Fertilizer Solutions –
for global food security and the environment
Virtual Fertilizer Research Center presented by
Dr. Prem S. Bindraban December 4, 2013
Virtual Fertilizer Research Center
• The VFRC is
– A research initiative to foster the creation of the next generation of fertilizers and production technologies
– to help feed the world’s growing population and provide sustainable food security
The pharmaceutical and seed industries spend billions on R&D.
Pfizer, Glaxo, Merck ~ 16% of revenues is
invested in R&D spending
Syngenta, Monsanto ~ 9% of revenues is
invested in R&D spending
~ 0.01% of revenues in R&D for new products and
new technologies
Industry Research and Development Spending
The Essence of Fertilizers
• Necessary to enhance plant growth over ecological/natural rate of growth
• Undersupply causes soil nutrient mining and degradation of ecosystem functions
• Overuse causes GHG emissions and eutrophication
• Essential for production of sufficient food

Fertilizer solutions
• Immediate – Inappropriate application
• Time, place, amount, distance to roots
• Unbalanced composition
– Socio-economic, institutional arrangements • (Market) infrastructure (price, bag size, etc.)
• Incomplete agronomic “package”
• Risk to investment
• Opportunity costs
• Leap frog development – Change fertilizers themselves
– Novel “packaging” of nutrients
– Fertilizer industry to innovate

Biology driven fertilizers • Current
– Chemists and industrial processing engineers develop fertilizers
• Paradigm shift
– Understand plant nutrition metabolism and nutrient transport mechanisms
– Novel “packaging” of nutrients
– Biologists to guide chemists

Pesticide development
Repackaging nutrients • E.g. Foliar fertilizers – high tech for low income farming
– Reduce risk • poor availability soil nutrients; correct deficiencies; rainfall variability
– Reduce nutrient losses – Simultaneous application multiple (balanced) nutrients
• Much trial-and-error research – “soil” fertilizers used for foliar – Application doses random – Efficiency very low to high
– Crops response highly variable • Yield, Quality, Metabolic efficiency

Cockpit
Foliar sprays • Nano-carriers • Biological carriers
Biological activity • Micorrhizae • Endophytes
Species • Rooting • Exudates • Symbiosis
Mining/Industrial processes • Efficiency • By-products • Labeling
Physiological traits • Stomata • Components • Storage
Quantify Prioritize
Breeding • Novel traits
Soil application methods
Purification • N, P, Fe, S, Zn, Cu...
Recycled product • Fermentation • Rendering • Other...
GHG (NO2, N2O, NH3) • Capture at source • In-house filtration • Tractor fertilizer
Assessments • Geo-spatial priority • Agro-ecosystem-specific
Soil diagnostics
Aerial diagnostics Infusion (in stem) • (Fruit) Trees
Changing the fertilizer game
• Technological Innovations – From bulk fertilizers to specific packaging of nutrients – Less volume more added value – Carrot and stick
• Stakeholders – Direct (Fertilizer industry, Traders, Farmers)
– Indirect (Food Industry, Health/medical sector)
– Global change (Climate change, World Water Council)
• Mainstream Nutrients – In Policy – In Research – In Sustainability debates
