The adoption or popularity of the lilies FOMIX PROJECT
experiment is due to:
1-the lilies bulb are highly valued “Lily farming (Lilium longiflorum Thunb.) with
2- the hard work of NGO´s since 20 years biofertilizers and biofumigants in Los
3- the opportunity of being subsidized Tuxtlas, Veracruz, Mexico : an agroecological
Fomix Project approach”
2009- 2011
1 Million pesos = 71500 US $
Funded by Federal and State agency
CONACYT & Veracruz Government
One condition to be financed is to collaborate
With users
Plots in Transition:
•7 communities: Ocotal Grande, Ocotal MEXICO
• 55 farmers with a 100 m-2 plot (2000 bulbs of lilies)
• 3 treatments in their land:
•Solarization +cow manure
•Rotation with innoculated
Mucuna
Jicama (Pachyrhizus erosus )
