Nesse contexto, a hipótese desse trabalho é que o menor revolvimento do solo, manutenção de cobertura deste com palha e adubação podem reduzir a densidade de plantas daninhas monocotiledôneas durante os cultivos estivais ao longo do tempo. Assim, o objetivo dessa pesquisa foi avaliar a densidade de plantas daninhas monocotiledôneas emergidas no início do ciclo das culturas estivais, do sétimo ao décimo ano de aplicação de diferentes sistemas de manejo do solo associados a formas de adubação. Houve aumento da densidade de plantas daninhas monocotiledôneas com o incremento do distúrbio mecânico do solo e a retirada ou queima dos resíduos culturais, demonstrando a importância do sistema de plantio direto na redução da infestação dessas plantas. As formas de adubação não afetaram a densidade de plantas daninhas monocotiledôneas. |

The soil macrofauna, comprised of invertebrates > 2mm, includes both beneficials and pests of agricultural crops ( e.g., termites, ants, eartworms, beetle white-grubs, true-bugs, snails, milipedes, centipedes, spiders, crickets, larvae of insects and other). Their diversity tends to be low in highly-disturbed systems such as those with conventional tillage (CT) and pesticides, but can be increased with appropriate soil and ecosystem management, including organic matter addition, no-tillage or direct drillings (NT) and crop rotations. Their activity is important for soil physical, chemical and biological properties and processes and also for plant growth and ecosystem productivity. Studies on the soil macroinvertebrate communities in the region of Londrina began in 1998, in private farms and research trials with different crop management systems. Soils of the region are primarily clayey (>65% clay) distrophic or eutrophic Red Latossols (Oxisols and Ultisols). Sample were taken in summer (mainly) soybean) and winter crops (mainly wheat and oats) under various tillage and crop management practices (including NT and CT) and in native forests, using the TSBF (Anderson and Ingram 1993) methodology. The total number of mosphospecies, orders and N taxonomic groups sample-1 were measured per land use system. In the native Atlantic Forests, total group diversity ranged from 25 to 27 taxonomic orders, and total diversity ranged from 82-126 mosphospecies. The number of orders per monolith ranged from 13-18, indicating high diversity per sample, and a more even distribution of the diversity over the sample area. Ants and termites predominated, and the most diverse group were the ants (11-22 mosphospecies), followed by beetle adults (13-19 morphosp.), beetle larvae (12-13 mosphosp.) and spiders (8-11 mosphosp.). In the agroecosystems, total group diversity was much lower, ranging from 12-13 orders in CT to 16-18 orders in NT and minimum tillage (MT). The number of orders per sample was also lower, ranging from 6-7 orders in CT and 10-11 orders in NT and MT. Studying the community composition of the soil fauna is important for the holistic understanding of the soil and its function, since the equilibrium/disequillibrium processes of these communities can result in the explosion of pests, the loss of good soil physical structure, soil fertility and productive potential. So far, very few measurements of the soil fauna communities and their diversity in agricultural systems have been perfomed in Brazil and, due to their importance for soil function (e.g., pest or ecosystem engineering effects, sensu Lavelle et al., 1997), these organisms deserve more attention.
