Reaction to Chapter 5 and 6

The quote at the beginning of the chapter reminded me about an idea that I had for part of our answer to "Why aquapomics?" "The soils are not being replenished and the land is dying." When soil farming is done properly, crops are rotated to allow for nutrients to replenish. With an aquaponics system, one would not have to worry about crop rotation. Reading the rest of the chapter taught me that the environment needed for growing is very particular. A lot of considerations need to be taken before making a decision. The main factor is temperature required for optimal bacteria growth. This factor helps determine where your system is placed. There are many inside considerations including weight, humidity, water spillage, light, and sound. These particular factors raised red flags in my mind knowing our test system is supposed to be in the library.

  1. Molly - good considerations. This is precisely why the students at Codman will be monitoring temperature and levels of Ph, amonia, nitrite and nitrate on a daily basis.

    Interesting anecdote in regards to soil depleation: In 19th century Europe, the Danish developed a process of planting clover on fields in between crop rotations to replenish nitrates in the soil. The technique flooded through Europe and America, only to be eclipsed by artificial petroleum based fertilizers after world war 2.
