Chromatography Gallery

Veracruz Day#5

Soil Chromatography is an incredibly interesting way to visualise our soil and the biological processes that are occurring within it. For me, it is also the point where science and art intersect.
You’ll be able to read all about the how and the why of Chromatography in the Manual on Soil testing that we are producing at the #LabICMx but I thought I’d share some of the photos from the day.

I can’t wait to try this technique with many different types of soil and other things like vegetables and foods… Art and science… Amazing!

Veracruz Day #4

Today we headed out to do our field work with the Urban Lab at Boca del Rio. In all we collected samples from 4 different sites.

Site 1 was visit to a kids daycare centre where in the near future a veggie garden will be installed. 2014-11-26 17.31.502014-11-26 17.33.20

The house of Santiago’s mum was the site of our 2nd visit. They have a lovely 2 hectares with dogs, chickens, ducks, pigs and a large veggie garden. And would you believe it, the family is from Catalunya! As they say, the world is a tissue… (or is that only in Spanish???)2014-11-26 18.18.54 2014-11-26 18.20.29

We then headed back to the lab to take some samples from the land there before riding bikes provided by the Boca del Rio council to take some samples from the beach.

All in all a great day out in the field (much nicer than being in the office!!!) and a huge thanks to Alejandra, Alexandro and Santiago from the Laboratorio Urbano and Citycultores for being our guides for the day!

Laboratorio Iberoamericano de Innovación Ciudadana.

Good news this week; Our project “Soil, Food and the City” (“Suelo, Ciudad y Alimento“) was one of ten projects selected from around the world to be developed at the MediaLab Prado Citizen Innovation workshop to be held in Veracruz, Mexico, in November.

The objective of this project is to create a low-cost tool that we can use to evaluate the quality of soil in an urban setting. With this tool we’ll be able to map empty lots in the city which have the potential to be used to grow food, with the end goal of achieving food sovereignty and security.

To create this global picture of urban soil quality we’ll conduct various tests. These tests would be conventially divided into three ‘boxes’ or subsets of tests, each with its peculiarities and advantages. The kits consist of affordable and sufficiently qualitative tests for the assessment of soil properties in urban and peri-urban sites. The complementary nature of each test will help citizens and scientists to gain an overall understanding of soil health and processes.

So if you think you’d be interesting in helping us develop this project, or to learn more about the workshops as a whole check out the collaborators page here.

mediaLab Prado: Laboratorio Iberoamericano de Innovación Ciudadana

This week we’ve sent off a project that we hope will be included in the MediaLab Prado “citizen innovation” workshops that will be held in late November in Veracruz, Mexico.

Our project relates to soil health in urban and peri-urban areas and how ordinary citizens around the world can learn more about their soil, its processes, what it contains, and even how to improve it using open source tools. Click the pic below to read more about the workshop.

We’ll know if we will be on our way to Mexico in the first week of September, so until then, fingers crossed as we tend to the veggie garden!
