CUMELA NEDERLAND

• Interest Group of 2.000 companies• Companies are farm contractors, companies for land

development (infrastructure) and distribution of manure

• Located for 90% in the rural area, 30.000 employees• Average annual turnover € 1,3 miljoen / company

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

Long distance transport of liquid manure

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

Manure injection in arable land

Loading of manure out of the container

Specialized equipment

Protection the structure of the soil

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

Thanks for your attention
