Key figures Netherlands
• 16,6 million inhabitants• 1,85 million ha agricultural area• 975.000 ha grass-land; 240.000 ha silage maize• 642.000 ha arable land• Of which 194.000 ha cereals• With average yield of 8.900 kg wheat per ha

Key figures live stock production
• 2,4 million cattle, 12,2 million pigs, 85 million poultry• Production 73 million ton manure; 20 million surplus• Destinations for the manure surplus:
15,6 million ton transported to other farms as fertilizer 2,0 million ton to treatment facilities of manure 2,4 million ton for export (Germany, France)

Innovations in manure distribution
• Specialized companies with trailers and tank-cars for long distance transport of manure to cropfarmers
• Storage facilities at the farms of crop farmers• Manure spreading equipment with injection of manure• Tracking and tracing the transports of manure, • Sampling and analysing the manure per transport

Unloading liquid manure into a container

Injection of liquid manure
• No smell• No emissions of ammonia• No losses of minerals (N)• Precisely farming (fertilizing)• Maximum profit of the minerals in manure• Saving costs for chemical fertilizers

Advantages natural fertilizers
• Organic matter for better soil structure• More biological soil activity• Better quality crops and higher yields• Reduce of chemical fertilizers and costs• For Dutch crop farmers also the price: “for free”

Possibilities for cooperation
• New natural fertilizers are avaiable for Hungarian market• Hungary is big country of crop farmers (cereals)• Netherlands is big market for cereals for feed production• Shortage of imported non-genetical manipulated cereals in
the EU• Business of substainable recycling of fertilizers and raw
material feed
