Soil organic matter degradation in long-term maize cultivation and insufficient organic fertilization
Original language description
Soil organic matter carbon (C-SOM) compounds degradation was observed in long-term field experiments with silage maize monoculture. Over a period of 26 years, the content of carbon in topsoil decreased by 22% in control unfertilized plots compared to 25% and 26% in treatments fertilized annually with mineral nitrogen. With annual wheat straw application (together with mineral N), the content of C(SOM)decreased by 8%. Contrary to that, the annual application of farmyard manure resulted in a C(SOM)increase of 16%. The ratio of carbon produced by maize related to total topsoil C(SOM)content ranged between 8,1-11,8%. In plots with mineral N fertilization, this ratio was always higher than in the unfertilized control plots. With the weaker soil extraction agent (CaCl2), the ratio of carbon produced by maize was determined to be 17,9-20,7%. With stronger extraction agent (pyrophosphate) it was only 10,2-14,6%. This shows that maize produced mostly unstable carbon compounds. Mineral N application resulted i
