System of Crop Intensification - in Chao Sobral


SRI methodology is based on four main principles that interact in synergistic ways:
  • Establish healthy plants early and carefully, nurturing their root potential.
  • Reduce plant populations, giving each plant more room to grow above and below ground and room to capture sunlight and obtain nutrients.
  • Enrich the soil with organic matter, keeping it well-aerated to support better growth of roots and more aerobic soil biota.
  • Apply water purposefully in ways that favor plant-root and soil-microbial growth, avoiding flooded (anaerobic) soil conditions.
