C.  aIntegrated crop-livestock system in tropical Brazilbtoward a sustainable production system.h[electronic resource]  c2014  aPerformance of soil management systems was initiated in 1995 in a field experiment in Dourados, MS,Brazil, with the following systems: CS ? conventional tillage; NTS ? no-tillage; ICLS ? integrated crop-livestock with soybean (Glycine max (L.) Merr.) and pasture under no-till, rotating every two years, and PP? permanent pasture. Pastures (Brachiaria decumbens) were grazed by heifers with stocking rate adjustedto constant supply of forage. The hypothesis was that rotation of crops and pastures would be moreefficient and present beneficial effects to the environment. More complex and diversified productionsystems may exhibit synergism between components to result in better soil physical structure, greaterefficiency in use of nutrients by plants, greater accumulation of labile fractions of soil organic matter,greater diversity and biological activity in soil, and lower occurrence of nematodes and weeds. Better soilconditions in ICLS allowed greater resilience; over the years of assessment soybean and pasture yieldswere less affected by drought and frost. The ICLS was very efficient, accumulating soil C and reducingemissions of greenhouse gases. Soil quality was improved in integrated systems with larger numberof components and greater interaction between these components (ICLS) compared to simple systems.Based on soil attributes, we affirmed in this long-term study that the ICLS system is agronomically andenvironmentally efficient and sustainable.  acrop rotation  ano-tillage  asoil quality  aAgricultura  aBrachiaria  aCerrado  aPastagem  aPlantio Direto  aRotação de Cultura  aSoja  aSolo  aPasture  aQualidade do solo  aSavana  aSavanna  aSistema de manejo  aSoybean1 aMERCANTE, F.
