Abstract
The influence of long-term fertilization on macroarthropod community composition from a field study with wheat (Triticum aestivum) was investigated. Soil samples were taken from a long-term field experiment which was conducted for 5 years to explore the effect of three treatments: control (non-fertilization), conventional (mineral fertilizers—NPK), and alternative (organic fertilizers—farmyard manure). The highest values of macroarthropod community composition were found in the alternative fertilization system after the 30 years of its utilization. After 30 years, the conventional fertilization system showed lower values for these studied variables compared to alternative fertilization system. Our findings suggest that inputs of organic matter source can change positively the macroarthropod community composition, and these results highlight the importance of considering the long-term effect of mineral and organic fertilizers on the diversity of this biological component and their effect on wheat growth and soil fertility. Thus, the long-term utilization of an alternative fertilization system with continuous input of organic matter may exploit positive situations of jointly beneficial biotic and abiotic conditions.
