Biointensive Method

View details

How it works

The biointensive method is based on deep soil preparation through double digging, which improves aeration, water retention, and plant root development.

Locally produced compost is incorporated to restore soil fertility. Crops are established in high density under association and rotation schemes.

The system is based on eight agroecological principles prioritizing soil health, productive efficiency, and ecological balance.

Impact

  • Higher productivity in small spaces
  • Recovery of degraded soils
  • Elimination of chemical inputs
  • Sustainable compost production
  • Protection of local biodiversity

Biointensive Family Gardens

View details

How it works

Families design their gardens considering relief, drainage, water flow, and solar exposure. Permanent beds are built to conserve soil structure.

Organic fertilizers and efficient irrigation systems are used. Crop selection responds to criteria of complementarity and local adaptation.

Impact

  • Direct improvement in family nutrition and health
  • Diversified production throughout the year
  • Efficient water use
  • Income generation through surpluses
  • Greater food autonomy
🪴

Biointensive Beds

View details

How it works

Crops are established in raised beds 10 to 15 cm high, separated by paths to avoid soil compaction.

The productive design follows the 60-30-10 rule: 60% calorie crops, 30% high-efficiency roots, 10% nutrient-dense vegetables.

Impact

  • Conservation of soil structure
  • Sustained long-term productivity
  • Compost optimization
  • Complete annual diet production in small spaces
  • Resilient system against intense rains

Seed Dryer

View details

How it works

The system allows upward hot air circulation through mesh trays where seeds are placed. This prevents contact with dust, moisture, and insects.

Impact

  • Conservation of local seeds
  • Protection of genetic diversity
  • Reduction of post-harvest losses
  • Strengthening of food sovereignty
