Soil macronutrient sensing for precision agriculture.
Accurate measurements of soil macronutrients (i.e., nitrogen, phosphorus, and potassium) are needed for efficient agricultural production, including site-specific crop management (SSCM), where fertilizer nutrient application rates are adjusted spatially based on local requirements. Rapid, non-destructive quantification of soil properties, including nutrient levels, has been possible with optica...
متن کاملRobots for Precision Agriculture
Indian agriculture, even after the Green Revolution, is not as productive as it could potentially be. It calls for a second Green Revolution – one of „precision agriculture‟, where cutting-edge technology is used to maximize production with minimum input costs and resources. In this paper we present a multi-purpose agricultural robot to implement precision irrigation, fertilizer addition and de...
متن کاملPrecision Agriculture: An Introduction
gies borne of the information age with a mature agricultural industry. It is an integrated crop management system that attempts to match the kind and amount of inputs with the actual crop needs for small areas within a farm field. This goal is not new, but new technologies now available allow the concept of precision agriculture to be realized in a practical production setting. Precision agricu...
متن کاملPrecision Agriculture Research
Autonomous GPS and three differentially corrected GPS (DGPS) sources were tested under static conditions to assess suitability for precision agriculture applications in the vicinity of Hays, KS. DGPS sources included the U.S. Coast Guard Beacon, Wide Area Augmentation System (WAAS), and OmniSTAR, a commercial service. Both WAAS and OmniSTAR broadcast correction messages from geostationary satel...
متن کاملPrecision agriculture compressed sensing and data fusion algorithm for wireless sensor networks
In order to improve the energy efficiency of WSN nodes and prolong the life of the network, reduce data redundancy. In this paper, proposed the spatial correlation node data compression and fusion algorithm based on the theory of compressed sensing. Firstly, make signal node random projection based on time correlation, then, for random routing instability and network transmission of data fusion...
