Assessment of the soil N supply capacity is essential to optimize fertilizer N use. We investigated soil N supply capacity and fertilizer N recovery for three cropping systems established in 1977: silage corn (Zea mays L.)–cereal without (CC) and with 20 Mg ha–1 yr–1 manure (CCM), and silage corn–fo...
