There are many different combinations such as partnerships (GbR, OHG, KG), registered cooperatives (eG), limited liability companies (GmbH), investment companies, producer groups, purchasing groups, joint management, even cooperatives that concentrate on urban farming and other – with and without family farmers. There are many more differences between the legal basis and tax-related features. All they have in common is their economic benefit. They want to produce at lower costs to achieve reasonable profits. In all different organized farm types the farmers are linked by contract or like a kind of neighbourhood assistance. Sometimes they provide labour; in many cases they are sharing machines. Many of these associations and communities are not clearly visible in the official agricultural statistics.
