M. do  aSoil physical quality under long-term integrated agricultural production systems.h[electronic resource]  c2019  aIntegrated farming systems lead to high quality and quantity of food as well as better environmental quality, but these systems can provide some disadvantages, such as the possibility of occurrence of soil compaction, which can be detected through soil physical quality indicators. The aim of this work was to analyze the effect of long term Integrated Crop?Livestock (ICL) and Integrated Crop?Livestock?Forestry (ICLF) systems on soil physical quality. The experiment (randomized complete block design) was carried out from 2006 until november of 2012 at IAPAR research farm, Ponta Grossa, Paraná state, under soils with sandy loam texture. Soil depths of 0.00?0.05, 0.05?0.10, 0.10?0.20, and 0.20?0.30m were sampled in November 2012 to analyze soil physical quality. The soil relative density, structural stability index, S index, relative field capacity, plant-available water capacity, bulk density alert value, and least limiting water range were evaluated. Both integrated systems (ICL and ICLF) provided adequate soil physical quality; nevertheless, overall, the ICL system resulted in better quality. Our results showed that the forestry component in the ICLF system negatively affected the soil physical quality mainly at the 0.05?0.10 and 0.20?0.30m layers.  aIntegrated agricultural systems  aSoil structure  aLeast limiting water range  aPlant-available water capacity1 aCAVALIERI-POLIZELI, K.
