Description
| - The soil improving effect of SOM on yields, i.e. the effect which cannot be reached by a sufficient and equivalent nutrient supply, was 6% (average of 350 yield comparisons form 16 LTEs at 12 different sites, the majority for the period 2001-2010), being lowest for winter wheat (3%) and highest for potatoes (9%). SOC contents in the topsoil of long-term (decades) unfertilized treatments range between 0.36 and 1.57% for 18 analysed sites; SOC differences between unfertilized and optimaIly fertilized treatments are on average 0.3%. Considering that under farm conditions, the 'unfertilized' treatment (i.e. no mineral or organic fertilization over a period of decades) does not exist, relevant SOC differences for farms are often <0.2% (or <9 t ha-I SOC). The course of management-induced (e.g. crop rotation, fertilization, soil tillage) changes in SOC depends on the starting level of SOC; equivalent treatments may lead to an increase in SOC from a low starting level, but a decrease from a high starting level. Bare fallow affects the soil carbon budget most strongly; without organic matter input from harvesting and root residues, the SOC content decreases considerably after a short period of 10 years. To evaluate nitrogen utilization by crops, an atmospheric N input (bulk deposition, gaseous immission, a symbiotic N2 fixation) of up to 50 kg ha-1 a - I has to be considered.
