Modern Agriculture's Nitrogen Crisis

• Modern farming systems increasingly sick - 70% nitrogen fertilizers leak out uncontrollably
• Green Revolution nitrogen consumption: 30-fold increase from 5 million metric tons to 250 million metric tons
• Result: Only 4-fold increase in global food grain production despite 30-fold fertilizer increase
• Efficiency gap: 30x fertilizer increase supporting only 4x production increase

Nitrogen Fertilizer Problem Mechanism

• Applied nitrogen mostly in ammonium form - binds soil, doesn't move, creates no harmful byproducts
• Soil bacteria consume ammonium fertilizer, convert to nitrate + harmful nitrogen byproducts
• Nitrate problem: Cannot bind to soil, washes out during rain/irrigation
• Historical bacteria activity: Small subdued microbial activity grown into monster
  • Consumes 95-99% of fertilizer nitrogen
  • Spits out as nitrates
• Question: Are we fertilizing crops or feeding bacteria monster?

Environmental Impact

• Nitrogen moves into water streams, pollutes lakes
• Triggers algal blooms, creates "another Green Revolution" in ecologically destructive way
• Disrupts soil microbial universe from 7 decades of Green Revolution

Soil Microbial Ecosystem

• Soil = living biological system with invisible microbial world
• 1 gram soil contains 10 billion microbial cells
• Functions: Breaking down components, nourishing crops
• Complexity exceeds above-ground ecosystem
• Population larger than entire human population on Earth
• Severely affected by large nitrogen fertilizer infusion
• Changed population dynamics - small insignificant activity grown to monstrous proportions

Nature's Solution: Brachiaria Grass

• Black era tropical pasture grass from South America
• Unique ability: Produces large amounts of antibiotics from root systems
• Antibiotics specifically target nitrifying bacteria
• Controls nitrifying bacteria function without killing - keeps in "comma state"
• Results: No nitrate formation, no nitrogen gas emissions from pastures

Crop Production Context

• 4 main crops provide global food security: wheat, maize, rice, sorghum
• 80-90% food grains produced from these 4 crops
• 90%+ industrial nitrogen fertilizer goes to these 4 production systems
• Staple crops lack antibiotic production ability - reason for nitrogen leakage

BNI Wheat Development

• Wild wheat produces 20-30x more antibiotics from root systems than cultivated wheat
• 15-year research project to relocate genomic region responsible for antibiotic production
• Successfully transferred wild wheat chromosome segment (orange portion) to cultivated wheat
• Integration achieved without disrupting:
  • Elite wheat architecture
  • Yield potential
  • Bread-making quality

BNI Wheat Results

• New category called "BNI weeds" - produce large antibiotic amounts from root systems
• Control bacteria to prevent nitrate production in root systems
• Nitrogen fertilizer stays in root zone, doesn't leak
• Field comparison: BNI wheat healthy/green vs. modern wheat leaking all nitrogen
• Both plots received same nitrogen amount at same time
• BNI wheat retained nitrogen in farmlands vs. modern wheat leaching

Future Timeline

• BNI wheat = Next Generation in development
• Available to farmers in few years
• Goal: Next 10 years most wheat grown globally will have this ability
• Expected outcome: Stop nitrogen leakage through root-system antibiotic production
• Will reduce nitrogen fertilizer requirements in future
