Abstract
Global positioning system (GPS) based farmer digital expert assistant systems (FDEAS) are capable of analyzing the agricultural field and environmental factors associated with the field. The agricultural yield to be harvested, depends on the liquidity content of the soil, the mineral content of the soil, the geographical position of the field, the microbial content of the soil and the temperature of the environment. Other parameters include irrigation, spraying of chemicals, animals or intruders getting into the field, etc. Such a system monitors all these parameters and provides the appropriate values and suggestions to the farmers. Several factors are monitored using different set of sensors. The location, specified by the GPS, can be compared to existing databases of soil maps and thus provide the nature and type of crop to be cultivated with all specifications to obtain maximum yield at that location. Cameras may be employed to continuously monitor the field and initiate alerts. All sensor outputs and systems can be integrated with a GSM modem which sends alert messages as SMS or recorded audio alerts when required. Such a system would ensure real time monitoring and should provide expert assistance for attaining maximum efficiency. It would act as a holistic system for analyzing, monitoring, alerting and assisting farmers at different stages of farming.

Agriculture needs to be assisted by technology in order to enhance its efficiency
Several expert systems have been developed for agriculture applications, but still none is able to provide a holistic solution [2,3,4,5,6,7,8,9,10,11,12,13,14,15,16]
Microbes play a major role in healthy growth of crops and to perform efficient cultivation the amount of microbes present should be monitored constantly. To achieve this task N2O and other types of gas sensors can be employed which would monitor the concentration of gas liberated by the microbes, which is directly proportional to the amount of microbes
Summary
Agriculture needs to be assisted by technology in order to enhance its efficiency. a country is tagged as developed only when the field of agriculture grows in parallel or in pace with the other fields such as infrastructure, technology, equipments, etc. The environmental and economic benefits of IMPP are beyond doubt, its use has been somewhat limited due to the required amount of knowledge on climate, topography, soil type of the farm, agronomic practices, crop phenology, biology and damage potential of the pests and options available for suppressing their population below the economic injury levels Since this knowledge is within expert’s level, in order to make it available to farmers, an expert system namely CPEST for managing pest and diseases of coffee in a developing country has been developed [11]. Most of the existing studies were on the implementation of technologies to improve individual processes like the efficiency of seeds, pesticides and insecticides application, etc In this case the approach it to incorporate electronic, instrumentation and information technology to develop an integrated digital assistant to address a system of processes. The system developed is designed to bridge the adoption gap between the farmer and technology by bypassing the complexities involved in handling the device and exposing only the simple procedures
