    Comparison between climatological and field water balances for a coffee crop
    (Escola Superior de Agricultura "Luiz de Queiroz", 2007-05) Bruno, Isabeli Pereira; Silva, Adriana Lúcia da; Reichardt, Klaus; Dourado-Neto, Durval; Bacchi, Osny Oliveira Santos; Volpe, Clóvis Alberto
    The use of climatological water balances in substitution to complete water balances directly measured in the field allows a more practical crop management, since the climatological water balances are based on data monitored as a routine. This study makes a comparison between these methods in terms of estimatives of evapotranspiration, soil water storage, soil available water, runoff losses, and drainage below root zone, during a two year period, taking as an example a coffee crop of the variety Catuaí, three to five years old. Climatological water balances based on the estimation of the evapotranspiration through the methods of Thornthwaite and Penman-Monteith, can reasonably substitute field measured balances, however underestimating the above mentioned variables.
