Abstract
The aims of this study was to evaluate the possibility of reducing the weight of manure in
paddocks by natural evaporation according to an appropriate management plan. The weight
of buffalo manure was recorded by an experimental platform equipped with load cells and
installed within the paddock. The data was used for assessing the real evaporation of
manure in situ. A model for predicting manure evaporation was developed by adapting a soil
evapotranspiration model. On the basis of the model an optimal management strategy was
established, which corresponds to minimizing the use of the scraper from the 100th day of the
year (DOY) to the 250th DOY. This lead to a potential reduction in weight of the manure by
650 kg/m2/year which corresponds to management cost reduction of about 30%. This
approach is effective for reducing the bulkiness of buffalo manure for which the spreading
costs per kg of nitrogen and the fuel needs for land application is very substantial considering
its low nitrogen content of about 2 mg/m3.
