The main objective of the research was to demonstrate the increment of temperature and good pathogen control with solarized cow manures. In order to corroborate which of the treatments was the one that produced the highest temperature and eliminated pathogen microorganisms present (fungi-bacteria). The distribution of the treatments in the field was carried out using a randomized design of blocks, with four replications. Temperatures in the different treatments and repetitions of manure piles were sampled. The temperatures were recorded by means of analog thermometers at two different operating depths (0-7.5 and 7.5-15). The temperatures showed a behavior with a greater oscillation with a centre orientation to the right of the pile of manure, placing in these orientations the maximum temperatures and the minimum temperatures were oriented in the lower left part of the pile, but solarisation piles shown very good increment of temperatures with values higher to 60°C so these temperatures are very good to pathogens control. In another way the results shown the presence of Escherichia coli, F. interobacteriaceae, Enterobacter sp., Bacillus sp., Mucor sp. and F. saccharomycetaceae, were found in manure without solarizing (control). Also Giardia and Crptosporidium were found in the T additional experimental unit and removal after solarisation process
