A drenagem nos cultivos sem solo: Um resíduo ou um recurso? Parte I/II

Abstract

No cultivo sem solo em substrato, a necessidade de regar com excesso de água em relação às necessidades das plantas gera um volume apreciável de drenagem, que é do todo o interesse não desperdiçar, por razões económicas e ambientais. Esta drenagem pode ser reciclada, por incorporação na preparação de nova solução nutritiva, ou reutilizada na fertirrega de outras culturas. A reciclagem apresenta o risco de disseminação de algumas doenças, sendo por isso aconselhável usar previamente algum método de desinfeção. Na reutilização, o risco é menor se as culturas a regar forem menos sensíveis a doenças cujo inoculo possa estar presente na drenagem, mas poderá implicar uma diversificação de atividade agrícola, isto é, passar a dispor de outras culturas para a sua aplicação. São apresentados os métodos mais correntes de desinfeção da drenagem, bem como medidas para a sua redução e valorização
