that although we could not see any microorganisms in the berlese funnel test, there were many other organisms such as worms that naturally fertilize the soil. This could also be due to the percent organic matter that we found to be about 27%, our soil was naturally a good source of nutrients. The pH was a little over 7 which is roughly the ideal level needed to grow lettuce, so we did not change it. We filed the cup with 67 grams of soil (same as control). Then, we measured 1.9 grams of inorganic soil in proportion with the amount of soil. Next, we added 9.7 grams of organic manure fertilizer. We planted 5 lettuce seeds and watered them both the same amount. We expected that these extra nutrients provided by the fertilizers would result in healthier lettuce plants that grow large and faster than the control soil.
