Agriculture plays a significant role in economic development for the African continent. For example, 45% of the Kenyan revenue is generated from Agriculture.  In Africa, agricultural activities are primarily dependents on rain which is an insufficient source and thus the need for irrigation. In order to enhance water utilization efficiency and increase crops productivity, a new system called Dynamic Soil Moisture Control System (DSMCS) for irrigation using Global System for Mobile Communication (GSM) technology is introduced. The proposed system uses PIC16F877 microcontroller, dc motor, soil moisture and water level sensor to monitor any changes in the soil moisture content in the farm and water level in the irrigation tank. The GSM modem is configured using Attention (AT) commands to enable a real-time monitoring of the farm remotely. All the status of the farm are dynamically monitored using DSMCS and send to the farmer through short messages (SMS), which resolves the distance and range problem. From the results obtained, the proposed system ensures adequate irrigation to plants based on soil moisture content and thus minimized water wastage.
