Abstract
Precision Farming merges the new technologies borne of the information age with a mature agricultural industry. It is an integrated crop management system that attempts to match the kind & amount of inputs with the actual crop needs for small areas within a farm fields. This study is basically based on the secondary data and it is a review paper. As it is a review paper so, there was less opportunity to follow any specific method in preparing this paper. Valuable information has been collected through internet browsing, journals etc. In this paper, we examine that, GPS, GIS, VRT, profitability, yield mapping etc. are most common precision agriculture techniques where, GIS can help in site-specific applications of fertilizers and soil amendments and help effectively detect and map black fly infestations, making it possible to achieve precision in pest control. Remote sensing combined with GIS and GPS can help in site-specific weed management. From the review we observed that, the global adoption of yield monitors has been predominated in North-America and Europe. The precision technologies have been used on a wider variety of crops in Denmark and UK than in the US. In Bangladesh, precision agriculture has great prospect as our country is highly natural calamity sensitive and through it we can easily take measure to prevent our agricultural products from damage caused by natural calamities. Though, precision agriculture is very costly but the benefit from it is more than its cost for most of the developing countries. So, the precision agriculture has great prospect in Bangladesh as well as in the world and it is the utmost time to adopt this technology in our traditional agriculture.Res. Agric., Livest.

Highlights
Agricultural production system is an outcome of a complex interaction of seed, soil, water & agrochemicals
We examine that, Global Positioning System (GPS), Geographical Information System (GIS), Variable Rate Technologies (VRT), profitability, yield mapping etc. are most common precision agriculture techniques where, GIS can help in site-specific applications of fertilizers and soil amendments and help effectively detect and map black fly infestations, making it possible to achieve precision in pest control
Precision agriculture (PA) was first expounded in 1980’s in American based on the demands to solve the agricultural environment such as fertilizer and pesticide pollutions
Summary
Agricultural production system is an outcome of a complex interaction of seed, soil, water & agrochemicals (including fertilizer). Precision agriculture merges the new technologies borne of the information age with a mature agricultural industry. A more holistic agricultural approach, PA uses information technology to bring data from multiple sources to bear on decisions associated with agricultural production, logistics, marketing, finance, and personnel. Precision agriculture is an information-based approach to farming that is enabled by a collection of rapidly changing technologies. Adoption of these technologies has been reasonably rapid, it is not clearly understood how to exploit the full power of precision agriculture. Additional research related to precision agriculture should be needs based. Once these key needs are understood, we can develop appropriate research projects to meet these needs. Considering the above facts, the present study was undertaken to know about the precision farming, to be acquainted with the opportunities & need of precision farming and to know the present scenario of precision farming around the world and its prospect in Bangladesh
