Abstract: A system for maintaining soil characteristics for a geographical region is described, the system includes of a processing unit connected to the sensing unit for comparing the plurality of soil characteristics determined by the sensing unit with a predefined soil characteristic value stored in a database to determine the soil characteristics, wherein if the plurality of soil characteristics deviate from the predefined soil characteristic value, then the plurality of compared soil characteristics are adjusted to match with the predefined soil characteristics; and a prediction and recommendation unit connected with the processing unit for predicting at least a disease based on the deviated soil characteristics and generating recommendations for maintaining the deviated soil characteristics to make the soil ideal for crops and reduce risk of the predicted diseases.
