This study examines nutrient supply dynamics underpinning cattle performance on three farms in Acre by tracking soil chemical and physical properties over time across grazing and land-use types after clearing. Measurements included forage mass, topsoil nutrient concentrations and soil bulk density across Brachiaria-only, grass–Pueraria mixes, cropland and forest.","Public Disc losure Authorized  \nAUTHOR ACCEPTED MANUSCRIPT  \nFINAL PUBLICATION INFORMATION  \nNutrient Status of Cattle Grazing Systems in the Western Brazilian Amazon  \nThe definitive version of the text was subsequently published in  \nCogent Food and Agriculture, 6(1), 2020-02-09  \nPublished by Taylor and Francis and found at [http://dx.doi.org/10.1080/23311932.2020.1722350](http://dx.doi.org/10.1080/23311932.2020.1722350)  \nPub lic Disc losure Authorized  \nTHE FINAL PUBLISHED VERSION OF THIS MANUSCRIPT IS AVAILABLE ON THE PUBLISHER’S PLATFORM  \nThis Author Accepted Manuscript is copyrighted by World Bank and published by Taylor and Francis.
