- Water is the most critical resource for agriculture; therefore, efficient water use is one of the most relevant challenges that precision agriculture must address. Greenhouse agriculture is a promising approach to evaluate alternatives to improve water efficiency since the different variables can be monitored within a controlled environment. Among these agriculture variables, soil moisture and vegetation index provide relevant information to make farming decisions that contribute to agriculture sustainability. Soil moisture measures the amount of available water for the crops, while the vegetation index indicates the healthiness level of the plants. Available sensors allow the measurement of these variables while the crops continue growing, and Internet of Things technology provides the tools to implement automated greenhouses. This paper evaluates different irrigation scheduling techniques and water stress mitigation strategies to analyze alternatives to improve agriculture water efficiency within a controlled environment.
