Organic Versus Chemical Fertilizer
Adding to our series of ready to go science projects and educational materials, I would like to introduce a very interesting experiment. We would like to put our organic worm castings to the test. Worm Castings are much more nutrient dense than chemical fertilizers and top soil. Golf courses, commercial farms and even gardening hobbyists buy worm castings in bulk because they have been proven time and time again to beat even the best pesticide filled chemical fertilizers on the market.
This kit has two containers. One of them has worm castings and the other has a top brand of chemical fertilizer. Below, you can select which flower seed you wish to experiment with. All of them will sprout within a week under the right conditions. We include a care sheet, facts about our premium organic worm castings and a chart for you to track the growth of your plants in each container. It is a fun experiment and works wonderfully on a classroom windowsill or on the science fair table!
