The soil macrofauna, i.e., organisms easily visible that live in the soil or on its surface for at least some part their cycle, includes invertebrates considered both as pests and/or as beneficial to the soil environment and plant production. Ants, termites, earthworms, beetles, grubs, pill-bugs, true bugs, cicadas, snails, millipedes, centipedes, crikets, wasps, spiders and various insect (especially moth and fly) larvae all form part of the soil macrofauna community. They include saprophagous organisms that act as decomposers and mineralizers, root and shoot-feeding organisms that negatively affect plant growth, predators and necrophages that feed on other organisms, geophagous bio-turbators that burrow through the soil leaving their excrements on or under its surface, social insects that create nests and congregate in large numbers, and omnivorous organisms, that feed on many different substrates. The aim of the presente study was to asses the soil macrofauna communities in different land management systems and native Atlantic forest in the region of Londrina, Brazil, focusing on the community composition and the abundance of the various groups comprising the macrofauna community. This would then help identify the key organisms present, that would be further studied, to test for their functional significance in the agroecosystem (e. g., pest or ecosystem engineering effects). Samples were taken in the summer crop (soybean) and after winter wheat harvest, in plots with 8, 13 and 20 years of conventional planting (CT: disk plow), chisel plow (MT) and no tillage (NT), planted with continuous double crops (wheat/soybean) or crop rotation (lupine/maize-oats/soybean-wheat/soybean). Both in the summer (soybean) and winter season, under NT and MT a larger number of geophagous (earthworms), saprophagous (millipedes, termites), predatory (spiders, diplura, pseudoscorpions and centipedes) and some pest (moth larvae) organisms was higher than in CT, where a larger number of enchytraeids (saprophages) and beetles (some pests) were observed. In the winter season, a much higher number of ants was observed under NT and MT versus CT, and in general, a higher total number of macrofauna was found in the former systems compared with CT. In the summer season, the differences in abundance between management systems was mostly due to a lower number in MT versus CT and NT. Total abundance in the agroecosystems in both seasons ranged between 1000 and 2000 individuals m-2. On the other hand, in the native forests, macrofauna abundance was much higher than in the agroecosystems. In the winter >3000 and in the summer, >11,000 individuals per m² were observed, with predominance of ants and termites. The use of no-tillage as opposed to conventional tillage practices, especially when combined with crop rotations and cover crops, can enhance soil macrofauna populations and their contribution to soil function, leading to a more balanced community composition. The present results highlight the importance of agroecosystem management practices on soil macroinvertebrate communities and the role of adequate decision-making, in achieving a more balanced soil fauna community composition, thus enhancing its potential benefits to soil fertility, crop production and sustainability.
