The first thing we did was take soil and worm samples from three different sites. The sites were the Grant High School garden, Ella’s home garden, and MLK’s community garden.

Ella’s Family Garden has more worms than the other gardens because her father adds an abundance of leaves to it. The leaves supply food(organic matter & carbon) for the worms and provides shade for them to live.

Grant’s nitrogen levels were considerably high because there were Fava beans planted in that area. Fava beans provide the soil with nitrogen.

The other gardens levels were low because they probably didn’t do anything to increase the nitrogen levels, like plant beans or add fertilizer.

Ella’s Family garden is significantly below our expected standards. This might have had been caused from an overdose of leaves. Over time too much organic matter causes the soil to be very acidic.

Grant’s and MLK’s levels were in the best range for growing most vegetables and flowers
