We have been very busy during the last week with our rooftop crops, harvesting, weighing and recording data. Thanks to the volunteers who have helped us out (Erin, Daryl, Laura, Megan, Frank, Ana, Tim and Jon) we have successfully harvested all of our radishes and obtained a lot of data.
The methods we used were as follows: (Each pot had 3 radishes in it)
- Remove the soil from the pot and using a bucket of water, separated each radish (attempting to keep the roots intact).
- Photograph the radishes with I.D tag
- Number radishes/leaves from each pot 1, 2, or 3
- Measure root length, bulb (height and width), and leaf (height and width)
- Weigh radish bulb
- Weigh radish leaves
- Dry the radish/leaves and weigh again
After labeling each radish and it's leaves with a number 1-3 we put them into a paper bag labeled with their I.D (an I.D. for example might read R-GG-1 meaning 'radish-Gaia Green- replicate 1'). We weighed them immediately after harvest as well as 5 or 6 days later after they had dried out. This is to account for any variation in mass due to water retention.
Now the fun part... analyzing all the numbers!
While we are doing that we will soon be starting to harvest the next crop... kale.
We noticed visually that there were increases in size of radish between the control (no amendment) and the ones grown with amendments. Not surprisingly the Miracle Grow radishes were quite a bit larger but we noticed that radishes grown in Gaia Green also did very well and seemed to have healthier, larger foliage.
We will look at the trends that the data tells us to get a better idea and know for sure what the differences are.. stay tuned!
