Estudos de longo prazo em áreas com sucessivas aplicações de lodo de esgoto (LE) são raros nas condições edafo-climáticas brasileiras. Uma destas áreas pertence ao Instituto Agronômico, em Campinas-SP. Entre os anos de 2001 e 2007 a área experimental recebeu anualmente duas doses de LE calculadas para fornecer 120 e 240 kg ha-1 de N para a cultura do milho ou fertilizante mineral nitrogenado na dose de 120 kg ha-1. De 2008 a 2011 a área não recebeu novas aplicações de LE, somente N mineral no tratamento em que era previsto. O objetivo deste trabalho foi determinar a distribuição de cátions e ânions em extrato aquoso 1:1, simulando a solução do solo, após a interrupção do uso do LE. Para tanto, foram realizadas coletas de solo (camada 0-20 cm) em setembro de 2009 e março e dezembro de 2010. Foram determinados nos extratos os teores de cátions (Ca+2, Mg+2, K+, Na+, Al+3, Cu+2, Fe+2, Mn+2, Zn+2, Cd+2, Cr+3, Ni+2, Pb+2, NH4+) e ânions (NO3-, SO4-2, HxPO4x-, Cl- e F-), além do pH. A análise dos resultados por componentes principais evidenciou a formação de grupos correspondentes aos tratamentos testados e dentre as variáveis identificadas como mais importantes na formação dos componentes destacaram-se as formas nitrogenadas (NO3- e NH4+), cujos teores foram superiores na solução do solo tratado com lodo. |

Large-scale agriculture is increasing in anthropogenically modified areas in the Amazon Basin. Crops such as soybean, maize, oil palm, and others are being introduced to supply the world demand for food and energy. However, the current challenge is to enhance the sustainability of these areas by increasing efficiency of production chains and to improve environmental services. The Amazon Basin has experienced a paradigm shift away from the traditional slash-and-burn agricultural practices, which offers decision makers the opportunity to make innovative interventions to enhance the productivity in previously degraded areas by using trees to ecological advantage. This study describes a successful experiment integrating the production of soybean and paricá (Glycine max L. and Schizolobium amazonicum) based on previous research that indicated potential topoclimatic zones for planting paricá in the Brazilian state of Pará. This paper shows that a no-tillage system reduces the effects of drought compared to conventional tillage still used by many farmers in the region. The integrated system was implemented during the 2014/2015 season in 234.6 ha in the high-potential zone in the municipality of Ulianópolis, Pará. Both soybean and paricá were planted simultaneously. Paricá was planted in 5 m x 2 m inter-tree spacing totaling 228x103 trees per hectare and soybean, in 4 m x 100 m spacing, distributed in nine rows with a 0.45 m inter-row distance, occupying 80% of the area. The harvested soybean production was 3.4 t ha-1, higher than other soybean monocultures in eastern Pará. Paricá benefited from soybean fertilization in the first year: It exhibited rapid development in height (3.26 m) and average diameter (3.85 cm). Trees and crop rotation over the following years is six years for forest species and one year for each crop. Our results confirm there are alternatives to the current production systems able to diminish negative impacts resulting from monoculture. In addition, the system provided environmental services such as reduced soil erosion and increased carbon stock by soil cover with no-tillage soybean cultivation. The soybean cover contributes to increased paricá thermal regulation and lower forestry costs. We concluded that innovative interventions are important to show local farmers that it is possible to adapt an agroforest system to large-scale production, thus changing the Amazon.
