Smart agriculture is a concept based on the use of ICT as well as automatization and robotics. It helps farmers manage production based on precision and optimization. It represents sustainable developnment that offers solutions to major problems of today's age such as population growth and climate change. Application of smart agriculture worldwide is growing more and more, especially in crop husbandry. Its advantages are many but they primarily relate to increasing yields and reducing environmental pollution. Despite the many advantages it offers, the disadventages related to smart agriculture that are slowing her implementation are the high costs of production and the need for certain knowledge and skills to use the technologies that this method of agricultural management includes. The aim of this paper is to explain the concept of smart agriculture using collected literature. Thus, this paper presents all of the technologies that are part of smart agriculture, aswell as the application of smart agriculture itself and also all the advantages and disadvantages of its implementation. This paper confirms that smart agriculture is currently one of the best forms of sustainable development that helps in reducing harmful impact on environment and increasing overall yield of agricultural production.
