BIOFERTILISERS
Juanfran Lopez
Liquid fertilisers containing:
1) Live or latent cells of efficient strains
2) Microbial byproducts
Why are Biofertilisers successful? Contribute:
1 microbes
Restore the soil's natural nutrient cycle and build soil organic matter
2 Compounds
Stimulate plant growth, decrease pest incidence, stimulate composting and
ameliorate the soil
3 Mineral Chelation
Mineral Chelation Last step of minerals degradation before plant uptake
bioavailability of minerals

BENEFITS OF DOING BIOFERTILISERS AT HOME
• Low investment (Ingredients & equipment)
• Easy to get Ingredients
• From backyard up to bio factory
• Common sense technology
• Possibility to combine with other land management

Traditional uses of biofertilisers
• Feed crops
• Protect crops from pest and disease
• As soil inoculant (support soil food web)
• As root inoculant
• As seed inoculant
• To treat crop rests and refuses
• To start composts
