Organic matter decomposition and microarthropod community structure in corn fields under low input and intensive management in Guaíra (SP)

Abstract: The rate of organic matter decomposition and the structure of the communities of microarthropods were compared between two corn fields receiving contrasting agricultural management practices (low input and intensive farming). The rate of decomposition tended to be higher in the intensively managed field in the beginning of the growing season, but decreased to a level significantly lower than the observed in the low input field by the end of the growing season. This suggested that the biological community assoc… Show more

“…Observed organic matter decomposition rates ranged from 15 to 45% of organic carbon loss in a 20-day period. Rodrigues et al (1997) observed, in corn cultivated during the summer, values reaching 70% of carbon loss in a period of 30 days. There was no difference among results from the organic and the conventional systems (Figure 3).…”

“…Poucos estudos referentes à avaliação do impacto ambiental de práticas agrícolas em agroecossistemas e de práticas de manejo florestal, por meio do estudo da mesofauna e até mesmo da acarofauna, têm sido realizados no Brasil (VALLEJO et al, 1987;RODRIGUES et al, 1997;MINEIRO, MORAES, 2001e 2002OLIVEIRA et al, 2001;MORAES et al, 2011 VÁSQUEZ et al (2007) verificaram que os Prostigmata foram os mais abundantes nos levantamentos realizados em duas localidades da Venezuela. Porém, estudos realizados com a acarofauna de solo e folhedo de floresta tropical na Austrália (Plowman, 1979) e em mata e seringal (MINEIRO, MORAES, 2001e 2002 indicaram elevada abundância de Mesostigmata e baixa de Trombidiformes, resultados esses compatíveis aos observados neste estudo.…”
