Scientific researchers have applied newly developed technologies, such as sensors and actuators, to different fields, including environmental monitoring, traffic management, and precision agriculture. Using agricultural technology to assist crop fertilization is an important research innovation that can not only reduce the workload of farmers, but also reduce resource waste and soil pollution. This paper describes the design and development of a water-fertilizer control system based on the soil conductivity threshold. The system uses a low-cost wireless sensor network as a data collection and transmission tool and transmits the data to the decision support system. The decision support system considers the change in soil electrical conductivity (EC) and moisture content to guide the application of water-fertilizer, and then improves the fertilization accuracy of the water-fertilizer control system. In the experiment, the proposed water-fertilizer control system was tested, and it was concluded that, compared with the existing traditional water-fertilizer integration control system, the amount of fertilizer used by the system was reduced by 10.89% on average, and it could save 0.76–0.87 tons of fertilizer throughout the whole growth period of cotton.


The primary objective of this current paper is to design, develop and automate an approach called the Hypsometrical Approach (HA). This approach automated and developed as a decision support system using environmental indicators for managing and planning water resources. It servers to analyze and to make comparison of various current and future scenarios of different quantifiable indicators for any consideration and for various socio-economic aspects. It is also used as a decision tool to improve or at least to preserve environment and natural resources. HA needs to draw its data from different sources like satellite images and watershed information system such as watershed characteristics including equipment infrastructures (Drinking water supply, irrigation system), transportation infrastructures (Roads, dams), natural resources (Water, soils, and vegetation), human activities (Agriculture, urbanization and industry) and different socio-economic factors (Demography). Globally in this paper the automation of this Hypsometrical Approach is divided into two main parts, the first part based on identifying and extracting data pixel by pixel from classified satellite images using python programming language, and the second part related to the development of a system allowing users to generate and visualize different curves called hypsometrical curves developed using Java programming language. We can combine any hypsometrical curve with arithmetic operations (addition, multiplication, subtraction and division) in order to assess some other indicators such as water resources, watershed storage capacities, vegetation, soils and forest potentials curves. Briefly, the objective of automating hypsometrical approach is to make efficient decision to improve the socio-economic level and enhance sustainable development.
