In agroecosystems that are subject to extensive management, production is essentially based on the natural site conditions, which means that only a limited quantity of materials are imported into the system, and these usually consist of limited quantities of farmyard manure.
Agroecosystems that are subject to intensive management are characterized by the application of technology which includes the use of machines, mineral fertilizers, and pesticides. In such systems, plant production is not based solely on solar energy but also on fossil energy, which is required for operation of machines and for production and transport of fertilizers and pesticides.
