8 The coverage path planning (CPP) problem, is a problem belonging to a subfield of motion planning where the goal is to compute a complete coverage trajectory from initial to final position, within the robot workspace subjected to a set of restrictions. This problem has a complexity NP-complete, and has no general solution. Moreover, there are very few studies addressing this problem applied t...

Nanotechnology is an interdisciplinary research field. In recent past efforts have been made to improve agricultural yield through exhaustive research in nanotechnology. The green revolution resulted in blind usage of pesticides and chemical fertilizers which caused loss of soil biodiversity and developed resistance against pathogens and pests as well. Nanoparticle-mediated material delivery to...

We present the initial setup of the Lofar Agro project that concentrates on monitoring micro-climates in a crop field. In addition to the agronomic experiment, Lofar Agro aims at gathering statistics on the wireless sensor network itself. These statistics will form the basis for simulations of algorithms in wireless sensor networks and will be distributed. 1. PRECISION AGRICULTURE In the past f...

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...

abstract the quality of soil maps depends upon their ability to show the soils variability. thus, the accuracy of the maps used for crop recommendations is due to the accuracy of soil maps. this study was performed to investigate the amount of soil properties and crop yield spatial variability in s 2 and s3 units of a semi-detailed quantitative suitability map (1:50000 scale) for irrigated whea...

During the development of precision agriculture technology, prior existence of crop simulation models prompted their application to modeling spatial variation in yield. On the face of it, extending a fairly mature 1-D model of crop growth and yield appeared to be a matter of developing spatial suites of input parameters and running amodel for each set. For many models, extensive literature had ...

This excellent little book will be of great interest to many readers of this journal, in that it treats in considerable detail the concepts, tools, and techniques of precision agriculture (PA), to help ensure food security for future generations. All over the world, more and more grain farmers are adopting the PA methodology, as well as in a broad range of other cropping industries. The book, w...
