Intensive Planting 3

Biointensive Workshop – Leon 2012

Since 2012, the core mission of BioNica has been to provide training in best practices in sustainable small-scale agricultural – particularly carbon-intensive methods to develop and maintain soil fertility in the tropics so that the soil is capable of growing crops without synthetic fertilizers, herbicides and pesticides.

Participants include:

1) agricultural technicians working with non-governmental organizations (NGO’s) that have small-scale agricultural projects;

2) small-scale growers; and,

3) university faculty and students in agronomy.

ECHO-BioNica Seed System


Peanuts (mani) – February 2014

BioNica and ECHO – in collaboration with the Universidad Nacional Agraria – are in the implementation phase of a “seed availability and diversity system” for small-scale growers in Nicaragua.

Our objective is to:

1) diversify the supply of seeds available to small-scale growers by introducing an assortment of vegetables, legumes and grains; and,

2) diversify the inventory of staple crops by introducing varieties from countries with warmer and drier climates, including Africa and Asia.

BioNica Network of the Growers of Seeds

Six biointensive growers in Nicaragua have begun producing open-pollinated seeds for future distribution to organizations and small-scale growers who practice biointensive-agroecology methods.

Ligia Belli, Peter Schaller and Michael Richardson are coordinating the grow-out of the seeds.

Center for Biointensive-Agroecology

nuevo salón de clases

Classroom at El Plantel

Educational tours are available throughout the year at the Centro de Capacitación, Investigación y Demostración de la Agroecológica Biointensiva (CCID Guanacastillo) located at km 30 of the Tipitapa–Masaya Highway. The tour includes demonstrations of the basic principles of agroecology and the biointensive method of small-scale agriculture. Visitors also may acquire practical experience in digging beds, making compost, transplanting seedlings and harvesting crops.

The CCID Guanacastillo is managed by Javier Silva (ADAR) with assistance from Alexis Hernandez Medal and John Wyss (ADAR).
