Comparação entre balanço hídrico climatológico e balanço hídrico de campo para uma cultura de café.

Abstract

Water balances are of great utility for water management of agricultural crops. One class of these balances is called climatological since they are based exclusively on atmospheric data, while another class envolves measurements on soil surface and within the soil. The last ones are more laborious and expensive to be carried out, so that there is an advantage in the use of climatologic balances. For a coffee crop grown in Piracicaba/SP, Brazil, a comparison was made between the climatologic and the field water balances, using data of two years. It was concluded that the climatologic water balance is not equivalent to the field one
