Fewer fertilisers
For years farmers have known that the clever wild flower clover is a natural fertiliser. Sowing clover underneath their crops increases nitrogen levels in the soil. This nugget of know-how helps to increase crop yields.
But now they're bringing another smart idea to the party. Satellite imagery can reveal which areas of land need a boost from nitrogen fertilisers to help crops grow properly.
By only using chemical fertilisers where they're really needed, farmers save money and help stop environmental damage.
Raph says: 'Why wait for GM technologies when we're not sure they'll increase crop yields? We already have simple solutions.'
