We predicted that a reduction of MgSo4 in our experimental recipe would not only be cheaper but be as effective as PLANT-GRO is with plant growth, leaf development and weight or mass for the species Zea mays and Phaseolus vulgaris. Our results did not support our prediction due to the noticeable difference in leaf development, height growth and average weight or mass difference according to recipe. The PLANT-GRO recipe was larger in all categories than the Experimental recipe for both species of plants. By decreasing the Magnesium Sulfate (MgSO4) from the PLANT-GRO recipe for the Experimental recipe, the plant had a decreased amount of Magnesium and Sulfur. The Experimental recipe had removed too much MgSO4, for the plants given the Experimental recipe showed signs of Magnesium and Sulfur deficiencies. Magnesium deficiencies are expressed in a decreased amount of leaves and chlorosis, since Magnesium is used in photosynthesis. Sulfur affects the protein structures in the cells, so deficiencies are expressed in a considerable reduction in plant growth and weight. These deficiencies lowered the average leaf count, stalk height, and weight for those plants given the Experimental Recipe.
Magnesium and Sulfur are nutrients that greatly affect the size of plant growth. By drastically reducing the amount of Magnesium Sulfate in the Experimental recipe compared to the PLANT-GRO recipe, big deficiencies occurred. To increase plant growth, the Magnesium Sulfate should not be decreased in the class recipe. However, it would be beneficial to observe the color of the leaves and the length of the roots for each species of plants as well as the stalk height, leaf count, and dry mass. This will show the health of the plant and narrow down nutrient deficiencies better in order to make a better class recipe.
