Research Sites
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.
pH Results

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
