Rosa's Field Trials

Rosa writes:

"...My work is located in the Los Andes province, 30 minutes from the city of El Alto; it is at the Callutaca Campus. I have classes and work on practicums there in vegetable and compost production. We work on different demonstration parcels with highland crops such as barley, cañahua, quinoa, broad beans, tarwi, skinless potato, oca, bitter potato, etc. in different soils...
I participated in the production of organic fertilizer from organic material, where the teachers assigned us the conscientious collection of kitchen scraps that we had to bring each Saturday. That is to say, [our scraps were] a major percentage of the contributed organic material, along with a quantity of small-animal manure (sheep, guinea pigs).
