	We report on a precision measurement of gravitational acceleration using ultracold strontium atoms confined in an amplitude-modulated vertical optical lattice. An uncertainty &Delta;g/g&asymp;10<sup>-7</sup> is reached by measuring at the 5th harmonic of the Bloch frequency. The value obtained with this microscopic quantum system is consistent with the one measured with a classical gravimeter. Using lattice modulation to prepare the atomic sample, we also achieve high visibility of Bloch oscillations for &sim;20&thinsp;&thinsp;s. These results can be of relevance for testing gravitational redshift and Newtonian law at micrometer scale.</p>},
