Optimizing the Usage of Fertilizer

Jessica Shen

With the increasing demand for beautiful lawns in front of our houses, more and more people are using chemical fertilizers. The optimized system takes a bag of fertilizer that can be simply attached to the spreader. This requires no pouring or measuring. The spreader has four parts: The bag, tester, weight feedback, and drop spreader itself. As the user walks, the spreader tells the user how much they have used vs how much they should have used, letting the user know the perfect amount to use.
