Precision agriculture is becoming an acknowledged method of crop farming and has become an important method to acquire agricultural outcome in a sustainable and environmental friendly way. Additionally, increasing attention towards automated data, acquisition & knowledge processing is leading towards augmented agriculture management and increased capability in crop production. The advantage and effect of using precision agriculture technology is eminently abased on the abilities of integrated technology along with human efforts. The study related on the subject is centralized on the basis of survey and research on history, development, applications, and benefits of precision agriculture, especially for small scale farms. Consequently, work was analyzed and research data was reviewed in the paper. Precision agriculture imparts with an innovative approach using modern techniques to provide bran d new solutions for present day farming problems, which basically includes balanced productivity with environmental protection.
