“…From 10 p.m. there was more rain and these occurred until 5 p.m. on 10/05/08. The discrepancies of the occurrence of increased evaporation at higher amount of straw may be attributed to errors of lysimeters during periods with precipitation, as evidenced by several studies published (CAMPECHE, 2002;FARIA et al, 2006). In the present experiment, this failure is evidenced, on 10/05/08, by the values of evaporation in the treatment with 10t of approximately three times larger than ETo.…”

“…Despite the high accuracy of the load cell and data acquisition system, the measures taken for several days after the construction of the lysimeters indicated that the rain reduces measurement accuracy during periods with rain and the wind is the most limiting factor for obtaining measures with high temporal resolution of less than 10 min (CAMPECHE, 2002).…”

“…Durante a condução do ensaio, conforme metodologia apresentada por Campeche (2002), Oliveira et al (2008) e Lima et al (2013) e através da determinação dos erros de medidas, que são utilizados para qualificar os dados em análise, dentre eles: exatidão, precisão, sensibilidade e resolução (CAMPECHE, 2002). No entanto, para este tipo de lisímetro, devese também levar em consideração a estabilidade do equipamento (NASCIMENTO et al 2015).…”

“…Os valores de histerese observados tanto no manômetro, quanto no transdutor de pressão, próximos a origem, podem estar associados ao intervalo de leitura entre carregamento e descarregamento das massas padrão, que foi de dois minutos (CAMPECHE, 2002). Este intervalo é suficiente para que os dois sistemas de leitura possam estabilizar e assim diminuir os erros de histerese.…”
