The Earth's soils are losing their nutrients because of things like flooding and overplanting. It may not seem like a big issue, but it is. This worsens already existing problems like world hunger. The lack of nutrients makes the soil produce fewer crops, therefore more people won't have food.
To address this problem, I have come up with an idea to help re-fertilize the Earth. Dropping it from above! By dropping it from above with a plane of sorts onto nutrient-lacking areas of soil, we wouldn't have to worry about spreading it ourselves. To test this theory, I decided to try airdropping a liquid fertilizer onto soil and see if it would safely land. For this experiment, I used a cup, balloons and liquid fertilizer. I poked holes to the in the cup, tied the balloons, and let it drop from an elevated area. The cup landed safely and tipped over its contents on to the soil.
I think this idea could help others because it could reduce the number of people suffering from hunger.
