Conteúdo: |
No Terceiro Milênio da era cristã, a irrigação é uma técnica consolidada para a produção agrícola e presente em vários países. Sua importância e indispensabilidade vêm sendo registradas por pesquisadores, professores, técnicos de nível médio e superior e, sobretudo, por agricultores. Atualmente, a quantidade e a qualidade de alimentos, fibras e energia não seriam possíveis de alcançar, sem o uso da aplicação artificial de água no solo para suprir as necessidades hídricas dos vegetais. |
